Re: 1968 Suzuki T500,Friday 17-Nov-2000 16:59:16,209.162.17.90 writes,I'm in the final stage of a full restoration of a 1968 T-500. Mine sounds like it was in similar condition to yours but probably ran. I paid $600 for it. I have seen a couple for sale on E-BAY but really don't know what they sold for. There are'nt very many of theses around and they are unique as well as being a very good bike they do have a problem with their transmission that you should adress during your restoration. I don't want to discourage you because I feel this is a bike worthy of restoration but you're likely to have as much or more invested in the bike as it's real value if you intend to do a proper restoration. I currently have app. $3500 invested in my restoration and I do a lot of my own work that some people don't. Body panels are hard to come by tank badges are tough the correct seat cover is extremely hard don't lose those big carbs and you may find a few pieces a bit pricey but I would say most of the parts will be found just not overnight. Start by calling Paul Miller Motorcycles @ 860-828-1220. Good luck. This is my second '68 after owning one many years ago and I can tell you that it is one of the finest bikes produced during the 60's. ,ROBL,


Swarbrick Chambers,Friday 17-Nov-2000 15:48:31,205.232.94.151 writes,Anybody got any info on the Swarbrick chambers from England? I think they're replicas of the original TR500 chambers. Since the TRs had more radical porting than the T500 what kind of gains can you expect using those chambers with stock porting? As per everyone's advice (thank you) I am keeping the motor of my racer stock with the exception of chambers and jetting and concentrating on the handling. What pipes are best for the stock porting what kind of mods need to be made to fit the pipes and what are the costs? I know we've talked about this in the past but I want to get definitive answers before I spend any money so one more time if you don't mind. As there have been no answers to my posts about used chambers I fear I may have to buy new. I spoke to Martin at Crooks Suzuki in England via e-mail and he said he's putting together a catalogue of T/GT500 parts over the next month. If you want to get on the list e-mail him: martin@crooks-suzuki.com.<BR>,Kris Larrivee,
Re: Swarbrick Chambers,Saturday 18-Nov-2000 19:05:29,195.92.198.85 writes,Kris <BR><BR>I am told that Swarbrick has got the equipment to make a range of pipes plus tapered headers. In fact I plan to get some made soon. He normally supplies cone kits so that you can fit them to the bike to your requirements. I have had some mild port tuning done since the T500L barrels I have are the later type and they respond very well to sensible mods for the road. You must select the chambers according to your port timing figures. Its a common mistake to make the pipes too short and the motor only comes on the pipe high up in the rev range and you loose more low end power than the stock exhaust pipes. There is no fixed solution to this since anyone who knows what they are talking about will tell you that the pipe must be matched to the engine. The main parameters affecting pipe design are of course port timing and you can make some very significant gains with pipe/port/carb mods to lift the motor power more than 10 BHP without making the motor too peaky. I have been advised to have the pipe peak at about 6800 Rpm which is about midway between peak torque and peak power revs (about7400) with my state of tune.<BR><BR>Hope this helps<BR><BR>Phil,Phil Collins,

Dumb question time.,Monday 13-Nov-2000 01:21:02,64.193.239.137 writes,I've gotten to the point where I have financially commited myself to complete my '68 T-500 no matter what (as I could have most likely bought 3 for what this will end up costing). I am currently installing an engine from a '74 in place of the original. (Right barrel only came off after using a hammer left piston had exploded installing shrapnel in the main bearing case had numerous cracks around the drive sprocket cover). My questions are these does the '74 use the same petcock as the '68? The '74 did not have a petcock when I grabbed the engine for me to compare. As near as I can tell (please correct me if I am wrong) the '68 is a vaccum operated petcock petcock only opens when there is engine vaccum. there is no shut-off position on this petcock and has a third tube running to the left carb. The '74 appears to have only one tube on the left carb. Am I correct in assuming how the '68 petcock operates or am I missing something altogether? Also the '74 carbs have two tubes running from the bottom of the bowl to nothing. What is the purpose of these tubes as they were not in place on the '68. One of the tubes was pinched flat under the oil pump cover - hope this did not cause a problem to worry about.<BR><BR>Second question I have the case split and the engine in many pieces and am in the process of replacing all of the seals I can. I have read about failure of the righthand main seal causing the engine to suck trans oil into the combustion chamber. Needless to say I assumed that the seal being referred to was the large o-ring located around the main bearing. After ordering seals by part description I am guessing that I have assumed wrong as the seal appears to cover the bearing face. Can this seal be replaced without disassembling the crank? I didn't feel like prying and poking without a little insight. Also it appears that I have ordered all of the seals for all of the bearings. Is the righthand seal the one most prone to failure? How prone are the center ones? If failure is not that common on the center bearings I will most likely pass on replacing them at this time as I assume the crank will have to be disassembled to do this (which sounds somewhat expensive and the engine does not have that mnay miles on it). <BR><BR>Thanks for all the help that has been sent my way over the past months.

First I am guessing that there is a third tube on the lefthand carb for the petcock and I need to find the port? I didn't see one casually looking at it. Second how does on determine when the middle crank seals are bad? I am assuming if the right goes out there will be much more smoke coming out the right exhaust and if the left goes there will be traces of oil behind the rotor. What happens when the middle goes out? I am assuming that something will happen to the bikes running ability in that the downward force of the piston will force the fuel/air mixture into the other side of the crankcase rather than into the combustion chamber?

A Fruitless Search,Friday 10-Nov-2000 18:15:28,205.232.94.136 writes,I posted a couple of weeks ago about an ongoing search for a T500 dragracer I kept hearing about. I finally got a name and an address (sort of). The bike was supposed to be located at a farm on the top of a hill and the last name was McNeely. After driving around the area for an hour and trudging through mud and cows--- asking everybody where the McNeely farm is I was about ready to give up. The last farm I stopped at this ninety year old woman told me that there had never been a McNeely in the area but there are a lot of Keneelys around. She directed me to the nearest farm and off I went into the rain again but not before she offered to give me something to eat. Very nice of her. I knocked on the door at the Keneely farm and there didn't seem to be anyone home but the barn door was wide open. I had to see if she was there but it was dark. A voice from behind asked if he could help me. I explained to him that I had heard he had a T500 he might want to sell. He said he did have that bike but sold it this summer to the Kelly boys up the road. More directions and another trip to yet another farm brought out only Pa Kelly who told me that yes his boys did have a motorbike but lost it this summer when the barn burned to the ground taking alot of hay and some livestock with it nothing survived. He said they hauled everything off to the dump after the fire. I thanked him ran back to the truck to get out of the pouring rain thought about the long winter ahead and wished I could get this T500 racer project moving. ,Kris Larrivee,

NEW wires on OLD coils,Tuesday 7-Nov-2000 09:55:47,12.84.177.217 writes,As most of you know I've been asking everyone lately how to make my GT 550 go faster and handle better. I thank everyone for their responses. A "friend" of mine who was supposed to be knowledgeable gave me some bad advice. When I told him I was buying new ignition coils he told me I could just replace the wires. He said they were attached inside the coil just like they are on the sparkplug boot; with that little scew thing that goes up into the wire. Well I carefully twisted and pulled the wires out of the coils. (The coils had metered out good and the coil bodies were in excellent shape). When I finished the first one I noticed that the actual wire core was still attached down in the coil I had just pulled the insulation off the wire. I had also ruined the coil. Since I am an Industrial Electrician and I had to work this past weekend I took the coils to work and started to investigate. With the combination of a razor knife hacksaw drill and soldering iron I was able to get through the plastic where the wires attached and see that the old wires were soldered to a tab on the coil. I cleaned up the tab drilled out the hole along the side of the coil for clearance and soldered in my new low resistance wires. I then sealed everything up with RTV. I got better with each coil I did. (The third one looks much better than the first) I'm almost tempted to buy more coils and tear them up too so I can perfect this operation...nah I guess not... Anyway if anyone wants to renew their sparkplug leads cheaply I believe this will work. Just don't cut down into the body of the coil. ,Todd T,

shifting shaft situation,Saturday 4-Nov-2000 20:50:26,4.54.43.244 writes,I am working here and there at restoring a T500K to street running. Today I tried to have a look under the left engine cover and discovered to my dismay that some dumbass had welded the shifting lever onto the shifting shaft. This of course makes it impossible to remove the engine cover so one cannot even replace the front sprocket. Sigh. So I ground the weld off and found that this shortsighted individual had also drilled a hole through the shifter into the shifting shaft and driven what looked like a thread chasing screw with no head into this hole and then welded a pile of pot metal over the whole mess to hold it in place. Ah the woes of 2nd (3rd? 4rth?) ownership. Anyway I finally got the thing off but only after much weeping and cursing. Behind the engine cover there was a nice surprise of dirty slugde dead spiders and other sundry nasties. I just thought I'd tell my story to help me move on. Thanks!,Matt,

NOW you get to remove the clutch cover to replace the shifter shaft AND<BR>whatever other neat "surprises" you find on that side of the engine. My experience with ALL twin and triple Suzis is that if you don't Loctite that shifter lever pinch bolt it WILL back off and then you start chewing up the splines on the shaft every time you make a shift. Your other choice is to put a box end wrench to the pinch bolt every time you're near the bike. Loose pinch bolt/chewed splines is probably what happened to your Titan way back.

I am getting the cylinders bored .5 mm over by a great little old auto machine shop here in Raleigh NC - for only $55.00 total.

Yes I'm a big fan of electronic ignitions because of all the things mentioned in that earlier post...mainly consistent spark timing because of no wearing/rubbing parts.

Although the flexy flyer frame of the H1 is a MEDIUM DISADVANTAGE H1 a talented rider can negate some of that disadvantage.<BR>Secondly the H1 engine uses more radical porting<BR>and I believe a little higher compression ratio. I believe they also have more transfer port area than the GT550. You Kawi guys can shed more light on this part. BIG ADVANTAGE H1 !! Your GT would need serious port work to even approach stock H1 porting.<BR>Thirdly the H1 has CDI ignition so has very hot and CONSISTENT spark compared to GT550 with points. BIG ADVANTAGE H1 !! You have taken care of one part of this H1 advantage with the Newtronic but I believe you would be wise to look into uprated coils/spark leads to get full benefits of Newtronic.<BR>Fourthly (is there such a word ?) the H1 has stock exhausts (69 through 71 models) which are really thinly disguised high performance expansion chambers inside an outer skin (and very lightweight compared to 550 pipes). The GT pipes are very conservatively designed...more for torque than HP (and HEAVY). BIG ADVANTAGE H1 !! You are taking care of some of this with your chambers.<BR>Fifthly ?? The H1 has "stuffed" crankcases. In other words the crankshaft is designed so that<BR>there is very little clearance between the crankwheels of each bottom end and the cases themselves. This gives much faster throttle response because the fuel charge is easier to compress (smaller volume to compress) and the charge moves faster through the crank chamber into the combustion chamber. BIG ADVANTAGE H1 !!<BR>It would be VERY expensive to overcome this <BR>disadvantage on the GT550 if it even COULD be done.<BR>As I've said before the H1 is a much more "intense" bike than the GT550. It also has a much shorter durability "fuse". BIG DISADVANTAGE H1 !!<BR>Again as I've said before the stock GT550 will STILL be running and piling up miles when the H1 is having its engine rebuilt for the second or third time.<BR>At the end of all this after you make all your mods and do all your tuning you will probably<BR>be able to scare the bejeezus out of the odd H1<BR>but most H1's STILL on the road are USUALLY ridden by guys who KNOW how to ride them in the<BR>"Stoplight-to-Stoplight Grand Prix" and they will probably be at least 1 bike length ahead of you at the next light. A fifth gear roll-on at say <BR>40-50 MPH will be a different story assuming stock gearing. You should be able to blow their doors off up to about 70-80 MPH but they WILL<BR>catch you eventually once the H1 comes on the pipe at about 6000 RPM.<BR>As to jetting: start with 2 sizes larger than stock and use one heat range colder plug i.e.<BR>B9ES. Don't bother buying platinum plugs for the<BR>tuning/adjusting period because (hopefully) you WILL foul one or 2 sets of plugs until you get things just right instead of burning up a piston. <BR>Take those plug readings and adjust accordingly<BR>for rich or lean conditions. Try to keep all external conditions constant i.e. don't change jets AND adjust timing for the same plug check.<BR>Set the timing leave it alone and concentrate on the jetting.

The 380 has true pure Schnuerle porting with no auxillaries or boosters and the ports are quite small in height and width. I got a great idea from examining my GT250 which basically had the same porting but with one major difference: the exhaust port had 2 small ports on either side near the top to effectively widen it without the risk of losing ring support. I know how to take a hint and drilled two 1/4 inch holes on either side of the 380's exhaust port the tops of the holes being equal with the top of the exhaust port. Next I used my Dremel and a carbide bit to drop the bottom of the new holes 3/4 of the way down towards the bottom of the exhaust port and slightly ovalled out the tops of the holes. Next I drilled two 3/8" holes in the piston skirt on the intake side just on either side of the<BR>intake port but so as not to fall in the ring gap areas. Then using the Dremel I cut two troughs or grooves if you will in the cylinder walls that were even with the tops of the tranfers and the bottom of the grooves<BR>were even with the holes in the skirt at BDC. Basically I added 2 booster ports angled right at the plug and widened the exhaust with webbed holes to support the ring. Next I had the head milled to set the squish at .040" and went up 2 jet sizes on the mains used Uni-Filter foam on the stock filter cages and re-packed the silencers. Talk about a difference.....It would do roll-on wheelies in first just snap the<BR>throttle open and enjoy the view of the sky! The stock 380 would crap out at about 7K but this one would pull hard all the way to redline and you didn't need to take it that far to get all the thrills you wanted. I got the booster idea and drilling the holes in the skirt from Aerimacchis and RDs that I had seen back then.
