Just buttoned up new FMF woods pipe and am perplexed at outcome. Hard hitting mid throttle with wheelies, but lost the oem tractor lug at idle to quarter . The bike would lug at idle no problem prior to install, now it will stall if throttle not applied.

Purhaps I received a desert pipe by mistake. and was mis-tagged? How can I identify which pipe I have by appearence/measurements?

Did you adjust the jetting at all? if not then "Read the jetting guide"!

I asked the same question in my early years "how to tell the difference".

Here's the thread I started and what my woods pipe looks like, mounted on the bike:

Thanks for replies. Jetting was addressed before FMF was installed and run with stock pipie[45 pilot/155 main]. Needle left in 3rd position down from top

Air screw was also re-adjusted when FMF was insatalled. Thanks again

You may want to re-visit your jetting after the new pipe. You may be running a bit leaner than it was before.

. Perhaps a 42 pilot jet might be next. Removed the snorkel along time ago with fresh UNI. I miss my tractor pull.

According to posts, the very top of the woods pipe should have more distance/space from the very bottom of the plastic radiator guard, as opposed to the desert pipe having a tighter fit. I measured the gap at 1.5 inches with my "woods" pipe. Does that sound correct?

Thanks to all for input.

bet the jetting is off, follow the tutorial on how to jet properly, it''l tell you what circuit is off.

I feel the same way about mine. With the pipe off the bike, the upper mount has a stamp on it. If it says K-35, then you have the "woods" pipe. I think the "desert" is K-30.

FMF is notorious for mis-stamping those pipes. Just saying.

Yeah, pretty sure morning and lunchtime bong-hits are the norm at the factory

Surely not! that was a good reply though!

They are from "SoCal"

Seriously, I would not be surprised in the least.

Yes, what you have is the woods pipe. The rev pipe nearly touches the bottom of the radiator shroud.
As others have said, you may want to fiddle with the jetting - also Jeff Fredette makes a little torque ring that fits between the pipe and the cylinder - it only costs ten bucks or so and it works.

The stock pipes are the grunt kings, but not much else -
