xslice Posted January 2, 2014 Report Posted January 2, 2014 Stock carbs on 2002. When purchased(used) the left side idle adjust would not thread in all the way. Re-tapped carb body and now idle screw won't hold position. Should I try to re-tap or can a heli-coil be inserted? If so what size heli-coil? Any other ideas/suggestions would be appreciated. BTW - If anyone has a set of factory carbs-26mm that they would like to part with please message me. Quote
SAVAGE420 Posted January 2, 2014 Report Posted January 2, 2014 Use a little Teflon tape. Or use a nut under the screw like in my signature link of the tors idle screw install thread. Check it out if you want. 1 Quote
joey83 Posted January 2, 2014 Report Posted January 2, 2014 Ditto. ^^^ A thin nut might work best. After the idle is set just run it in and lock it down. Is there a spring on yours? Tors deleted? 1 Quote
xslice Posted January 2, 2014 Author Report Posted January 2, 2014 Tors is deleted. No spring. When I tighten down the lock nut the screw pops out a bit like the threads aren't holding. Thought about Teflon but wasn't sure how it would react with gasoline. Quote
uman1030 Posted January 2, 2014 Report Posted January 2, 2014 Some one made the hole slightly too large when drilling/tapping for idle screws not saying reg old white teflon tape wont work but supposedly gasoline dissolves it id use the yellow that is for natural gas, hydraulics and other petrol-based applications.. 1 Quote
xslice Posted January 2, 2014 Author Report Posted January 2, 2014 Just resolved prob. The nut on the original screw was stripped at the head of the screw and wouldn't adjust as it kept trying to crossthread. When I removed the TORS and hit them with a sledge, I installed a new idle adjust screw/nut combo. Also, re-tapped the hole as the original was excessively tight. Well, the new screw wouldn't hold position as it kept popping out of the internal threads. The old screw fit nice and snug. Hacked sawed off the nut on the old and installed the nut that came with the new and all is well. I also noticed when I tried to put the new nut on the old screw it was very difficult. Could it be that I got a screw with out of spec threads? Or that the screw that came with the bike was an oddball? Both looked the same to the naked eye but obviously they aren't. Thanks for all the suggestions. Quote
thomas h. Posted January 2, 2014 Report Posted January 2, 2014 Could look for a new carb as well. Or JB the hole and drill tap again. Or helicoil if you can get a kit that size. Quote
dave5.0 Posted January 2, 2014 Report Posted January 2, 2014 I've got a carb I might part with here shortly. Quote
xslice Posted January 2, 2014 Author Report Posted January 2, 2014 ^^^^ Let me know. Bought this for my son. We have really enjoyed working on it together - quality time! Quote

xslice Posted January 2, 2014 Author Report Posted January 2, 2014 Left carb.Thanks. I will gladly pay you. Quote
dave5.0 Posted January 2, 2014 Report Posted January 2, 2014 That might be an issue. Think I need that one for the choke. Quote
xslice Posted January 2, 2014 Author Report Posted January 2, 2014 Well I also could use the right one as the elbow from the fuel line to the bowl keeps coming out. Quote
dave5.0 Posted January 2, 2014 Report Posted January 2, 2014 Haha ok. I've got two sets. One with torrs eliminators and one stock. Somebody already interested in the torrs set but I've got to go through my stuff and see what I need and can get rid of. Quote
