Gnarley pipe
« on: March 03, 2009, 07:28:08 AM »
Will it fit under my IMS 3.6 gallon tank?

Also I understand its  a better bottom-mid range power pipe than stock? Does top end go away?

With stock reeds, will it make any difference?

Neither are stock, and both are great desert bikes.

SO is the top end still good? Heres a pic of mine. Notice the bash plate. Think that pipe will fit with it?

Nope, not without some mods.  The lower portion is fatter and has a different curve. Excellent pipe but it takes quite a bit of "rush" off the top end.  I liked it since I typically ride fastest using midrange power and short-shifting. Not a pipe for screaming through the desert. For MX it would be awesome. Cam.

Well, I dont MX. I ride alot of single track here, and the bottom end is still good enough for me with stock pipe. And the FMF ISDE can.

I also do lots of desert stuff and want to keep what top end I have. So that pipe sounds like it isnt for me.\

Ideas for more power without losing topend, and maintaing the bottom end?

I have a Gnarly under my IMS big tank and it fits perfectly. The Gnarly moves the power to a lower RPM point,and I dont think it revs quite as high, but this makes the bike nicer to drive on tight trails and deep mud.
 My kicker does however bump the pipe a little unless it is completly folded in.
 If pipes were cheaper, I would love to have a selection to play with.

Gnarley Pipe with a KX250 tank. I like it more bottom to mid range power.

  I have the stocker and the GNARLY- i am in the process of de-bugging my recently purchased 2000 KX500- ive replaced the air-filter with a new UNI unit,checked the jet sizes :168 + 58 and cleaned the carb out and will re do the float level- after researching I noticed that i should have re-bent the float tang -ill do it tommorow..anyway,back to the pipe thing..i havent ran the bike optimumly until the float is done but as far as the pipe goes [GNARLY] I dont dig it too much -i probably will put the stocker on until i can get the other pipe on [pro-circuit]or??- I want full rev out and i ride more flat out style than plunking slowly so i need the MX setup than woods... BTW, I gave up on a street kit for my KX5, I got me an ol DR650 that is great for around town, work ,etc so when i get this ol SUZY up to snuff [jet kit,bars etc..]then the KX500 will be restored to her former glory.... :lol:

Plus, was that measured at the wheel?
