An air leak would be my first guess, especially if you overheated it. Did you do a compression check? Do that before anything, but I doubt it becasue of the high idle situation. Get it started and spray some carb cleaner or WD40 around the carb boots/reeds, but more importantly (at least in your case) spray the base of the cylinders. If you hit the leak it will instantly drop down the idle and you found you leak. Quote Link to comment Share on other sites More sharing options...
LeadBoots Posted June 7, 2006 Author Report Share Posted June 7, 2006 (edited) its got good compression 125 and 135. i didnt know a air leak could overheat a bike. i will try the spraying. thanks for the help Edited June 7, 2006 by LeadBoots Quote Link to comment Share on other sites More sharing options...
LeadBoots Posted June 12, 2006 Author Report Share Posted June 12, 2006 i tryed the spraying of the head and base gaskets and nothing i sprayed the carb boots and nothing. when its running i can pull the choke and it revs down to normal but when u let go it just revs up. and another thing when it running it just revs up higher and higher now until i kill it. i took the head off and the head gasket is fine. but the pistons were really black. the head didnt have any problems tho. its got 125 on the left and 135 on the right but u can turn it over with ur hand really easy. unless it is the base gasket i dunno. i havent checked it yet. i really need help.

fastcar01 Posted June 12, 2006 Report Share Posted June 12, 2006 I hate to say it but a crank seal would definatley do this, but unfortuanlly that is the harest thing to change out of all these. Did you verify that the slides were both returning down, when the throttle is let off. Make sure they both move together. Look at the joint on the cable where it splits from one to two, make sure the two cables coming out are seated in the Y real good, these can get twisted and not seated, causing a slide to not return down. If that checks out, you can try takeing the carbs apart and clean them real good. Still no luck I am going to go with a crank seal. I can not really think of anythign else it could be. Crank seals sound like a likely culprit, but check the other stuff first. Also did both piston look the same or was one leaner than the other (more carbon). You can test the crank seals by doing a leakdown test, I have neevr performed one myself, do a search and you find instructions. I belive you plug the exauhst ports and seal the intake, then rig up a air gun REGULATED DOWN TO A LOW PRESSURE, I belive around 10PSI, otherwise if your crank are not bad they will be after that.

BKOLFO4 Posted June 12, 2006 Report Share Posted June 12, 2006 Mine was acting similar to this, and the choke tube running between the carbs had come off of the right carb. Brian Quote Link to comment Share on other sites More sharing options...

LeadBoots Posted June 12, 2006 Author Report Share Posted June 12, 2006 (edited) the choke tube is in place and the slides do go down all the way. i am thinkin it is the crank seal to. Ok to get to the crank seal what would i have to do. i have never done this before and i dont wanna mess it up and yes both pistons were the same.

batoutofshell Posted June 12, 2006 Report Share Posted June 12, 2006 you gave to take the entire motor apart to change the crank seals Quote Link to comment Share on other sites More sharing options...
fastcar01 Posted June 12, 2006 Report Share Posted June 12, 2006 I agree that is what it sounds like. One more thing to check is to make sure you are getting plety of fuel to the carbs, pull off the fuel line and make sure it pours out. I have seen the peacocks go bad.

fastbanshee8 Posted June 12, 2006 Report Share Posted June 12, 2006 Before tearing into the motor, check your air mixture screws. They should be adjusted the same number of turns out, on each carb. They should be set somewhere between 1-2 turns out. Quote Link to comment Share on other sites More sharing options...
LeadBoots Posted June 13, 2006 Author Report Share Posted June 13, 2006 the petcock is working fine and the air screaws are set right. Quote Link to comment Share on other sites More sharing options...

creamsickle Posted June 14, 2006 Report Share Posted June 14, 2006 check the reeds. you may have a broken one. before you rip into the engine you should probably do a leak down test. its pretty easy you just need to get a kit or find somebody that has a kit. basically you plug the exhaust holes and the remove the carbs and plug the intake boots. then there is this hand pump, kinda looks like a blood pressure guage and well you pump it up to 6psi adn then watch to see if it goes down. 1psi per minute is acceptable. but definatly check the reeds. the same thing was happening with my sisters shee. you would start it and then it would just start climbing in the rpms. turns out one reed was demolished and the riht side wasnt firing at all just pushin out unspent air. and the right side was overreving. I am willing to bet, that will be your problem. Quote Link to comment Share on other sites More sharing options...
