Throttle damper and other dampers on Honda CB450

 

I'm working on various parts of the bike, and there is still the
problem that the throttle doesn't go all the way to "slow" quickly
enough, in my opinion.  Although I have only tried one other throttle
and I wasn't paying attention at the time (yes, this is not a
sentence. Sorry.)  But it's still my opinion that it's ok until the
end, and that it should continue at the same speed all the way to the
minimum throttle position, but it doesn't.

Rather that remove the air cleaners and carburetors again, I
investigated the throttle damper.  I also took off the housing at that
point so as to more easily oil the cable (again).  I noticed that the
rubber handle itself didn't turn as easily as it might, but if I
pulled the handle only 3/8" off, it turned very easily.  I noted that
the handlebar didn't change diameter or surface or anything during
that 3/8" of even more, so that must mean that at the very end, it
fits a bit snugly in the right rubber handle, and I wondered if this
is intentional??????

Is the handle supposed to give a bit of resistance to turning when it
is all the way on, because of a slight friction fit deep in the handle
at the end of the handle bar?

I toook a thin, long screwdriver and tried to clean out grease gunk,
but didnt' find any.  Yet it seemed like there was something in there
on 10 or 20 degrees of the circumference, something that sprang back.
I'll admit I diddn't get a very good view.

My plan was to attach the handle 3/8" off the handle bar, but then I
broke the wire to the horn and had to fix that, and by that time I was
happy when I got the thing back together at all.  I can try again the
next warm day, but I thought maybe you guys would know.  !   ?

 Sounds like the grip was binding up with the throttle housing. I's
just pull it away an eith of an inch and see how it works. also
(careful now) you may find the throttle behaves differently once the
bike is running, being the carbs are partially vacuum activated.
