Maybe this was the problem?

We picked up a CR125 for my son a while ago and it was a smokin' deal. I did notice it had a brand new front fender and FMF pipe as well as levers and grips. I figure it had some crash damage. Well it sure did and the owner was a little sketchy as to what happened except that the bike was too much for his son. It checked out but the throttle seemed very sticky so I took the bike and popped the throttle apart as soon as I got it home. Here's what I found AFTER I had to fight just to get it off the bars LOL! The whole assembly was packed with graphite, glue, dirt and gunk. A new Moose adjustable aluminum tube and some brake cleaner had it nice and crisp. How anybody could think of riding this bike the way it was is beyond me but it worked out in my favor big time.

looks like a real clean bike, so how does it run?

It ran pretty poorly at first, the jetting was all jacked up. It's got a fresh top end on a 134cc build with plenty of compression and paperwork to back it up which is one reason I was not hesitent to pick it up. A V Force 3 block & reeds along with a JD Jetting kit and a little fine tuning have it running VERY well.

I thought the cr125 was the only bike JD didn't make a kit for? :whoa:

Nice bike Pat, how much?

Actually James suggested I used the CR250 kit. Yeah I was quite skeptical as well. But it seems to have worked quite well with a little fiddling suck as dropping the lean JD needle 1 spot and adjusting the air screw to 2.75-3.0 turns out.
