feti68 Posted July 1, 2004 Report Share Posted July 1, 2004 I cleaned out my carbs as suggested by Dextreme. My pilot jet in the left carb seemed to be clogged so I blew out whatever was in there with compressed air. I put the carbs back in. But I'm getting high-revving even when I'm not pressing the throttle lever. The carbs are synched and the idle air screws are 1 1/2 turns out on both. Over the past few days I've installed a new throttle cable, clutch cable and clutch lever. I don't know if anything in the throttle cable housing at the top could have anything to do with the over revving. I noticed that the TORS does have some connections inside, which may be part of the problem. I'd also like to do an air leak check and am wondering what I can spray on the engine that won't erode any of the gaskets. I only have WD40 handy, but I don't think that's too good of an idea. Another thing I find odd is that if I turn the throttle cable in up near the lever, that's when it starts to rev high. But when I turn it out it won't rev up at all unless I press the lever. But the difference is not gradual as you might expect. It's a tiny twist and it goes from not idling to over-revving. Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted July 1, 2004 Report Share Posted July 1, 2004 Hmmmm..Thinking...Do your slides in the carbs bottom out? Perhaps they don't. Disconnect the cable from the thumb throttle and try it out. Also, a little eather sprayed around the carbs will let you know if you've got an airleak. But before that, Did you take apart the TORS housings? maybe somthing is not adjusted right? Did you screw the caps on all the way? Try putting the choke on...maybe your running too lean.

racer Posted July 1, 2004 Report Share Posted July 1, 2004 well whenever you figure it out tell me, cause mine does the same thing and its really pissin me off. it seems like its idling on the right and then when the left starts to hit it revvs sky high. but i dont have tors Quote Link to comment Share on other sites More sharing options...

But before that, Did you take apart the TORS housings? maybe somthing is not adjusted right? Did you screw the caps on all the way? Try putting the choke on...maybe your running too lean. The slides are not down completely. There is a minute gap maybe 4mm that I can see. Also, I did have one of the TORS housings apart when replacing the throttle cable originally because I wasn't sure which side I had to open. Also, when I put the choke on the revving does go down which does make me think it's getting too much air to begin with. But the question is where? Can I spray WD40 around the carbs to find out? The screws on the caps of the tors are all the way in and the left is slightly out more in order to sync the carbs. The throttle cable near the lever is screwed 50% in and if I push it in any more it will attempt to rev high. It just doesn't make sense why such a minute turn in the throttle cable near the throttle lever would make it go from non-idling to over-revving Quote Link to comment Share on other sites More sharing options...
feti68 Posted July 1, 2004 Author Report Share Posted July 1, 2004 (edited) I think I found the problem after I inspected the cylinders for cracks. Somehow my right cylinder where the reeds connect there's a minute 1/2 inch crack and it's split out so you can nearly see inside. I put some JB weld on it temporarily to see if that helps. Once it cures I'll try it out. Does anybody happen to know if the JB weld will hold once the engine gets hot?

feti68 Posted July 2, 2004 Author Report Share Posted July 2, 2004 I took the top-end off and replaced the bottom gaskets and the o-rings because I saw some oil around the exhaust ports. It's still revving like crazy. I didn't see any oil around the head gasket so I didn't take it off. Could there still be a leak in the head gasket that I can't see?
