I'm thinking if the dense cold air is making my scoot run lean (too much air), perhaps I could put a little tape over part of the intake hole. ? sounds good to me  If I had a manual choke I could close it a smidge, but that's not the case. And running lower octane fuel might help a little too ? The higher the octane the harder it is to burn, so if my scoot needs more fuel, low octane will burn faster & easier. The daytime temp here is 9-12c or 45 F Thoughts on this... |

I'd say either up-jet or go for the tried and true tape method. I can't imagine the fuel selection really matters, but perhaps a colder plug? That way you wouldn't have to re-jet nor tape. Just a thought. |

I'd recommend just shimming the needle. The cold weather affects it more on the low end so if you up size the jet you'll be richer on the top end and lose power. If its really cold (depending on where you live) you could shim it and up size the jet but i'd recommend trying just the shim first.

I feel you on the lower octane level, it makes sense. The higher the octane, the more it resists combustion. So, when it got a little colder in Wisconsin, I started using just regular gas. Don't switch to a "colder" plug, you want a "hotter" plug. The manual states exactly which ngk plug to get for colder conditions. Another huge thing with the ruckus, wait for it to warm up. I used to feel the exhaust pipe; if it's hot, ride it. Wait for er' to warm up a bit.

I can never remember which plug is better for lean engines and vice versa. Oh well...

With ALL motors, be kind, let em get some oil flowing through the system before you start making metal parts interact with each other. I had a mechanic tell me that it takes a full minute for the oil to be picked up from the pan and spread throughout the motor in my car. Ruckass |
