idk if you all know the story but ill tell it anyways. right after x-mas i went ridin with my buddies and it started actin up after ridin for bout 2 hrs but i kept ridin for another 2. well i thought i just needed a top end rebuild even tho i just did that summer, well after we did the top end it still did the same thing. i found out it was the crank seals so i got bearings and seals and i just put it together today and it runs great. i took it out and it started in 4 kicks and idled fine.
