400 ex thumb throttle?

[gregw338]

Will the 400ex thumb throttle fit the 250r

It will fit, I had one on mine, but it wouldn't open my 41mm carb all the way though.

same thing is going on with my bro's 250r. He has a 400ex thumb and his 38mm a/s doesnt open up all the way

It fits, and it works, but it doesn't work properly.

Without going into all the details, it works okay, but it only allows your carb to open about 90%, it doesn't give you a true full Wide Open.


Edit: Oh, look. While I was messing around with the sprinklers in my yard, a couple people beat me to it.

If someone needs a 250R throttle by any chance, I one with a billet K&K cover that I need to get rid of.
