So I rode my 2007 DR650 about 5 weeks ago and it ran great. Then went to take it out the other day and it barely runs. It only idles if the choke is on. Dies immediately if the choke is switched off. Also dies if I roll on the throttle at all. I can sometimes get it to rev, but it pops really bad and gets really hot. I took the carburetor off and it wasn't dirty, but I took the jets out and sprayed cleaner through them anyway, and through the rest of the carb. Also put new spark plugs in and am using fresh gas. It didn't fix it and it still runs like crap and not rideable. What could have caused this? Am I not thinking of something else?
