That sounds very wierd that you would have to re-ring that already. Both of my bikes go a lot longer than that...


It's almost obviously your problem having lost all your compression but just seems very odd to me.. but who knows.



Either way hopfully the new rings solve your problem!! Good luck

Maybe its running lean and you destroyed the rings, Maybe its too rich and they washed out?

If its running right they should last a lot longer

Could jus tbe faultly rings....lemons do happen....

[nathan]

it was runing prety lean fro a while. so i adjusted on my carb and got it rigth now . but may be thats what caused it because ive never had rings were out tgis quick

[nathan]

crank bearing and ever thing was good. my dome was black and had carbon on the front and was clean as could br in the back is that normal?

[nathan]

i put the rings in to day and it fixed it dont know how long it will last but she's good for now
