Somedumbguy Posted April 7, 2013 Report Share Posted April 7, 2013 I have searched have not found anything about my problem! I just rebuilt my shee to .030 over and now she won't idle. It has stock bottom end. Wiseco Pistons. Stock carbs with 280 main jets and 25 needle jets. Air screw 1.5 turns out. Needle on the fourth clip. Carbs are synced and floats are in correct position! This was my setup for stock at 6500ft. not sure if I need bigger needle or main jets? I tried to raise my float's so it would idle and that don't work! when I give it gas it's real throaty, as soon as I let off throttle it dies! Has new Plugs ,Oil , Gas "40-1" Ratio , and New Clutch.. Bike was running great when I tore it down just figured after 2.5 years it was time.. When I tore it down I found my pistons moved in cylinders so that's why I bored them over. Nothing else was wrong with it. Quote Link to comment Share on other sites More sharing options...
Starwriter Posted April 7, 2013 Report Share Posted April 7, 2013 I'll bet you swapped the slides. If they're in the wrong sides, the slide cutaway ends up toward the motor. The cutaway should be towards the air filter. You did a leakdown test after assembly, right? Quote Link to comment Share on other sites More sharing options...
noonansar Posted April 7, 2013 Report Share Posted April 7, 2013 Did you clean the carbs before you reinstalled them? Do you have tors or have they been eliminated? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 7, 2013 Report Share Posted April 7, 2013 also if you have stock carbs, have you made sure that the choke tube between the carbs was back in place? Quote Link to comment Share on other sites More sharing options...
Somedumbguy Posted April 7, 2013 Author Report Share Posted April 7, 2013 No I have not done a leak down test. This is my first rebuild and have never needed one. I will make or buy on today. I made sure both carbs were cleaned before I reinstalled them. The slides are in correct carbs cause the little silver notches come into the windows and choke tube is installed. It does not seem to be running lean as it still smokes a little when I give it throttle and no popping. Just wont idle for me! Next step is the leak down test. After that maybe a bigger pilot jet?

sheerider11 Posted April 7, 2013 Report Share Posted April 7, 2013 Are the pistons in backwards? Quote Link to comment Share on other sites More sharing options...
Somedumbguy Posted April 7, 2013 Author Report Share Posted April 7, 2013 Piston arrows are forward.They are real tight. No movement what's so ever but when I turned the flywheel it was Not hard to turn. Quote Link to comment Share on other sites More sharing options...
Somedumbguy Posted April 7, 2013 Author Report Share Posted April 7, 2013 Went and rode a little bit. It still won't idle after its warmed up. I only was giving it 1/4 to half throttle. Runs great. Blowing blue smoke like normal. As soon as I stop giving it gas it dies and I have to pull choke to start it again when warm. Fuel issue maybe needle jet?

joey83 Posted April 7, 2013 Report Share Posted April 7, 2013 A top end rebuild shouldnt need to be rejetted. Do a leak down test asap. I personally wouldnt ride it until you did. Float level will not change idle, just how much fuel is sitting in bowls ready for engine to pull in. Did you replace intake gaskets or reuse any gaskets? Did you replace any seals in bottom end while engine was out or just top end rebuild? Check for cracks in intake boots where cross over tube pops in.

noonansar Posted April 7, 2013 Report Share Posted April 7, 2013 Have you tried to idle it up with the idle screws or tried adjusting the air screw? Quote Link to comment Share on other sites More sharing options...
Somedumbguy Posted April 7, 2013 Author Report Share Posted April 7, 2013 I still have the boxes on top of carbs but no tors box. I tried to mess with the screws on top of carbs nothing really changes. The air screw is about 2 turns out nothing really seems to change. I did just top end with all new gaskets. Gonna do a leak down test. Just have to make one first. Will check boots also. Quote Link to comment Share on other sites More sharing options...
noonansar Posted April 7, 2013 Report Share Posted April 7, 2013 Have you had the pilot jets out and cleaned them? They can clog very easy Quote Link to comment Share on other sites More sharing options...
