[QUOTE="Canadian Dave, post: 644290, member: 16102"] It sounds like you're working your way through some typical problems with a used bike, fun eh? A few things to add. If the stock piston wasn't replaced with a Wiseco piston I'd consider doing so. I wouldn't re-ring a stock 220 piston. The stock 200 piston is of excellent quality but the stock 220 piston can crack if the engine is worked hard, modified etc. General rule of thumb is to replace the stock 220 piston when you rebuild the top end. Not all pistons are bad but there are some and you don't want it to be yours. If you followed the factory shop manual to the letter when you reassembled the top end be aware that some manuals wrongly identify the left and right sub port valves resulting in incorrect timing. For more details see the Justkdx web site. Check out the article on removing the top end as well paying particular attention to the discussion on properly supporting the main kips shaft when removing the nut on top. You'll need to measure the carb and determine if it’s a 33 or 35mm carb before jetting. From your results I'd say it’s a good bet it’s a 33 though. [/QUOTE]
