does anybody know if the R-series is out for the 250/300ex yet. any body have it for a 400ex, did it make a difference(performance,Noise)

 

What on earth are you talking about?? The only R series in Honda 4 wheelers were made from 86 to 89(TRX250R) and the 3 wheelers(ATC250R) were made in 86 and prior(sorry ATC guys, I don't know all the years for the ATC models).

 

wv250r i think he is talkin about the white bros. r series pipe.

 

you're dumb im talkin about white brothers r-series b4 you make a smart remark next time know what your talking about

 

I don't think that White Bros. has started making the R-Series pipe for the 300EX/250X yet. But I can't wait for them to make it because that's exactly what will be on my 300. I saw the pipe on a 400EX and the fit and finish of the pipe itself is so amazing!!! It makes you look twice at how nice it is. It stands out on any modified 400EX or Warrior you see it on. But until they do bring it out, I'll have to stick with the stocker until I find another one that I like.

 

I put a r-series on my 400ex and it bolted right up and looks good. It is very loud but not a problem, I got all the dogs barking in the neighborhood. I also installed a K&N and a 152 main jet. I'm hearing guys putting on 155, 165 and even 170 mains. I'm having good luck with my 152 maybe I'll try jetting up to see what happens.
