I've run this new 65cc Arisal kit about fourty miles so far on my 00' Targa. Before the bike would get alittle jerky here and there. Larger jets where suggested and seemed to help. Now with the new kit, 66 jet, stock carb, estroil exhaust, it still(if not more so) is jerking around.
Usually, off the bat, it has trouble going from first to second. Then at high speed (rpms) it bogs out in a jerky kind of way. It goes in and out fast until I throttle down and find a nice RPM it likes. Uphill I can open it up and it's not so bad...but downhill fast it's a jerky jerker.
I did a plug chop and it wasn't a rich brown, it leaned more on the grey side. I changed the tranny fluid and it struggled so after it was warmed up I let alittle fluid out while standing on level ground...that seemed to help it run smoother. But then jerk-a-jerk-a-jerk it was back occationally.
New clutch? Does running too lean in this 40F weather cause it to run rough? Smoother with a 68 jet maybe? These are the questions I have for you guyz with experience.
Let me say jerky a few more times...jerky jerkin' jerky jerk. Thanks.
