Topic: Throttle grip question

[krksquared]

The throttle grip on my 75 CB400F seems to need quite a few degrees of rotation to reach full throttle. I was at a bike shop yesterday and felt the throttle on new bikes (Ducati, Triumph, BMW, Aprilla, MV Agusta). They actually all felt the same. It seems like I have to really strain my wrist to reach full throttle on my CB. My bike is very original and I don't want to hack it up but is there a way to quicken the throttle?

you can get quick turn throttles,however if you yank these open too fast they gulp air and bog.

there a lot of threds abaut thange to better ratio..use newer parts..or make a bigger diameter adapter and glue on the old orginal one..the seargh just dont work

Have you adjusted all but a few degrees of play out of the pull cable?

Evinrude, I made one from black plastic PVC type stuff, heated it and formed it to the throttle tube. Worked like a charm.

A little goes a long way! Only needs to be like 3mm thick.
