Hi guys, I have an 04 CRF I had the water pump seals and the valves checked two rides (approx 3hrs running ago). I Rode it two weeks ago and it started and ran a treat. I did fall off though and snap the hot start cable. It ran fine anyway so i finished the day. I went away for two weeks, went to start it today and it didn't want to start. I bumped it no probs and it ran perfect all afternoon (approx 1.5hrs). I did manage to start it once hot with pliers pulling the hot start cable. But other than that bumped only. It ran perfect: no oil loss/smoke, no coolant loss and no power loss. The thing that is baffling me is that the kick start doesn't seem to crank up compression like it used to (I would kick it around 3 times then it got stiff-ready to start). Instead now it seems to be light/easy to kick all the time. It does not seem to build up. Any ideas what it could be? Maybe exhaust valve clearances/not shutting properly? Any ideas would bE great thanks. Cheers!
