Hey guys, lurked and searched the site over the years but have not had a real reason to post till now...
I have a 2009 CRF 450r that I can not to get to start. It ran perfectly this spring, just a little hard to start which sounds typical for an 09. The last time it ran I had a really tough time getting it started, but after it did start it ran perfectly. When I tried to start it again, it just plain wouldn't start and has not ran since.
I checked the valves and the exhaust was a little loose for some reason so I had them adjusted to make sure they were in spec.
It has great spark.
It has great compression.
it has 50lbs of fuel pressure
the condensor holds 12v
It had a cylinder works 478 bbk and fast head with stage 2 hot cam and a dobeck auto tune programmer. (This is my snowbike in the winter). I unplugged the programmer and no change.
Is there a way to check if the injector is spraying? Pull it out and kick?
What else do I need to check?
