Gg ec300sm 07
I was looking for a roadlegal, twostroke supermotard for a time, and since ive had 3 GG before, I took a quick look at it.
Never seen a two stroke GG SM over 125ccm with newer-type of plastic, so searched my ass of for some pictures for it. Found 1 picture of the new plastic, EC300SM. Therefore, im uploading 2 pictures of my newly build 2006-2007 EC300. New plastics (2011) Sixdays Mexico, Messico front exhaust I believe, Vertex B piston with 0.20 ring gap, 1,1mm squish. 182# main jet, 42# pilot. Short standard silencer. 4pot front Brembo caliper with brembo master pump, 320 front disc and Morad rims. New front forks, marzocchi, all new wiring. Wave disc rear. Running 13-40 sprockets. Did tight the chain after pictures where taken.

That's frickin' awesome
The front rotor looks massive on that wheel, how's stopping power? Very cool man, you'll have to post up a ride report. Are you going to race it? Bet you get all kinds of crazy looks running a 2T SM |

those forks look like the sach's, in which case the compression dampining is at the bottom of the fork, the clickers up top are for the rebound..... |

Its not Sachs. Rebounds was the word I was looking for, thanks Compression is now also set, much better! Running 178/42 in the Keihin was a bit to small, now ive have a squirl sound, so guessing the bearings are shoot, this was also due to 0,15mm bottom gasket, engine poured in gearbox. Swapping to 192/42 (Main/pilot), just to get it thru inspection. Made out 17kw at around 4,5k (limit is 18kw.) due not willing to og on pipe. Porting both the cylinder and match-port barrel to house,new front pipe and jetting. Wondering about retard the 2k3 ignition for higher peak Power.
