Motor Revs

[bigvbanshee]

I had a problem with no spark unless I held the throttle in so I dissconnected the tors box and got spark. I tryed starting it several times but would not start so I sprayed some starting fluid in the carbs and got it started and running on gas after several attempts. The problem I am having is when I rev it up it does not come down it stays reved up unless I turn the off switch just to the point where it will cut out then it will idle normally. Carbs are clean. I looked in the carb throat and made sure the throttle was not sticking and it was working like it should. Any help would be greatly appreciated. I t is 40 degrees in Md so I dont Know if that could be affecting it.

Everything is stock on the bike. How do I adjust the carbs?

Since your bike is revving up on it's own, it's running REALLY lean. Don't try to ride it until you get this worked out. The very first thing I would look at is the fuel strainer screen in the tank. It's easy to get at if you drain the tank. You can then flip it over and remove the fuel petcock valve from the tank. You will see the screen on the end of the valve, probably full of crud. I cut mine off an put an inline filter between the tank and carbs, works better than the strainer and much easier to get to. Sometimes a float will stick in one of the carbs, and a few sharp raps on the side of the carb with a srewdriver handle or similar medium-weight tool will break them loose. If neither attempt fixes the problem, you will need to take the carbs apart for cleaning.

disconnect the fuel line and check for good fuel flow. if the flow is bad check the screens in the tank as stated above. if you have good flow clean the jets and passages in the carbs. also check for cracks in the intake boots,choke tube between carbs, loose cylinder bolts, loose intake screws. goodluck

I am checking the carbs and boots for air leaks as eveyone has suggested. I also just checked the compression. I tested each cylinder and cranked them each 4 times. The left cylinder got up to 130 and the right got up to 125. Everything is stock on this bike so are these acceptable readings. Thanks for the input.
