well my ex is almost sold and i am getting a 250r i was wondering what u guys thought about the ct 250 powervalve motor but i got a few questions 1, is it worth 1400? 2 what are the horse power numbers 3 what do u think top speed would be and 4 do u think it is reliable i really need to know because im purchaseing motroe stuff asap also im gonna get the ct midgerqange pipe ans silencer plus v force reeds and a carb kit do u think this is good well thanxx for all the help

 

if im not mistaken, the power valve does not give you more power, all teh powervalve does is give you a smoother powerband. now i think on the ctpowervalve tehy use a pro-x head which allows for more coolant flow, this intern could make yoour engine run cooler and you may gain some power that way. now you can have your head ported and gain power taht way as well

 

A powervalve gives you more low-end power.

 

The PV does not give much more power but it does give MUCH smoother power, 'no hit'.
I say it is worth it! Check out CT's 350 PowerValve.

 

If you're just getting a 250R, I'd look into having your stock cylinder ported. The powervalve motors are ok, but you get much more bang for your buck with a simple OEM cylinder port (and done right, very big hp for a 250)

 

i think i decided on the ct racing 310 power package because it comes with the cylinder kit the pipe v force reeds and the carb so it seems like a good deal then im gonna get srong arm +2 arms and a lonestar axel and some other goodies like rims and tires and maybe a new swing arm does anyone know if the stocks 250r swingarm is good??? also maybe a new carrier or something any recomendations would be great thanxx

 

Stock 250R swingarms are useless. For MX the aluminum 88/89 swingarms break and the longer 86/87 steel swingarms are too long.

You need to get a better aftermarket carrier, the stock unit will fail in no time with a longer axle.
My LSR twin row carrier has help up great.
