Race fuel?

[njeffery]

Well some people I ride with only run race fuel in there two stokes some only will run 93 pump gas and some run half and half. My Tri-z is bored piped and jetted and runs great with 93 pump with GP7 and 32:1. What I want to know is people say the bike runs cooler on race gas does it? And if it does should I run it because cooler is better right?

Yes it should. Higher octane gas doesn't light as fast as lower octane gas. Hence you use high octane gas with a High compression piston, it doesn't pre-ignite.

In your case use the lowest octane gas you can that doesn't detonate, that will give you the most power with your engine.

Right on the money. The same applies for thumpers too.
