Malagutia goes for 20 min whats the problem
Hi,
If the engine will run for twenty mins then just stops it may be worth checking the air vent to the fuel tank. Dirt bikes often have a small plastic tube fitted to the petrol cap to allow air into the tank. Sometimes the tiny hole in the fuel cap ( Which most bike have) gets blocked and the engine will run until such time as the vacuum in the tank stops fuel coming through. Got to be worth a check.
Cheers Stan
Crank bolt keeps undoing
Try some Loctite on the threads:

The blue allows disassembly with common hand tools.
The red usually needs impact tools to undo.
Available at auto parts stores.
The crankshaft sprocket (for the primary chain) on Harley's use the red to secure the nut, as this is something you don't want coming loose on ya.
While stopped when i rev the engine the speedo jumps alkl over
It sounds like you might have an electric/cordless speedo, what could cause it to jump while at a stand still when you rev the engine could be a bad connection in the instrument cluster where the voltage from your tachometer is affecting your speedometer. Try to see if any of the speedo or tacho wires are cracked, burned, melted, or just simply not grounded. Like I always say, badly grounded wires can create unmentioned problems.
