Doublert, Popping taking off is to much gas but it is not DUE TO THE MAIN JET it is getting to much fuel from the PILOT JET. If it runs good with the 112.5 at 3/4 throttle and WOT leave that one in. The problem is the low range. How many turns is the Fuel Ratio screw out? Do this warm up the motor at least 5 minutes and then slowly turn the Fuel Ratio screw CLOCKWISE until it stops. IF the motor keeps running the PILOT JET is to big. Alleyoop Ok, I'll try that Alley. Btw, I ordered the same cdi from John today, its the variable cdi, Casoli. |

It ran fine just with a 61 BBK, then it ran fine with 61 BBK and 3mm crank. Now on the way to work and home today, it would run ok half the time, then when I slow down and try and keep speed at 50, it would chug and jerk a little, and when I slow down to make a turn then give it throttle to go, it will stutter and pop a little. But when it acts up like that, I give it gas, and it clears up great. Idk...I'll see what size pilot jet is in it now i guess. |

I do notice, that after a long ride, say 15 miles home, I'll cut it off, and try to restart it, and it acts like its flooded, kinda slow to start up, but eventually does. |

have you checked this:

Did the weather change ? Did you change fuel ? have you rechecked the compression ? Is the vac line dry ? I agree something has changed .
Not triyng to over talk Alley , Alley has his carb problems in order .

This thing is getting annoying. |

What's ur top speed with the 61mm and crankshaft? I haven't checked for top speed yet, still taking it easy on the new motor. Right now, i can get up to 50mph quick, I just give it a little throttle, and it gets up to 50 very easy. Right now i've just been cruising going gps 50-55-60. I'm going to waitn a while til I do any top speed runs. I was doing 55 on the way to work this morning in a 55 zone, and passed a Tractor Trailer with ease! I got tired of his tail wind and his speeds going up and down. |

Ok, put the new 26mm RunTong carb on, its fully adjustable. My brother put it on, all he did was raise the needle, and didnt even change jets in it, left whatever was in it there, he didn't even turn the air fuel mixture screw, left it alone too, and it runs just fine. Starts fine, idles fine, no popping or stuttering, no chugging at any speed. If it runs fine now, should I just leave it alone?
