Rejeting 350 Banshee Overbored to 65mm

well, the thing about premix ratios, and what the manual says, is that it is based on low end oils, and stock jetting. the factos are 1: a higher grade oil is made to run in smaller amounts and has higher viscosity and protection, with more burn-off resistance, and 2: the larger the jets, the more premix, ergo more oil, than the 200 mains almost 2x as much, which also means viscosity of changing it now could make the difference of as much as 2 jet sizes. i would do the 32:1, find a good oil, and pick some more mains up

 

 

That makes since alright. I'll try and get my hands on some more mains asap. Didn't get a chance to go play with it yesterday, got called into work so hopefully I'll give it another try during the week. Thanks again

Yes 32:1 with any oil will be good, if you can get some good oil 40:1 is good too.

Did you say the spacer plate that came with your crank is under you head? It should be between your case and cylinders, maybe thats your problem.
