[QUOTE="bultaco4ever, post: 1384942, member: 111771"] I've never heard of changing premix ratios to compensate for temperature and air density changes. I change jets to compensate for that. Oil only lubricates. Fuel actually helps 'cool' the piston when it gets in the combustion chamber. So, correct 'jetting' is more important than the premix ratio. I heard advice that says on a long downhill, where you're riding the brakes and keeping the throttle closed, that it is a good idea to pull the clutch in and blip the throttle to drawing in some needed 'cooling' fuel make contact with the piston crown. On a cold winter day when more oxygen molecules fill each space of cubic area in the combustion chamber you need more fuel to maintain the 18: 1 airl/fuel mixture. (I think it's 18:1) Adding more oil won't add more gas to the fuel mixture. I don't think changing the ratio will ever replace correct jetting. [/QUOTE]
