Went out rideing this weekend and got a few miles into the woods when my bike started backfireing a missing. No big deal, thought it may have just fouled the plug. So we stopped and changed the plug. It looked good but changed in a new one since we had bike apart. Put every thing back together and it fired up and ran fine. then about after an other hour on the trails it started missing and backfiring again put would clean its self out. So we kept going. Now when I would come into a corner I would clutch and let off gass and it would stall like I had hit the kill switch. Let clutch out restart keep going. After I hit a big long stretch of Whoops the thin g just died and never started again.
