Hi, I am a new member rebuilding a vintage ('75) road racer. No not a MC, a sports car :) It is 650# DSR class racer powered by the Suzuki 2- stroke. I have...
Tony would like to learn the whereabouts of any former and current owners of bikes/chassis that he's built. I think there has been mention that someone on the...
Sorry for the slow response John, I'd certainly be interested in seeing any pics, particularly of the TR. Thanks, Brian (Sydney) ... From: John McCann To:...
Hi Brian, I have posted a few pics (photos, McCann) RE my TR750, actually all I have is a barrel and head. The barrel has a broken sleeve from a broken rod,...
I just had a thought about the flat track guys using carbs on their TL1000 Suzuki racers that are normally running fuel injection. It seems like they'd really...
Problem is that the stock TL1000 computer does not allow for different maps. The most you can do is to tune the standard fuel map every few hundred rpms. This...
I would suggest using a Megasquirt, you can tune it to your hearts content and if there are not enough options, you can code your own. I have which I am...
Hello; My neibour uses a Megasquirt on his blown Suburu engined drag bike and he is also putting a CBR EFI on an old SOHC 750. I think he is using a megasquirt...
Hello John, I didn't expect that the stock Suzuki computer would let them do anything like that. My comment was more about the possibilities of allowing...
I have it on two racebikes, right now they are only controlling fuel. The plan is to finish the fueling map on the single, and then add in the ignition...
Michael, It is all beyond me, I'm a vintage man :) John ... Hello John, I didn't expect that the stock Suzuki computer would let them do anything like that....
John, Actually, you can tune the stock TL ECU at idle, 10% throttle, 10, 25, 50, 75 and 100% throttle. If you have a problem at a throttle position between ...
Hello, I'm going to fit 72mm gsxr pistons in a cb750 sohc cylinderblock. According to Phill Irving I should have a clearence of about .20 mm, but materials...
... Not so much materials, but piston design has changed radically. if you set them to 0.20mm you'll hear it rattling 10 km away. Even 0.10 mm is too wide for...

Thanks for the response, I'll go for 0.05, assuming that Yamaha pistons (which go in the V8?) are also ART and shall not differ that much from the yzf/R...
... Always better a tad rich than lean on run in - remember that you will probably have to run the outside cylinders with different jets to the inside...

If any of you GearHeadz should get a chance to take a whack at this, I'd appreciate it. See what you think... I don't know how many of you have the test...
D.M.Co., Ian is right on this for maximum clearance but it depends where you measure it and that is not likely to be at the bottom of the skirt. Along with...

Ian, Marin, thanks for your responses. I Understand your concerns, Marin, but this engine has allready run good for 30 years with a 1000cc kit (70mm Japauto...
willem, It was long ago and we beat a lot of 1000 cc Kawasakis with ours but indeed, the breathing limited what we could get out of the SOHC Honda. Even with...
Hi all, Looking for a bit of help in finding suppliers of valves for my racebike. It's a kitted 93-95 Kawasaki ZXR750R (aka ZX7R), and the valves are getting...
Kibblewhite Precision Machining, www.blackdiamondvalves.com, makes them in standard and oversize. They are what KPM calls their "White Diamond" valve, made of...
I was once given advice that, as a general rule, when assembling race engines, I should automatically go for the manufacturers bearings with the greatest...
... Bearing clearance is critical in high speed motors - you'll need to get it within 0.01 mm if you are revving it hard. You'll definitely need to use the...

it is not that you should go for maximum bearing clearences with crankshaft or Conrod brg. the minimum oil film thickness is required to be maintained.(about 1...
Oil pressure gets the oil to the bearing. Plenty of bearings establish and maintain hydrodynamic lubrication with simple non-pressurized oil delivery methods....
this is not an answer, obviously, sorry, obviously... I am interested in machines that do this kind of testing: what kind of electric motors are used for these...
Some searches on Smokey Yunick's Smoketron may turn up some info. It was used for measuring losses of NASCAR engines. If you can't find what you need, I went...
