Poor gas mileage 2013 christini 300 with gasgas ec300

[lneil06]

I bought a 2013 Christini 300 all wheel drive that has a gasgas ec300 motor in it. Main jet is 155, idle is 42 and leak jet.

The bike runs really well, smoky on first startup but that's about it, a bit of oil out of the exhaust after riding for an hour or so.

I mostly ride at 1/4 throttle in the power switch on the lower setting. Only hit 1/2 throttle occasionally. Never hitting full throttle.

Power is linear.

Gas mileage 9 to 10 mpg ! Not good and don't see gas on the ground when I stop. Yes i did say 9 to 10 mpg.

HELP! Going to changet min jet tp 170 due to altitude, riding at zero to 2000 feet.

Need some help!

Thanks
Lenny
