hey guys when i got my 250f used i thought it was awesome but what i didnt kno is that there were many problems. since it was my first 4 stroke i couldnt tell if it had alot of alittle compression but i didnt have much and ended up havin to get new valves and piston. now that i got it back sometimes when i kick start it instead of turning the motor over when i kick it it sometimes goes straight down and makes a sorta grinding noise. i dont think its a problem any help?
