Crf230MX

okay to start does the crf250 have the same body size as the crf 450? and also can you put on dual exhaust to a different year 250 other than an 06'?

tigmaster

yes, the body is the same as the crf450 is you are talking about the crf250r and the crf450r. i dont know about the trail bikes. i dont know if u can get dual exhaust on different years. try finding a dual exhaust pipe and see what years it fits.

i am most likely going to sell my 230 after summer, and after i have earned a few bucks, and then sell it, and buy a crf250r, which i really want dual exhaust. its just one of those things thats a must have.

Its cool to hear your going to buy a crf250, Gratz!

The thing about the duel exhausts, tho, is the crf250's seem to run better with a single exhaust. Its a little odd, but it seems that the single exhaust seems to get on the power sooner.

Anyhow, I want to say that the 2006 CRF250 subframe is different, from 04-05. The only difference is the mounting bracket for the duel exhaust. You should be able to fit the duel exhaust on another year, but you might need to make a new bracket.

Have fun on the crf250!

on another forum i saw bikes where guys had fitted dual exhausts to bikes other than crfs, one guy even made a xr a twin piper! Be warned however, on the other forum there were rumors of the 250's eating valves alive!

tigmaster

it just depends, the crf r series using titanium valves which are crap. the xr's use stainless which is super durable. also the crf r series bikes have a more agressive valve angle.

In particular it was the new twin pipe crf's that are eating their valves, probably just first year bugs that need to be ironed out yet.

titanium valves have this magical coating on them to prevent oxidation. if you do not practice good valve maintainence, the valve or the seat can be damaged due to a valve always be open a bit. also if u like smashing yur bike off of the rev limiter consistenly, u will go through titanium valves real quick. i didnt want to deal with all the stupid problems that titanium presents just to gain a little hp so i went with a full valve set from kibble white. dont worry i still have lots of titanium parts, like my retainers are now titanium.

wow your knowledge of engines is far beyond mine, though im not too shabby if i do say so myself lol

tigmaster

i have been workin on engines for a long long time, well seeing as im not that old "long" may not mean that much. its just what i do and anthing involving car work is super easy also. i have never taken my car to a mechanic. never taken my bike anywhere either and am afraid because most mechanics dont really know that much, plus i just never had the money to pay someone else to do what i could do.
