09 kx250f starting problems

(1/1)

harrisT:
I was riding my bike one days and it started like after 2 or 3 kicks so I came back and parked bike like for 15 min and tried to kickstart it and have no compression what can be the issue.

dave916:
Valve/  check valve clearance

KXDINO:
You need to check valves regular ,we found on 250 f that get ridden hard the inlet valves are buggered at around 50 hrs mark , you need good seats put in the head and keep a eye on the guides as well , air cleaner and oil and filter maintenance goes along way on these bikes , a hour meter is a must , you don,t realize how many hrs you clock up .these bikes are reliable if you keep the parts and maintenance up to them , if you don,t it will cost you .
