I'm going to try to make this questions short. And thanks for the great information as always guys.
I rebuilt my carb and I have a assortment of all kinds of jets that were handed down to me when I bought bike. I have no idea what Jets were in it before the year down. Now that everything is back together, the bike runs great other than it surges while decelerating in gear. I rev up 1st through 3rd say, I let off the gas completely and while decelerating the bike surges every second or 2. Not lagging like it's gonna die. Surging or lunging like little bursts of power the instantly go away. Assuming I have no air leaks, because the bike ran great less than a week ago. I can test that later. But if it indeed is because of jetting what would cause that? Since there's no throttle on the bike at that time I would guess it's the pilot jet. Right now I'm running a 58 pilot jet second needle from the top and a 165 Main. I'm at sea level essentially and between 70 and 80 degrees.
According to the jetting chart in this forum at my altitude they recommend stock settings. I'm One Clip leaner on the needle and one size smaller on the main jet. I've heard most guys are running that and I might be going into a little bit of elevation tomorrow.
I have a pro circuit to platinum pipe comma a power Dynamo ignition, a reed spacer and FMF silencer. I also have the decompression valve that goes on the cylinder wall not the one on the top of the head. I'm told this does result and slightly lower compression but I'm not sure if that will have much of an effect on the jetting.
I really have no idea, but if I were to guess I would say it's a lean situation. And yet the stock pilot jet is supposed to be on the rich side and now it's even warmer outside... I'm going riding tomorrow after work and I'm hoping to get in one pilot jet change before we leave and then I'll be stuck with it for the night. Advice? I have a 55-60-62 pilot, and the 58 installed now
