I was running a 40 pj, #7 slide, G needle at thetop,165 mj. I have since shanged the mj to 170 and will try the LTR needle this weekend. I have been sent an '07 EC300 and should get it Friday. I have to assemble it and break it in soit is ready for Cycle Canada to do a multi bike test here in AB. I hope to take it out this weekend for a break in ride, though it is raining here and they are saying there will be 25cm of snow in the mtns tonight. I hope it melts fast. Should be fun.
