Specializing in Classic Kawasaki Motorcycles

If you have a KZ, J Model or GPz Kawasaki or GS series Suzuki that you're interested in building horsepower with, we can most definitely help you succeed with that project. The classic Japanese in line 4 cylinder motors are our passion.

That doesn't mean we only focus on the classic bikes though. We're here to handle the porting work for the late model sport bikes and cruisers as well. Our porting formulas and methods apply to all motorcycle performance projects. You get the same quality port work, no matter what your choice of ride may be.

With over 25 years of high performance Japanese motorcycle experience under our belt, we've developed and refined a strategy for making horsepower. It's founded in science and earned through effort, testing and building engines.

Engine Rebuilds

KZ, J and GS classic inline 4 cylinder engines. If you have a project bike and you're interested in having a shop rebuild the motor, contact us.

There's another part of the equation when it comes to "quick bikes" THE RIDER! The guy pictured in the photo is Marty Powers. Trust me....He knows how to setup a KZ to ET if you're building a KZ based drag bike, we can put you in touch with Marty.

Useful technical Information is found on our KZDATA page. Had enough Internet Forum arguments. Grab the accurate information on that page. On occasion I visit KZR and Cycle Madness forums to see what's guys are building and thow in my 2 cents when I see bad data being given. How can anyone hope to succeed with misinformation?
