Specials --o-- THOUGHT YOU MIGHT LIKE TO SEE MY 73 t500 Café racer, I live in Kent U.K. and have a collection of bikes but this is my current favourite ..I forgot how much fun old two strokes really are !! The tank is handmade alloy by Custom Tanks and Design in the U.K.,wheels are Akront flanged alloy with s/s spokes. Motor is mildly ported by Stan Stevens racing as I didn’t want to lose the famed T500 TORQUE. I now have some expansion chambers that are being ceramic coated .i am now building a GT500 café racer for my brother so we are keeping the 70’s spirit alive. as these bikes are becoming rarer in jolly old England Great website, keep it up Tim Hart
--o-- Chris is building a T500 based road racer....here is his story...
This is the '76 GT500 I started out with. I bought it off Ebay in '07. It needed a top end rebuild, carb kits, sprockets and chain and some rust removal and shinning to get her road worthy. I road the bike all summer and fall of '07. Then, I came up with the idea to convert her into a road racer and scrapped my other racer project building a Honda CR750. The CR750 project would have costed me 4-5 times what this build will cost. I sold my CR750 tank, seat, fender and exhaust and that should cover the entire TR500 build.
This is a mid point picture of the minor restoration to get her road worthy in '07.
These are pictures i took while tearing down the engine for a rebuild. This is the first time I have rebuilt a bottom end, so i wanted to make sure everything goes back in it's place.
Frame mod to add support tubing. I used chrome moly tubes which are light and strong. This was a mock up step in the process trying to get the placement right.
This is a 1/2 inch steel tube used to mount the tank. I cut notches in the tubing that will allow me to use the stock GT500 tank mounting strap.
I cut and ground off about 5lbs of scrap metal in the form of center stand, side stand, fender mounts, side panel mounts, etc...
These are the mounting tabs for the rearsets I'm making up. They will have holes drilled for the aluminum mounting plates.
Rear fiberglass fender. I used foam from a hobby shop and shaped it until i had the right shape. Then, I covered it and the frame with blue painters tape, cut the fiberglass and added the epoxy.
Rear view shows the fender out of the mold and mounted. I have also made up the front seat mount made out of aluminum flat bar, bent and bolted into the existing frame mounts (I think originally used for the seat grab handle). I had to grind douwn the inside of the two mounts and tap out the hole from the inside of the frame. The original holes were tapped from the outside of the frame where the grab bar bolts mounted.
Side view with the tank, seat and fairing. I'm in the process of figuring out how to mount the fairing in the right place. This was not an easy job!!
Front fairing mount. I used a fairing mounting system from Meadspeed in the UK. I had originally purchased it for a CR750 race bike I was building up, but decided to switch to this build instead. The mounts ended up working perfect on this build with only a few minor modifications.
Here is the beginning of my rear sets being mounted to the frame. The mounting plates are rough cut and will have some shapping and buffing once I get the fit right. I had to make them pretty long to accomodate my long legs and to get into a nice racing position. Getting the right position has taken several tries, but I think I finally have it.

jemco chambers --o-- Kevin Hutchinson is building a serious drag racing GT750....looks good too... Specs: 1974 GT750 L. engine and frame. Ported barrel with 38 mm Mikuni rounds Ignition: MSD Multi-channel total loss Custom flywheel and stock MSD triggers and trigger timing plate Timing is 23 degrees at idle retarding to 20 degrees at 9000 rpm Over rev limit set at 9500 rpm Stock water cooling system Pingel 3 x fuel petcock Motion Pro Coolant Overflow system Swing arm custom built using stock GT ends Rear wheel and brakes from ’78 GS Front forks, brakes/caliper is stock GT750 Tach is Autometer Phantom II mini with shift light Kevin advised he made it out to the AMA Norwalk Fall Nationals during October 08. "My GT750 made it past tech inspection and I made several passes. Here are a few pics of the GT750 (the way it looked that weekend). I continue to make modifications to further reduce weight. Between the front rotor/caliper and battery change, I saved 21 lbs. I am starting a serious effort converting the head to a "squish" design. I made 3 passes, each one slightly better than the prior with the best pass at 12.83 sec/104.3 mph. I know thats not fast but it was a great shake down run and I had a blast."
--0-- I am toying with a T500 cafe racer look....similar to the TT500 Production racer look of the late 60s and early seventies. Just propped some tanks and seat on a GT500 for a prototype......seat is not mounted properly....needs cutout at the back to allow for the tail-light and the tank is just resting there.....but gives me an idea. I probably will use a T500 for the final cafe rather than a GT500....the instruments are lower on the T500 and I will use clubman bars and a 4 leading shoe front drum. Also might use chambers or just Crooks racing bafflles on a standard pipe. Anyhow just toying with the idea right now...and I think the red tank is the go! I actually like that blue oil tank colour with the red fuel tank and seat. Muzz

T500 Sport TT SAIAD Suzuki John Kruger USA --0-- My Next Project................. by Jughead This one will be Code Name Trojan.......... Don't Ask Why.It's what popped into my Mind. Never owning a Sport Bike and Not wanting to Go to 4 Stroke Squid Bikes I've Decided to Build my own Almost Modern 2 Stroke from Pieces of Spare Parts that I have Lying Around.This one will Probably take a Little While to Finish.(It took 8 Years to get something Resembling a Finished bike from my 69 T500) When Finished I'm Hoping to Get something a Little Similar to this.
The Modifications to the Engine will be going on thru out the Summer as time and Money Allows. So far the Mods are turning out Pretty Good.There is a Lot of work to go but this will give you a General Idea of whats going on.
I'm going to Attempt to Install these Stock Yamaha Banshee Reed Cages into the Intakes.I'll be Using the 3/4" Trinity Racing Spacers as the Boxes.This Means I only have to worry about Enough Room to Sink 23MM of the Tip of the Cage into the Cylinder.This itself makes for Another Problem.Getting the Cages Angled to Point Downward to the Intake Port.Hmmmmm OK here we Go. Actually I don't think that the Angle Milling would have been a Big Problem.It just that in Order to Make room the Cylinder Fins Had to be welded up to get a Flat area Big Enough to Gouge out and still have enough Flat Space to Seal the Spacers Against.
OK it doesn't Look Pretty Right Now.I would have liked to have Gotten Them Tig Welded but the welder said that for this Mig was the way to Go.The one on the Left was the first to be done.The Second? well thats what a Cylinder looks like on 190 Everclear. Still not Bad at all but he Used a little more Wire than I really Liked.I may take the lft one back and have him Fill in the Lower Fin to match it up a Little if it looks a little out of Sorts when I have them Milled.Right now the Reed Boxes won't be Attached to the Cylinder by Welding.They will be Bolted so that I can play with different Spacing to see If there is any Changes in the Tune Between them. OK here is the Donor Bike.It's an 89 GS500 E that Had a Clear Title.I picked up for a really Fair Price off of Ebay.
Well the Intake I'm going to use Finally Arrived.Notice no Balance tube/Boost bottle Spigots.Good they are a waste of space.Especially for what I'm Building.Just one more thing to Leak Air.Right Now I have enough to worry with to keep Air tight.
Now It's onto worrying with what I'm Going to stick in the Bores.Instead of Playing around with the Baby Size Stock Suzuki Pistons I've decided to go all out with a set of Old Wiseco .080 ( 2mm).This will take the Displacement from Possibly the Stock 492cc up to 521cc. More is Better I guess? That is until the Pistons detonate or Sieze and Ruin the Bores. --o--
Gary Crump Auckland New Zealand T250 for the track --o-- Coyote is the man...people's choice for his tidy GT550 Suzuki "Redzone", which started out to be a rat-bike but never quite got there.
