That is exactly when it happens, at 6200ft after a steep long climb. From about 5500 ft to 6200ft in third then down to second gear. This is the only time it boils over. Tight trails at 6200ft does not make it overheat. I went richer on the main jet, from 165 to 170. We'll see.

Claude,

Climbing requires the most power, generating the most heat. Extended climbs are where you see peak temps.

Evans NPGR coolant was an excellent solution for me to prevent this corner case overheating.

What jetting are you running in your Gasser for this 6200' ASL climb?

I just rode all over from 6000 to 10000 ft in Idaho.

I have only boiled the coolant in my 2000 GasGas 300 3 times and so the '05 has yet to boil over. I climbed many steeps switch-back hills in Idaho in August on the '05 and I was sure that it would boil over, but it I experienced no problems.

My jetting was:

40 pilot
#8 slide
LTR needle in position 2
168 main

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.
