    Has anyone got any tricks for "sticky" throttle tubes on the 610? I've tried re-routing the cables and greasing the heck out of the tube/cam assembly and this sucker still wants to hang up a bit. I'm running Pro Taper bars w/ Moose guards and as far as I can tell there are no clearance issues. It does not appear to be a cable problem and the drag seems to be in the cam/tube area.

    cheers,

    I'm sure you've checked this but if the tube is to far inward, the butt end of the grip will drag on the end of the handle bar. Might move the throttle assy out a bit and give that a try. Also...don't crash on that side...left side only!:lol:

    Do you have wrap around hand guards? If so the throttle might be dragging/binding on the mounting bolt in the end of the bar.

    What you need to do is get a hold of George at UpTite.

    He has an ultra-deluxe throttle tube w/bearing. I resisted George’s temptations on this thing for a long time. A tight, no-slop, throttle tube didn’t make much since to me because off-road you are bounding around anyway. Well it does. Seems that the slop in the throttle tube yanks the cable around when the throttle tube rocks. That ends up bumping the carb slid on every bump. Eliminating the slop gets rid of that and smoothes out the throttle pull amazing well.

    I've found with barkbusters that over time dirt will enter the end of the bar and cause friction issues between the bar and the inside of the throttle tube. If you drop it in muddy conditions it amplifies the problem.

    Before your jump to any conclusions take it apart and clean it.

    I had this same problem and I didn't believe it at first but the nut on the end of the thing that flays out inside the handlebar tube can actually slightly and temporarily distort the shape of the handlebar if you do it too tight or if you drop it on that side, despite them being tough and cause the throttle tube to stick.

    I had the same type of problem on my one TE610--eventually I just replaced the throttle cable --end of problem. The cable had 38,000km on and by hand pulled in and out easily . The moment I connected it to the throttle tube it dragged. After stripping it a gazillion times I determined that the cable inner had cut a groove into the plastic bend at the turn by throttle. This made it to drag and return slowly under tension
