Yes it let's it lug a little more, and gave it more bottom end grunt and the transition to when it gets on the pipe is smoother.
2011 Sixdays 300
- Thread starter biggstr6
- Start date
I have an 11 EC300 with a CCK needle, #3 clip pos, A/S 1 1/2 turns out, 38PJ and a 175 main. My bike rips, runs crisp, clean, has discoloured the pipe a bit, (has turned it a little yellow), but plug checks show almost a little rich. My buddies identical bike, same year, model, everything. Will not run very good at all with this jetting.Both bikes have 38mm ASII carbs, the only difference is I got rid of my handlebar choke and put a YZ250 one in. Any ideas? Are these things that different in jetting that they are going to need this specific of jetting?
iam the buddy
just checked the jetting again. 38 mm carb 2011 ec 300
178 main,40 pilot, a/s 1.5 turns cck needle #3 pos.
runs like its overfueled almost.
plug looks ok to slightly rich
my pike has the factory handle bar choke and ........PWK carb

one thing i'm really starting to notice-is one man's "jewel" in jetting is completely wrong for the next fella. case in point- i rode tlinemans bike yesterday on a short 5 minute loop and he followed on mine. his bike pulls and rips like a kx500,compared to mine being much slower to rev and mine hits the pipe much later in the rpm range. i personally prefer the way i've got mine setup ( all thought it's still a touch rich) as i find it suites my riding style much better than the point and shoot quick revving and hard hitting setup he has. he's a young hot masters level rider as i've been told, and i'm a 50's b level rider. i think there's a correlation here. so just a suggestion, maybe we should qualify or jetting spec's and preferences with a little "rider bio" when we post them. this may help folks to sort out what they are looking for as far as jetting.

Mine does the same thing. Only when initially spooling up the thottle. Not a bog type blubber, but more of a skipping/rev limiter type feel. No jetting changes corrected it. I tried the stock settings and settled on a JD jet kit for a YZ250.
In Sun mode it flat out rips.
Well said Cactusreid and a valid point. I'm having trouble making much of a splash in Masters though with guys like Prochnau laying waste to the rest of us....
Thanks again for the opportunity to exchange bikes. I do like your bar setup and will be looking to mimic what you've done there. Cheers

Yep. Mine does something similar, but it doesn't last as long as yours, as it cleans up quicker. It just on the bottom as I spool up the revs. The only thing I'm not happy with so far is the crappy footpegs. Mine broke on the second ride on a light tipover on a loamy hill.
GasGas, give me a new set of the stronger pegs like those that come on the cervates/nambo models.

These pegs will fit your bike (choose Gas Gas model, ignore the year, they fit the 2011 fine):

They sit slightly further forward than stock but otherwise they work great.

Randall, you might be on to something. Did you get those other mods done?
Thanks for the link Steve. I actually just picked up some moose hybrid 1/2 inch back offset pegs. Probably going to put a hammerhead shifter on with the offset to get the shifter extended a bit. Even with the 1/2 inch back it's still a tight fit, even with my size 8 Gaerne's. These gasser levers are a little short.

Figured my buddies bike out. There were 4 base gaskets installed in his bike from the factory. All the 0.5mm thickness. WTF? I get that GG try's to sell these bikes so that they'll run on crappy Euro fuel but 2mm worth of base gaskets? Took 3 out, re-installed and the bike runs like a top with the increased compression. Anyone else encounter this?

Mine came with 1.3mm of gaskets with 2.6mm of squish.
The gasket stack was perfect to set the exhaust port flush with top of piston at BDC. I didn't want to change port timing to lose top end so went with a high comp head which increased compression and reduced squish.
I may drop the 0.3mm gasket next top end to see how it effects the engine characteristics.
