I just bought a 2006 CRF 50 for my 4 year old. He likes to grab a handful of throttle and run in to stuff.

I heard that these bikes have a throttle limiter. Is that true? If so, where is it and how do I adjust it?

Parts number 13 and 14 are the throttle limiter and jam nut, located right on the throttle side handlebar mount. If your bike is missing those parts, they are a 5x32mm pan head screw and 5mm nut.

Good to know about the bolt & nut size. I think mine is missing them. Is a 2000 the same?

Yes, they are the same part numbers on the microfiche diagram for the 2000 model.

I "BELIEVE" so but not 100% sure


If they don't, another option, is to use like a rubber hose, a fuel hose, or any hose you got laying around.. And cut it short, say 1/2" or something, and put it on the throttle cable, INSIDE the carb.. That way, the slide can only open partially.
That's a free throttle stop that will work on any bike. Would be nice if you were to say get a older child into riding on a bigger bike.. Couldn't hurt to put a 1/2 throttle stop on a kid tryin to ride a cr125 :ride:

The 70 does NOT have the throttle stop, as shown [COLOR="Navy"]HERE[/COLOR]. You can't put a 50 throttle assembly on the 70 bars because the 50 bars are 3/4" and the 70 bars are 7/8".

I also have my sons CRF 50 backed down. Until he gets a better feel for it. then I will open it all the way back up.

good to know :busted:

but for anyone that needs a throttle stop on ANY bike, keep in mind the fuel hose INSIDE the carb to limit the throttle, works great, and only takes 10-30 minutes to install and limit your throttle on ANY carbed bike :banana:
