I just have one question for all you guys saying you are having problems with your passion motor, Who did your fine tunning? Even if you got a turn-key deal from Jim, you still have to fine tune your jetting. Ok lesson #1 for all first time 2-stroke owners........if your jetting is to fat your bike will bog and have a hard time getting on the pipe and run like a pig, and if your jetting is to lean it will go boom, one jet size either way will make or break a motor. So do you see how important it is. If you say that you and your buddy put some 300 main jets in it and it ran like shit, well thats a no brainer. If your bike is a few years old it can have so many little factors in it not running just right like when was the last time you changed your spark plug caps. I know alot of people don't think about little things like that but you have to keep everything in good condition. I change my spark plug caps about every 6 months. I take my carbs apart after every race and I re-ring my motor about every 6 races. I know everybody is not mechanic and can do all this stuff yourself but if you can't you need to find somebody who can, you will be happy in the long run. It took me a few runs to get my passion motor runing right now it pulls so hard I can't even hold on to it, the bike pulls the front wheels off the ground in 5th gear.
