Hey guys.........I was wondering some specs on the 450r carb. First off, what brand/make is the carb? Next, what is the stock jetting(both main and pilot)? How big of a carb is it(mm)?? Has there been any problems with it? How is it for response, response over rough terrian, etc? Thanks

Brad

 

it is a kehin(spelling?) i believe it is a 41mm stock main jet is 118, not sure about the pilot i have the hrc kit and a pipe on mine and the pilot didnt need to be changed, main is now a 190. i love the carb and it has super response throughout the revs.

 

Keihin 42mm butterfly, very smooth carb, very consistant throttle response.
I sold mine to a guy who installed it on his Predator (Mikuni 42BSR cv carb) and he said it was night and day. Is that what you are thinking?

 

A lot of racers keep the stock carb. Should tell you something.........

Throtle response is excellent, and it doesn't flood or bog in the rough.

 

Yes I am thinking of putting it on my pred.......I am pretty sure it is better than mine now, and not as good as the ones I could get(fcr, lectron) but I can't really afford them either. I think I can get a 450r carb at about 165 bucks, and a throttle cable of some kind too........


KGB...........The guy I know said the same thing, he is from Texas though.........

 

Thats my old carb. Ernie, huh?
Good luck, there is a guy selling one at trx450R.org
New they are only $165 at servicehonda.com
Used they should be under $100.00

 

yep thats him.........he is very helpful and very smart too..........


Thanks for the info about the site, I'll check it out.........

 

The carb that is on the crf-450 dirt bike has a much better and race ready carb. It will cost around 350 from service honda, its a 40mm keihin carb.

 

Hello all:
I know how a cv carb works, but I thought some of you 450 guys or gals can help me understand what is a butterfly carb. thanks
