Yeah so I picked up a 2000 CR125 yesterday, ran great. Started up first kick. Brought it home, started it again to show my friend and it started just fine. I pull it out this morning (changed the tranny oil, and topped of the radiator and cleaned the filter). Started up just fine (I think 2 kicks). Not expecting much anyways since the seller said there is only like 5 hours or so left on the piston/ring.
I took it out for a ride 5 minute ride today in the orange groves, warmed it up first and it ran great. Very fast, lots of top end power. No weird noises, nothing but just running a little rich. I ride it home and shut it down. Come back out 2 hours later to ride again, and it wouldn't start. I have been through a lot of stuff, but I just can't figure it out. I need help on this one. So bear with me, because I am explaining it below.
-------------------------------------------------------
I changed the spark plug. When rested against the head you can see a nice blue spark, you can even hear it. So it has spark, and it looks strong.
I took the carb apart and cleaned it. It looked very clean but I wanted to rule that out so I cleaned it anyways.
It has vforce reeds. I took the reed block out and inspected the reeds, reeds look to be in good condition.
Other then that, I took a compression test, came out around 110-120psi... pretty low. But it ran fine 1 hour before, and the kicker felt the same compression wise.
Sooo as a last resort, I tired bump starting it, just to see if it starts and its not because of weak compression.. and still no start. Motor turns over just wont even atemp to start.
WHAT GIVES??
