Race Gas 4 YSR

[ysrfreak87]

I was wondering if any of you out there have any suggestions for what type of race gas to run in a stock YSR. My bike has boyzee dual stage reeds, Nology wire, Japaneese stock pipe, and a #92 jet with calamari dyno jet needle. I want to be competative next year and make the bike run a great as possible. Also what should my premix be with the gas?

no race gas needed for a YSR. Just run 91 oct (or equiv) pump gas and premix (Yamalube R-2 or your favorite brand) @32:1

down in so cal, unocal 76 sells racing gas at some of it's stations for about 6 dollars a gallon. i think it's 105 octane or thereabouts. it works...

As long as you arent getting any detonation(pinging), it wont make any difference, and can actually slow you down, higher octane burns slower.
Unless you mill the head or go with a higher compression piston, it's just throwing money away.

91 octain pump gas is good. I don't think it'll make any difference, anyway.
