joker149999 Posted June 17, 2007 Report Share Posted June 17, 2007 I have 2001 bike, i have removed the tor's i have k&n airfilters with no air boxes i run delta 4 race reeds a high compression head, ported and polished, long rod crank, .80 thousands over piston's and t-5 pipes, and here is my question i run my bike 32 to 1. It misses on the left cylinder above a high idle. I've checked and cleaned the carbs, swaped the plug wiresand plugs, checked the reeds for air leaks and it seems to have good compession on both sides and it runs the same. Does anyone have any suggestions? Thanks for the help Quote Link to comment Share on other sites More sharing options...
Kama Posted June 18, 2007 Report Share Posted June 18, 2007 Do a pressure test for the lower end. I had this at one time and I had blown seals on the bottom end. Quote Link to comment Share on other sites More sharing options...

Sounds like a pressure test is needed. Determine whether or not the engine has a leak. If you have covered the other basics, this is next.

joker149999 Posted June 19, 2007 Author Report Share Posted June 19, 2007 ok answer me this then if i have a blowen seal or a cracked case why does only one cylinder cut out off idle? it's a open crank case there for it should affect both cylinders. i guess i just don't understand Quote Link to comment Share on other sites More sharing options...

I am not confident that is your problem though. Sounds like carb sync to me. Pull your air filter and peek in and see if the slides move in unison with each other when opening the throttle. Adjust the adjusters on top of carbs as needed to make them open and close the same. Always best to do this with idle screws totally backed out. If that does not fix it, should be pilot jet on the LH carb. Take the bowl off and make damn sure it is clear. VERY tiny hole in it.
