Working on a 2006 CRF250R that needed valves shimmed. Shimmed intake and exhaust to spec in manual and timed and wouldn't even get a pop. Checked spark and had very random spark. Rechecked timing and was good. Checked ohm readings on stator and was found odd numbers compared to manual. Replaced stator and now I have consistent spark every kick. Still am not getting even a pop or sputter. Tried feeding starting fluid straight into the carb with no luck. Any ideas for me to try next?

I’d start with a leak down and go from there, just because the valves are in spec doesn’t mean they’re sealing all the way. Those bikes are notorious for eating valves.

Will do. Actually just bought a leak down tester so I will put it on its maiden voyage and report back. Thanks
