@fishbulb1992...anytime you re-shim your valves, make sure you check the shim with a micrometer to make sure that the shim measurement is correct...even though a shim may read "192", when measured may only be 1.84. It's happened to me before and it's a PIA!!! I'll post a video with more details.

This is common on CRF's with titanium intake valves. You'll need to have the valve seats professionally cut and new valves installed. Check out CRF's Only (Google us). We use state of the art Newen CNC valve seat cutting equipment. We also offer new heads, head reconditioning, port & polish, valve seat and guide replacement, and full race head services. If you are looking for extreme valve durability we can outfit your head with stainless steel valves at the same time we cut your valve seats.

yo man! my 09 crf250r ate valves up and i took care of that thing so much! oil every 2 rides, filter every ride and i had to adjust the valves every 2 hours! i ride it hard but that is ridiculous! my left intake always went out of spec. i ended up moving to kawasaki

@yamster88

Yeah it will be your valves , you can shim them but usually when valves start to go then its really time for a whole new valves job .. good luck with your bike anyways .. i had the same problem as you , bike would never start from kick but would bump start ..re shimmed and it kicked 1st time BUT the clearence went again after a few hours needing new valves..

@DW0668 haha, I didn't neither. My bottom end just went bad on the bike though :(

[DW0668]

@WaWagasman no lol but i may in the near future

@DW0668 Most definatley. I wish I would've gotten a Hotcam at the time of the rebuild. and yes, I do have Hotcam valve shims. Did you replace your cam chain aswell?

[DW0668]

@WaWagasman i have the same valve set too and there the best, add hot cams valve shims and they make all the difference

My crf250 2004 only push starts the kickstart wont start it and when it is warmed up the kickstart rarely starts it, but starts right up push starting it, could this be the valves????
