[2stroke_69]

Hey im getting a yz250 soon and wandering some info like some tips on what to do not to do my only experience with anything would be a polaris 500HO wich isnt very similar...
like what should i mix my gas at...what ratio im using this cheap motomaster stuff..
What kinda gas..normal premium..or av gas..
if i should mix in any extra addictive to the gas..like octane booster
Any other tips on anything since it'll be my first time driving a 2 stroke racer or any racer acxtually..

Thank, Alex

You can run it on pump gas, just get the premium(works much better). The ratio you mix at all depends on the oil. One oil everyone on here is obsessed about is amsoil dominator(370 banshee is a dealer) you can go on www.motosynthetics.com to get it. You should mix dominator at 50:1. Remember, use 2 stroke oil!!! Don't use any 4 stroke oil except in the tranny. I hope this helps! Good luck with it

first off get your fingers trained to grip hard its not going to be like a polaris 4 poke thats for sure.i never heard of your oil choice bfore i would be sure that its a thin high quality synthetic for high rpm motors first ,then i would mix it atleast 32-1 ratio on 93+ octane alot of people get confused on trhe whole octane booster thing, iuse it not because i think it makes more horsepower because it aids in starting and helps watery gas out if you do use it dont add a shit load one ounce to a tank is plenty,octane boosters use(ether) additives which is very different than high octane gasoline. oil is one of those often overlooked choices but its very important to a 2 stroke it could mean the difference of freshening your topend in half the time you would normally do it.get a manual on a yz as well and become familiar with your machine and dont trey anything stupid like a 40 foot double until you know how itll react under race conditions

Welcome to the site. =) good choice on a bike, I'm glad to see it doesn't have the F at then end of the model name. If your bike is all stock then 93 octane gas will be more than plenty, going out of your way to buy race gas would be a waste of your time and money.
