Thumb throttle assembly

[Glenyboy]

Came across this, by the time you tidy up a stock honda one (as most are in bad condition). You may as well get one of these, they come in silver or black..

My dad had somethin similar on his 400 when he bought it. It was definatly a down grade from the stock housing. Definetly harder to push, an the extended lever was uncomfortable.

 

I also had one of them boysen shock grip deals or whatever they are that came with the throttle, and same story. Factory honda was better. IMO.

Thanks for the info Michael.

 

I have seen some new ones on there for sale but they are not genuine ones. They're reasonably priced but can imagine that they won't be as good.

So the damn throttle assembly does not fit my handlebars.  My bars are 7/8 and I guess the assembly is for 3/4 bars.  It won't sit all the way down on the bars.  Going to try and grind it down a little to get a better fit.  If that doesn't work, I'll be back in the market for a thumb throttle

Very strange. Maybe because it's for the 90??

My clamped on my 1-1/8 fat bar end and my flex ends. I thought all Atv/mx bars are 7/8 ends

I read you only use the 90's lever

Honda ones?

So I finally got my quad all put back together with the Honda 90 throttle housing & it's really stiff.  I lubed the cable and have double checked everything I know of - all seems to be in good order.    I know some guys cut a coil or two off of the springs in the carbs but I'd rather that be a last resort (and have extra springs on hand in case I fuck them up).  I read on a TRX forum where guys ditch the return spring in the housing altogether.  I may try that first.   Any suggestions?
