Bike starts and immediately revs to 5000rpm

After I had my carbs cleaned and rebuilt, and after I reassembled the entire air/fuel intake assembly onto my bike, it starts, with no choke needed, and revs up to 5000rpm all by itself. I have checked the idle screw, it is turned out and not in contact with the throttle, and the float bowl levels w...

Re: where to find replacment throttle butterfly?

As in another butterfly by itself? I have looked and haven't seen a way to order them individually or in a set of four. Do you know how to get one?

where to find replacment throttle butterfly?

Upon reassembly of my carbs off of an 81 CB650c I accidentally jammed the throttle butterfly for the no. 2 carb in the body of the carb. The retrieval process left the aluminum throttle butterfly quite mangled, although the interior of the carb looks fine an unscarred. I haven't been able to isolate...

Re: Lack of Power in higher gears

Re: Lack of Power in higher gears

I'm sure the carbs could use one. Do I have to worry about resetting/re-synching anything after I have removed and cleaned them? The manual I have is not very descriptive. I will check on the voltage later today, thanks for the suggestion!

Lack of Power in higher gears

Hello everyone, its great to get on the forum and I am excited to get more involved in the CB650 community! I bought a 1981 CB650C back in December and since that time have experienced a noticeable lack of power going into 3rd, 4rth, and 5th gear under acceleration. At first I thought there was a pr...
