Need help

[matt1]

Here is what I have, My bike is hard to start cold but once it's a little warm it fires first kick every time. My problem is that after roughly 45 minutes of riding the left cylinder stops firing at idle. This happens every time I ride it for 45 minutes or longer. It also sometimes but not always revs up(only right cylinder firing ) about 1000 rpms during this time. This is what I have done so far. new float needles(gas was coming out of the over flow tubes) checked float hieght cleaned carbs, resynced carbs(using the sight windows) sprayed carb cleaner around carbs looking for air leak, new plugs, fresh gas, checked comp (108left 110 right) With engine warm and throttle open. I have verified choke tube is in, float bowls are on the correct carbs and so on. I also tried switching switching plug wires and plugs with no luck. The torres thing is still on the carb but all wires are disconnected and the torres control box is removed from the bike. I have a Mr Gasket temp gauge in the radiator cap and it never gets above 190. I get a little water dribbling out the over flow hose every time I ride.

I did a leak down test and found bad air leaks at the reeds. fixed that and it held perfect, no pressure drop after 10 min. Just test rode it and it still does it. It did the idle up when you grab the clutch every once and a while and won't hit on left at idle. I also noticed it doesn't want to pick up the cylinder with clutch in. What the hell I need help, could it be reeds. They looked fine from what i could tell. could it be a crank seal only leaking when hot. Also could it be bad port work causing this crap. This thing has been a pain in my butt since I got it.

Switch plug wires one cyl to other. If it follows wire its the cap. Check picup coil, outside of flywheel, lower right. gap should be 18 thousands. Check that both nubs on flywheel for pickup are CLEAN. If that doesnt cure it check all wires carefully, check grounds, tightness/cleanleness of conecters. Cdi, coil bolts tight? Check stator wires/clean poles, inside of flywheel. Hope this helps.

Well i finally figured out my problem. Some how the pin that holds the slide from spining in the carb got filed down or backed out enough to let the slide rotate. I was able to drive it out far enough to get it to hold slide and keep it from rotating. Has this ever happened to anyone before or do you think the prior owner did this?

i've heard about that before. i think it happens from someone trying to force the slide in when it's not perfectly lined up, then it's just loose after that tomove around.
