That is an impossible question to answer. Each bike has it's own characteristics, different compression rations, different exhaust and different porting. It also depends where you are in the United States. The dyno is the only way to achieve perfect jetting. Making a balance between maximum horsepower and maximum efficiency, while holding maximum reliablility.

How much horsepower will a Big Bore add?

That varies from bike to bike. With dyno readings we've achieved more horsepower, more torque and reliability through porting and polishing and dyno tuning.

What will I gain by Porting and Polishing?

The top 5 manufacturers (Yamaha, Honda, Suzuki, Kawasaki and Polaris) mass produce heads and cylinders to help control cost leaving a significant amount of horsepower to be gained. Porting and Polishing will improve your throttle response, hole shot, horsepower and torque. This is one of the highest gains in a motor build.

Should I change my Ignition System to gain more power?

We would love to sell you the parts, but 99% of the time, on the dyno to achieve maximum power and the best curve, stock is the best setting. If the bike stops building power at 7000 rpm, why set rev limiter at 10,000 rpm?

Do I need to run race fuel?

Only if the bike is built with high enough compression and needs the cooling factor and detonation characteristics of race fuel. We have spent hours with some of the top national racers on the dyno and have proven many times that on a production motor 91 octane builds more power and curves.

Are there different Dynamometers?

Most of the dyno that exist are horsepower and torque dynos. The only dyno capable of properly tuning a bike is a dyno that uses a brake system to hold your bike in specific rpm ranges. The industry leading dyno is a DYNO JET Eddy Current Dynamometer.
