I just became a proud owner of an 08 650 yesterday! I love the bike, but an issue with it, and i am hoping you guys can help.
I picked it up yesterday and i knew it had been sitting a while without use. It had an almost full tank of gas that was stale. I emptied the old gas and put in some new stuff. So it took it out this morning, for my first extended ride and found that its not running good.
The problem is that the engine starts fine and seems to be fine for about 10 minutes. After that, it starts to get really sluggish, and choke out. It appears that its being starved of fuel or air. I could not go above 60 this morning, and was only able to limp home about about 25 or 30 mph.
I have done several things to try and fix the issue. I have replaced all four spark plugs. Same thing. I have put sea foam in the gas and ran it with mixed results. IE, i was able to get her up to 80, but still chokes out at slow speeds and sluggish. :headbang:
I figure the bad gas might have something to do with it. Maybe clogged fuel injectors? Any thoughts?
