Thanks to the good people on Betarider I think I have good jetting for the moment.
Bike is strong, no sputter at low revs and flies in the high rpm's
Jetting is 38 pilot , 168 main and the NEDW needle #3 airscrew 1 turn out.
Elevation is 30 m and temp range 5C -15 C . Mileage has improved I can ride 110 km before hitting reserve ( trail riding)
I upped my oil ratio to 3% with synthetic 2t oil. I also changed from 98 octane fuel to 95 octane fuel (10% ethanol) and strangely the bike runs better and is giving me way less spooge so all is good.
One strange observation I had today is:
When I came on nice long straight dirtroad I pinned the throattle, bike reved till the moon . At the end off the dirt I turned arround as I was going to take another run I noticed a lot off smoke coming out the exhaust, light blue color. The smoke cleared after riding for some time at a moderate pace. Did took the dirt road again with same results ...
What is going on here ? Is that old oil in the exhaust being burned out ? Higher engine temp ? Rich condition at WOT ?
