I have cleaned and synced the carbs on my 94 750. When I start it up it doesnt start easily. When I start it it will slowly come to life. I can hear it trying to fire but it wont stay running until the rpms get high enough. I can blip the throttle and it helps alot to start it. Also, once at idle if I blip the throttle it will go up to 2500-3000 rpm and hang there. It wont idle back down until I barely move the idle adjustment screw. I am already at 3 turns out on the air/fuel screw. Should I go to 3.25? I have checked for vacuum leaks by spraying carb cleaner around all the possible leak points.

Still sounds like an air leak. Did you check the puke tube to make sure its plugged?Check the vac line from the # 4 to the petcock? Do you have a jet kit installed? Are you running a full exhaust? Are you using K & N filters or the stock? Give us a little more info about your setup since you have nothing listed in your garage info.If its not broke, Hit it with a bigger hammer and blame it on cheap imports

Did you make sure your diaphragms are in correctly? They should move up and down freely when u suck on the hole at the back of the carb that is at the top. If you open the throttle to start it, sounds like it might be really rich and flooding out. Mine will act like that when it floods out. I think 2.5 is a better setting.Must read for carb tuners......http://www.factorypro.com/tech/tech_...m_engines.html

If you want to take the boots off of the engine, you could check the o-rings on the engine side of them while you're in there. I'd recommend an impact driver for getting them off, though.Any and all statements by Loudnlow7484 are merely his own opinions, and not necessarily the opinion of Katriders.com.

Well the new screws didnt help. I will check out the o rings in the morning. If it was a vacuum leak would it return to normal idle the instant I barely turn the idle adjustment screw? I thought it would always idle high until I fix the vacuum leak.
When I first put it back together after all the work I did, it ran great, Idled correctly and smoothly. I took it for a test run and after 10 minutes of easy riding the rpms started to hang.

Run it for just a short while, and then check the exhaust pipes to see if one of them is much hotter than the others. If you've got a no-contact thermometer, then great. If not, just use a spray bottle and some water, and note how quick the water evaporates from the surface you spray it on.Any and all statements by Loudnlow7484 are merely his own opinions, and not necessarily the opinion of Katriders.com.
