kx85 stickers and formula 80 . On a more serious note, they're just over bored kx85s. Not sure if you can use a kx85 cylinder though. kx100: 52.5 x 45.8 kx85: 48.5 x 45.8.
For one lap. Then you get to push it. That happened to my big ass a couple of times. Better to ride on the parking lot. "I'll run it extra rich." seize "I'll feather the kill switch." seize "I'll ride a child's bike that's made for short bursts of wide open throttle at wide open throttle for extended periods on straight-aways and..." SEIZE/trade
yeah if you gear them right you won't blow them up. make sure to run like 30:1 oil and use Castrol TTS, I've seen that oil prevent some seizures that could have been nasty. Short bursts of power stuff can be related to ignition timing.start the timing out at 0 and if you look on the spark plug there is a burn mark on the electrode, the one that's connected to the threaded part not the one with the ceramic insulator on it, and the burn mark should cover like half the electrode and its a kinda beige color. if the burn mark goes more than halfway, it starts from the outside and moves in, that means you have too much advance. if too short you can add like 0.5 degree of advance at a time to get it right.
Nick Where did you learn all that ? You sound like a expert. Contrary to popular belief , Mini Motocross engines are not built for short bursts of power , but instead to be held wide open in deep loam for long periods of time. The biggest cause of problems with them is the oil people use,Manufacturers oil And 927 Is junk and will kill them in no time. Due to the porting of this particular bike I doubt if it would be competetive with the Mini's , Unless you replaced the Cylinder . ANd Yes the 85 Cylinder will bolt right on.
