Recommended Posts

ok my stock cylinders are trashed, so I'm going with a 421 cheetah cub. I plan on ordering it this weekend but am lost on what dome size I should get with it. i was told if i set it up for race fuel i could get more life out of the top end. is that true? we have 110 avalible at the pump but what size domes should i get for 110. otherwise we have 92 at the pump. what do u guys recommend i do?

No, order it from someone who can give you all the tech info you will need. I think BP is a sponsor here, but I feel like ordering it from one of the guys that build them for a living is the better way to go. Guys like Jeff at Fast or Cam at Redline are able to give you solid set up advise, jetting info, etc.

 

As for the race fuel, find new people to get info. Who ever told you it makes motors live longer is a looney toon living off one misconception after another. Race fuel if put in a motor that doesn't require it will not burn properly and will actually make less power on a motor not built to run race fuel since it doesn't "explode" the way it is meant to. Slower bang means less violent piston motion.

 

Race gas is intended for a motor with more compression and/or timing which normal pump gas would combust before the piston reaches the proper position for combustion due to pressure and heat. When that happens folks call it detonation,pre ignition, or other related terms. Basically it is a way of saying it is lighting way to early. When that happens you can expect damage if it is prolonged. So race gas has a higher octane to resist combustion till physically lit by the spark plug. So when race gas is used in a motor designed to burn it, it combusts with a bit more of a violent explosion creating more piston energy. In turn you get a motor that is more fun, but it is harder on a motor. Parts see more abuse then a pump gas motor would.

The only way I can see race gas being easier on an engine is if the engine was setup for race gas.

For $110 more, you get Cam's porting, assurance, properly cut domes, and knowledgeable customer support.

that's what i was kinda thinking but was told the lead and oil in race fuel is good for a engine. i just checked out redline I'm going to go with them, it looks like lots of menbers here have good things to say about them. so what cc should i go with for 92 octane i also have a adjustable stator plate for timing?

Just tell Cam that you want to run pump gas.  That's all that's involved.  Let him make the decisions.  It took me 2 years to decide who to let build my engine and Cam is who I decided on. 

so u recommend pump gas over race fuel? i like he 110 idea because i have it easily avalible and the people i ride with also run it.
