Remember me ? I'm the guy who started this thread. Nice dialog,; it seems sometimes my questions elicit this type of exchange, good for all. Jerry I haven't had time to take the measurement you asked about. If the slide is sitting to high is there an adjustment which would correct it. Also someone asked about comp. and electrical. I'm at 210 and all electrical is within spec. That is one of the first things I checked. I have this intake set up because it was what was with the motor when i bought it and he had no problems with it so I wanted to keep things intact. I have carbs from 34 - 40.5 MM I could try, PE, PWK, PJ etc. but no Mikuni. When this bike is warm it runs like a bat out of hell. Anyway like I said it is just hard starting but maybe it is my 60 yr. old leg, but I doubt it as I'm still able to get up and around trees all day long. I have tried a b8es but still the same. I suppose i will continue to pour a teaspoon of mix in the cyl. for the time being. I should post a picture of the pipe I have on it and let you guys try to guess what it is. ( I don't know, but it pulls hard in every gear ). That should be fuel for some more lively exchange. Thanks all Ron ( Gaston, OR. )
