lineaway Posted August 13, 2014 Report Share Posted August 13, 2014 There has never been a parts list for the `02. Quote Link to comment Share on other sites More sharing options...

lineaway Posted August 13, 2014 Report Share Posted August 13, 2014 I understand you just rebuilt the motor. I would start with what jets you have in it for your elevation. The `02 also had mag cases, so the idea of a leak test is in order. Did you do the rebuild or someone real familiar with the pro. The cases were different on the `02 so the center gasket could be suspect, so was the clutch cover gasket. The `02 had a crazy amount of problems, which can be worked out with patience and lots of investment. That is why they never made a parts list.

There was an engine parts manual published for the 2002 Pro engine (I have a copy) but not a chassis manual that I'm aware of, much of the engine manuals you see after that were a modification of that original manual. Burnleytazz has a optional wedge-type carb spacer installed on his engine. You could obtain one from your dealer and it was used to tilt the carb up a little to gain clearance between the carb float bowl and the top of the engine cases. I made one for my JTR370 when installing a 28PWK and it was a common mod for the Keihin on the early Pro 250/280's. Jon Quote Link to comment Share on other sites More sharing options...
lineaway Posted August 14, 2014 Report Share Posted August 14, 2014 Jon, this guy lost his motor last year and just now finished it. I doubt that it is the spacer causing the ping. He was chasing timing and now the intake. Either he has an air leak or a carb issue. Just my two cents. 1 Quote Link to comment Share on other sites More sharing options...
copemech Posted August 14, 2014 Report Share Posted August 14, 2014 or it's still on '02 jets with alcohol induced fuel, just a thought. Quote Link to comment Share on other sites More sharing options...
burnleytazz Posted August 14, 2014 Author Report Share Posted August 14, 2014 (edited) Jon, this guy lost his motor last year and just now finished it. I doubt that it is the spacer causing the ping. He was chasing timing and now the intake. Either he has an air leak or a carb issue. i bought the bike last year knowing nothing about trials or gas gas. When i bought the bike it was overheating after 20 mins so bought the following water pump repair kit head o rings rectifier (which it never had on when bought) Piston kit size b air filter It was running without a rectifier witch was the problem. after installing all these new parts it was fine for bout 100 hrs then top end bearing went then bottom went so 3 months ago got a new crank bearing rod and another top end bearing. Due to work i only got piston rings this week thinking everything would be okay. but upon starting it was knocking which at first i thought was piston slap then i didnt know if it was pinging/detonation. but now thanks to jse/jon i now know its defently piston clearance nikosil coating has worn through. but i started this thread cause i am getting detonation due to an air leak and wondering about this spacer also u made a good point about the casing becuase looking at now its not flush together. again when i recieved my gasket kit it had 2 crank case gaskets in it thnx everyone ur info is appreciated Edited August 14, 2014 by burnleytazz 1 Quote Link to comment Share on other sites More sharing options...
