250F Hard start after rebuild? 2007 CRF250R

Haven't even had a chance to look at it other than what my dad told me. Cant even move my left leg because of the muscle and stitches.
 
Shite :cripple:still you are young and will heal quickly!
Ask your dad to make a list of parts for the rebuild and get on eBay while you're on your ass!
2 weeks from now you'll be rebuilding it:ride::thumb:
 
So after a good recovery, Im ready to get back on the bike, but its still a pain too start and even backfiring worse now. Could it be that It needs a new timing chain?
 
Yep, or so I thought. About a week ago I rolled my quad doing about 45, I am in disbelief how I didn't break anything. I'll try to get pics up asap.
 
I've been riding since I was 5, and I've been riding the quad I rolled for 5 years. The accident was a freak accident, but I'll admit I wasn't driving like I should've been on a 250 trail quad
 
Bikes roll forward not over.
