So I finally got the 650 running today after spending all weekend grinding the new valves in. It runs pretty well as long as the choke is on. Take it of a little and it stops. It has some cheep cone filters on so obviously getting way to much air. I plan on getting the k&n air filters for it they look cool 1 filter covers 2 carbs. But I'm going to have to jet it. Any advice welcome.
Will post a link to you tube when I work out why my phone won't upload it.
