for an 02 220. which pipe is better REV or Gnarly?
I do mosty woods riding and want more juice for steeper uphills
Having no previous experience with any pipe on any bike :) I made the decision based on information I got from the hop-up section of the KDX only website...
From what I gathered from the info there, the Gnarly Woods pipe would add to the 220R low to mid range, but after 6000 RPM it would run flat very much like the stock pipe.
WIth the Desert (rev) pipe on a 220R, it would add power across the entire range (not as much as the woods pipe for low end, but alot in the midrange and far more at the upper revs)
Since I am new to dirtbikes, and the bike had more than enough torque for my beginner bones, I thought adding across the board might be a good move...
After adding the desert pipe and TC2 Q silencer to my 04 220R it seems to have a little more torque down low (noticeable), it definitely winds out better at high rpm (very noticeable) and the midrange hit is astoundingly more intense! (would have to be dead not to notice)
In fact, the midrange hit was so much more powerful that it nearly jerked my grip of the grips it was so unexpected the very first time I experienced it after the installation.
I think I might have gotten very lucky with the overall carbeuration as my bike runs very smoothly, idles like a dream, and has no hesitation off idle (after a slight airscrew adjustment) I think it was running very rich in stock form, and now with the new pipe and silencer, runs leaner (but still a little on the rich side)
As a side note, I was expecting my bike to be much louder, but such is not the case... I would say if it is louder, it is only because the "ring-dingding" 2-stroke sound is a little more noticeable, but I actually LIKE that sound :) so decible wise I would say its exactly the same as stock from what I can hear.
Good Luck!
