Pinking 2008 Rev 250

Featured Replies

I was stuck on a slippery mud climb yesterday and while i was just getting wheelspin revving its nuts off in 4th the engine was pinking which worried me. Any ideas how to stop it? i use high octane petrol and a 75:1 mixture

Check your cooling system to make sure you're not low on fluid. Check to make sure you have the proper plug and have a look to see if it is hotter then it should be. Clean carb to eliminate dirt/water in jets. Check fan to make sure it is operating and radiator is unobstructed. By high octane petrol do you mean racing fuel or just pump gas. I've had batches of "premium" pump gas that were awful.

Gday, after doing all Dan's stuff, check the timing with a light, and if that is OK its time for a decoke. Generally just the head and the piston crown will do. Also clean the exhaust, its also due. (That wont help pinging though).

Cheers,

Stork
