Carpenter Race Engines

The Suzuki Hayabusa has been the unquestioned leader in big-bore sportbikes since it was introduced in 1999. And since that time we have not stopped making them go faster! We have been in constant development and are now on our 5th generation Hayabusa Port.

Over the years we've built dozens of 'Busa's which feature modifications from mild to wild. We can build you a street legal, and totally rideable and reliable, 210+ horsepower Hayabusa or anything beyond.

We stock pistons, complete bore kits, clutch modification kits, valve springs, and an entire array of products specifically for the fastest production motorcycle ever built. It's time to make yours faster... give us a call!

We now offer a phased approach to let you ease into your buildup and spread the cost around. Put $2200 into your bike and get the full cylinder head package less cams. Add the cams later (including adjustable sprockets re-tuning and mapping) for an additional $1400 for the 210+ package.

210+ HP 3300 Hayabusa Package

We've taken our 200 horsepower Street Busa package and tweaked it for another
5% horsepower gain. Like the 200 hp package, the 210 hp package utilizes
the renowned Carpenter Racing 5-axis CNC head porting.

The 210+ hp Busa package features:

This package can record over 213 rear-wheel horsepower at 113 ft lbs of torque
with stock pistons and stock valves!

Using the first offering of this package Steve Jester went 8.83 @ 159.90 mph on motor
with DOT rubber and 60" wheelbase in 2004!

Complete with Clutch Fix, Air Box Mod and Power Scoops installed

230-240 HP 4400 Hayabusa Packages

We just can't leave it alone! The porting and cams brought the Busa to new levels
of performance. Now what will a piston kit bring? We had to find out!

Two flavors are available: 1397cc for everyday riding and the 1430cc for track use
and the occasional blow-your-friends-away street jaunt.
When they ask if you are spraying look at them like they are crazy!

Both Packages include everything in the 210 package plus:

The 1397cc Package produces 230+ Horsepower
The 1430cc Package produces 240+ Horsepower

We have been building stroker Busa motors for years but never before
have we been so excited about it.

We combined our 240 kit with a billet stoker crank with titanium rods for a
dependable 1630 cc displacement. Our palms were sweaty as we rolled it over to the dyno.
The results were stunning!

As of January 1, 2010, 17 of these engines have been built and raced without one bearing failure.

After some development on the fuel curve we came up with over 280 horsepower.
By our calculations, 280 horsepower on a chassis dyno with a street tire equates to
320 hp at the crank - Now we are talking Pro Stock Power!
