hey fellas. been a LONG time since i been here. i have been out of the scoooter scene for some time now. i still have my old dragster and its been sitting for some years now. i pulled it out to get it running again. it starts ok now but when its running its vibrating when ya revv it. i havnt checked the small end bearing and big end yet, i just wanted to check with you guys to see if there is any other issues it could be before i assume its inside the engine. like maybe a binding clutch? stuck roller? one thing that is porbably worth mensioning is the fact my stepdad come off it, as its the external clutch bell nut type i wonder if maybe its bent the spline or something? crank dont seem to have much play from what i can make out. any suggestions guys?
Cheers bud, il have a look tomorrow. pretty sure it isnt the engine, its only done 800 mile since i rebuilt it. got to be something daft. il let ya know what i find
