Hanging rpms fixed

Post by Billyz »



Just got this 77’ running . Had the carbs rebuilt by pistol pete. I thought it was running pretty good , but noticed sometimes the rpms would hang around 3000 . Seemed worse after i got it hot. I read somewhere about tightening up the carb boots. And low and behold that was it. Rpms drop right down , idles at a lower rpm . Its a lot snappier now too. It pulls harder.
So thanks for the tip.

I'm minimally technical but not sure what you mean by "tightening up the carb boots". Could you explain a little more or add a picture. My '77 idles a little higher than I like (about 1000-1200). I have lubed the linkage as best I can, but I sometimes find that when I reach down and push it down, it will drop the idle by ~200. (Snappier would be good, too.)

There's two throttle cables to the handgrip connected in a loop. A "Pull" cable, and a "Push" cable. If they're adjusted too snugly it can cause the throttle to bind a little bit. There's adjustment points both at the stainless elbows at the handgrip and at the other end where the cables connect to the carburetor linkage.

If you back off one of those adjusters just a little this will add a slight amount of free-play to the throttle at the hand grip, you might find the idle returns easily to where it belongs without pushing the linkage.

The carb boots he was referring to are the rubber connections to the carburetors on each of the four intake elbows. There's a clamp holding the boot to the carburetor.

Thanks for the explanation. The bike is in covered storage in the rear of my garage (I'm in MI) but I now know what you are talking about and will check throttle linkage and boots in the spring.

One of the throttle cables has an adjustment under / along side of the airfilter container. You have to remove the aircleaner assembly to get to it.
