Dream Revving high!

Post by deadbeathero » Sun Aug 12, 2012 10:40 pm

Hey everyone,

I had been having issues with the fuel system on my 69 Dream. After taking the carb apart a few times and changing out the gas, I went ahead and completely cleaned the fuel tank. I kept finding residue in my filter so I figured flushing it out was the best option and it worked!

I can get it started now on the first crank BUT it is revving super high! Maybe its a vac problem?

I tried testing for that but the bike is jumping around so much when its on that its hard to not want to turn it off. I checked the throttle cable and it is loose and should not be the issue.

Has anyone else experienced this issue? Or is my bike possessed by the spirit of Evil Knievel?!

Have you checked that the throttle slide is seating properly? It is a common problem to put it in backwards. Cutaway should be to the air filter side....

Yes. That was the first thing I thought too. I took the carb off and watched it as it set. I also checked the cable at the lock screw and loosened it all the way. Anything else come to mind?

Is it possible that the slide moves but the needle is stuck? I tried pulling the needle up with some needle nose pliers and felt it move. When I went to start it it wouldn't start, but gas started pouring from the overflow.

your throttle twist grip assembly is hanging up. pull it apart and the fix will be obvious. deburr the slide and the handlebar groove. grease with silicone lube. oil the *** out of the cable. the cable seems loose on the carb end but is hanging up at the other end.
