FMF Gnarly
 

Anyone run a LTR jetting kit and a FMF Gnarly on their bike? I have a 2002 EC250. I was woundering if you might know what size pilot, and main i should run. I have a 45, and 185 in right now in the 3rd needle position.

THANKS!!!

I have never changed jets with a new pipe. Did you get the old Gnarly or the new sst/doma Gnarly? I run a 42/178 in the 2nd slot in my 02 300 if that helps. Lots of jetting info in the database.

45 pilot and 185 main sounds extremely rich unless it's winter riding at sea level. Around the trail area I'm usually around 40-42 pilot, 170, 172 or 175 main depending on where I'm riding (river valleys, 175; high alpine I run a 170).

How does your bike run? What's the plug look like?

What does the LTR come with stock? I was running the LTR stock in the middle needle position. When running the LTR set-up i was a little lean on top. It was rich on the bottom thoe. Might have to pull out and check the jets.

The plug was really white brown almost white at the tip. The bike felt fine befor i tore it down but mabe a little lean on top.

What's your elevation? I didn't think PG was that low. For fall riding I'll probably go with a 175 main and probably a 42 pilot, needle in the 3rd clip.

PG is about 1800-2400 at most. Right now its about 3 to 13 degres or so. I am going to take it apart to night and see what is in it. Going to clean it and put all the other stuff together as well. Thanks for the Help.

If the bike is running clean (no blubbering and pulls clean right up to WFO) I wouldn't mess with the jetting. But I'm guessing it's going to be rich. There is a jetting database on here, might be worth a look.

Mounted up the pipe (some bending and what not) and looked at the jetting. It has right now a 185, 45 and #3 postion. Just befor i rebuilt it i had a 182 in it with a 42. So i will ride today or tommorow and see if and where it is rich. I asume be rich then lean on a new top end. I still have a bunch of different jets. Thanks again.

185 main should be pretty rich. My 300s won't pull onto the pipe clean higher than a 178 main. I hate a blubbery bike.

Well tommorow i will test and see. I too think a 185 is too rich. I am going to try a playing with them. I have a 185 to 175 anyways.
