This is all stock, it ran with these jets since new, nothing has changed, there's no reason I should have to change any parts inside the carbs for it to run in stock form. I'm just having some tuning issues.

Anybody? Come on guys, this is my last resort before I take it to the dealer.

So I have an '03 shee, bone stock, (got some toomey tr-6's in a box, kinda jumpstarted this whole project) with probably less than 100 hrs. on her. Always ran great, then I let it sit for about a year, (drained carbs) and the last few rides it acted a little funny. So I decided to tear down the carbs, clean everything, clean the air filter, fresh fuel, fresh plugs, etc. Now before I cleaned the carbs, my issues were as follows: 1. Low, unstable idle 2. Loading up when holding any throttle position above 1/4 in neutral. Bogging and stalling usually followed. 3. (excessively) erratic throttle under load at low to mid throttle. 4. Almost normal operation under load above 3/4 throttle. 5. Most recently, running on left cyl. only. After cleaning, both cylinders are running smoothly, idle is appropriately higher rpm and very stable (after some adjustments to idle screw and air-fuel screw). Sounds great, right? Almost.. Somehow my choke is out of sync, as the engine idles and revs normally (in neutral, not under load) only at 1/2 choke. No choke will destabilize idle and stall the bike. I've cleaned the carbs 2x, can't imagine there's any debris, so it must be a tuning issue, but after extensive fiddling with idle and air-fuel screws, I'm not making any progress. Any ideas? Keep in mind this is all pre-mod. Stock motor in all respects, stock pipes, etc. Thanks in advance for your help. (sorry to be so wordy) - Rob
