I need an internal throttle!

<< < (2/2)

andy120t:
I found this diagram online - it's a Honda C90 throttle assembly and shows the slots required in the handlebar. These bars look as if they are square too. I'm going to try & source one to see if I can make it work, but probably be more academic than for real use.

I've previously mocked up one from a piece of copper pipe (in place of a bar) but as it's rather soft & not that easy to work with it ended up being very sticky & not that usable. It gave me some insight into cutting slots in round bar though.

I also found a thread that says these twistgrips only open about 3/4 of the way....so there might be a loss of top-end....or high tick-over.

Dave M:
I had one on my CB125S and found that you needed 2 handfuls of throttle to get it fully open. It was quite stiff too.

The throttle on my Indian was on the left-hand side, with the clutch being operated by foot and a hand gear lever next to the petrol tank; very strange beast to ride.

Wasn't this called a 'suicide clutch' ?

florence:
Not sure, but certainly difficult to get used to.  Probably brilliant on those long straight US highways but awkward off-road.
