Helpppp...2002 Yz250f

vmf214 · 09-10-2007, 05:23 PM

I just purchased a 2002 YZ250F, It is my first bike I have been sharing my son's 1979 XT500. He was able to kick it over with no problem when we test rode it. it runs really good. The problem now is that it is extremely hard to kick now we haven't been able to stsrt it at all by kicking it, we had to jump start it, any ideas on what might cause it.

Thanks Jim

wat do u mean extremely hard to kick? do u mean, requires lots of force or takes lots of time to start? let me know then i will start throwing out some troubleshooting.

It takes alot of force to kick I can stand on it and it wont move, When I hit the compression release it is easy to kick

you do realize there is a starting drill dont you?

also on these bike if you want it to be easier you can buy an 03 and up exhaust cam to install, it has auto decompression and just drops right in!

I didn't know about the starting drill that is interesting I will try it tomorrow and see if that helps. Thanks I will keep you posted.

man, i wasnt even reading everything and didnt see that u had a yz250f. all i saw was yz250. ya, i can tell u from experience that 4 strokes suck to start. i have a rmz250 that is completely rebuilt. its a new bike. after sitting for a week it takes 10 kicks to start compared to a 2 stroke and maybe 2 kicks. anyway if i stall it out, ill be kicking for a couple of mins to get it started. ya, the auto-decompression cam makes it so much easier to start, i dont really kno y yamaha stuck with the old design. the starting drill can help out but the truth is, no one's starting procedure works for anyone else or their bike.
