Yea Kawdude..the weather in our area sucks today!! (Peoria Bloomington) What gas are you using--And mix ratio? Are your floats set properly? Both will lead to the problems you are having. Too rich and too much oil in the gas.
kawdude:
92 octane mixed 32to1. As far as I know the float is set right. When I dropped to a 55 I looked at the floats and they seem correct.
Having a hard time with this because I can't tell by sound if the bike is lean or rich. The symptoms appear to be rich. Again, cracking the throttle it appears to have good response buy midway it runs rough. I don't think that it's loading up. Just rough, still has power but could have more. When I first assembled the engine it ran as if jetted correctly. Mid range would hit with a weeeeeeen and would launch.
ruputa:
I believe 32:1 is to much oil. I run 36:1--40:1. Oil shooting out of your silencer is one sure sign of bad mix ratio. Also you can rob a lot of power with to much oil and makes for very hard starting because of the oil fouled plug. A 168 main and 55 pilot jet is fine and 3rd clip is fine also. I would lean out your mixture to 36:1 and check your floats for hole and float height.
kawdude:
When I first started the bike after the rebuild mid range and up was clean. I'm wondering if a over saturated oil filter would lean out the mix???
Not OIL...air filter
ruputa:
Hi kawdude..just stoped by home to stick so food down my neck. If by oil filter you mean oiled air filter...A saturated air filter will increase richness via less air flow. I am sure you need to go to 36:1 - 40:1 gas to oil mix. At 32:1 I am sure you are having major starting problem.
