FMF Fatty Pipe...what do you jet with??

[jonnyweston]

Hey guys,

Finally got around to getting my FMF Fatty sorted for the bike (GASGAS EC125).

Just wondering before I fit it... is there anything I should know about jetting the wee bike??

Not sure what to do really? Whats recommended.

Last time I deristricted a TS125r (that I used for commutting to the city with supermoto wheels) I did nothing to the jetting....now that said the bike just died one day and I have not bothered to even check out whats happend to it to be honest.

Hopefuly there'll be a decent guy on here whos had experience with this bike, jetting, and alternative pipes!!

thanks in advance ! !

Did you get it running right with the stock pipe with what I suggested?

On our 125, the FMF required no changes and gave the bike more bottom/mid, good for a woods 125.

Hey there.... FMF FATTY...... GET ONE!!

Wow....what a difference that wee pipe makes.

The bike is absolutely perfect now as a woods bike.

The bottom to mid is much better now. I was out on sunday at a place nearby, which was very slippy with mud....none the less I thought I'd get stuck in with a few short hill climbs to test out where the powerband was....

...let me tell you, these wee pipes do exactly as they say on the tin...
(er I mean nickleplated 19guage steel)

Very pleased with it indeed, best £150 I ever spent on a bike!!

AS most of the enduros here in NOrthern and SOuthern ireland are short 15minute laps round hills, forests and fireroads, the wee bike now will serve me excellently.... particularly when the 4 strokers are getting stuck in peat bogs and other sticky stuff, my bik is light enough to literally "lift" out, and powerful enough to get me up the climbs and stuff that I did not think I could get up before!!!!

Cheers guys,
