I had my mojave riddin on wed, and that night i was goin down the road in 3rd, half throttle and it packfired, and stalled. Now when i get it started and try to run it, i'll give it some trottle and it won't rev very high and then it will all-together die. I checked the spark plug and it's fine. I was wondering if anyone knew what might be going on.

 

Go get a compression gauge and check cylinder compression. If you get anything below 100 psi, you need to open up the top end and look for any obvious damage. Also, check cam timing - the cam chain might have skipped a tooth or 2.
