FASTOYS Posted December 21, 2009 Report Share Posted December 21, 2009 hey thanks that makes me feel better, i noticed that your from oklahoma, im from kansas and need some advice on my jetting, i just broke the motor in and have about 1 tank ran through it, i think im running rich, i have stock carbs, port work on cylinders and cases, cool head, with 20cc domes, +4 timing plate, oh by the way its a play/dune port (mid), vforce reeds, kandn filters without air box, right now im running 350mains and 27.5 pilot, its been around 50 degrees. whatcha think?? If your in Kansas its like 24 degrees here right now. Who ported your bike, might ask them? I would say stay with the 350s till it warms up a bit or start taking it down SLOWLY till your plug chops say your good. Cold weather is Taboo for new 2 stroke motors!! As for vibration, may want to check mounts, check flywheel, and check carb sync. Quote Link to comment Share on other sites More sharing options...

broncbob Posted February 2, 2010 Report Share Posted February 2, 2010 You need to have all the mounts on there. Quote Link to comment Share on other sites More sharing options...
AKheathen Posted February 2, 2010 Report Share Posted February 2, 2010 the things to look at are carb sync, misfire-like pickup gap/flywheel, and compression imballance. if the porting specs don't match, or chamber size/squish is off, it'll throw out a pretty good vibration, especially free-reving...
