I installed a billet thumb throttle (extended) Bought it off someone on the forum, came with the spacer which I am sure goes between thethumb throttle and housing. Tightened the bolt.

If I just push on the throttle normally, everything seems fine, but if I grab the bottom of the thumb throttle, I can move it back and forth with my hand.

Does not seem right that it would move??
Do I add washers??
Any ideas?

 

I was thinking the one I had was a machine fit. are you sure the housing is not hogged out?

 

You havent mounted it correctly. The square shaped pin must match the throttle arm. You currently dont have the squares lined up.

 

Thanks ODP, I will try to correct tonight.

 

Hi cpaul,

I also purchased one of those extended levers.
I don't know if I installed it correctly but the actuation worked great but the positioning of the lever was all wrong.
It killed my wrist as I could not grip the bar correctly. I ended up putting the stock one back on.
Maybe I will try it again I hear you have to move the whole actuating lever over to get the right location ?
Any one else know if this is correct ?

 

That is interesting, I have heard nothing about the actuating lever, left mine the same.
I worked on this thing for almost an hour last night. Must have re-installed it 15 times! Still has some play if you grab billet thumb piece and rock it back and forth. May be wollered out a bit?
Don't notice it when you are just "on the throttle" will try it and keep the OEM one just in case.

Thanks for everyone's help!
