Buell Blast Motor Upgrades.

As some of you all know I have a blast and have been reading about the 515 bolt on kit and the 600 big bore kit. I also just found out theres a 44 Magnum Big Bore kit

Thought I would post some info for anyone else with a blast looking for information. Pretty good read.

NRHS and Revolution Performance sell their own 515 and 600 kit, but no word on this 44 magnum kit.

I will Add to this when ever I get more information about upgrade kits for the blast.

This is from NRHSPerformance.com


Don’t let your mild mannered Buell Blast fool you. Arm-jerking torque and acceleration lies just under the surface with the addition of an NRHS engine kit. If you want to turn your Blast into an EXCITING motorcycle to ride, you’ve come to the right place! Our engine kits turn this docile little motorcycle into a screamer.

It’s amazing how much fun a Blast can be with twice the factory horsepower or more.

515 Bolt On


The Buell Blast is a terrific little bike, but nobody has ever accused it of being a powerhouse. Until now anyway! Properly installed and tuned, the NRHS bolt-on big bore kit transforms the Blast into a FAST little bike, and it does it without the expense or hassle of boring the cases!

A Blast running an NRHS 515 kit even set a record at Bonneville, running in the 650cc class! These kits now feature a premium quality iron lined aluminum cylinder, NRHS forged piston with tool steel wrist pin, Total Seal rings, and Cometic EST gaskets. We believe these to be the best parts available for your Blast.

Take your Blast to the next level with a bolt-on big-bore kit from NRHS!

600 CC Big Bore Kit


Whether you want to go dirt track racing or Bonneville racing or just embarrass guys on much bigger bikes, the NRHS 600cc big bore kit is for you! This is the biggest bore size you can safely fit into the stock Buell Blast cases. Each kit includes a premium quality Axtell aluminum cylinder, NRHS Hurricane forged piston with tool steel wrist pin, Total Seal rings, and Cometic EST gaskets.

We believe these to be the best parts available for your Blast. Take your Blast to the next level with a big-bore kit from NRHS! Available as a top end kit or a complete package.

Note: this kit requires boring of the cases for installation.

Can You Handle a 44 Magnum?

Brian Nallin is hot and heavy into developing a new high performance big bore kit for the Blast P3. The kit will provide a whopping 720 cc displacement, an increase of 228 cc’s over the stock 492 cc thumper. Be advised however, that with the 44 Magnum high performance big bore kit fitted, a mild mannered Buell Blast engine will no longer be a thumper.

Rather, the P3 powerplant will be transformed into an earth pounding, fire breathing, pile driver!

Brian Nallin (formerly) of Nallin Racing (now at Revolution Performance) has dubbed the new mongo big bore the 44 Magnum after the fact that it displaces 44 cubic inches.

Bore and stroke are squarely balanced at 3-13/16 each. As such, the 44 Magnum will be capable of reliably revving to 7,500 rpm while laying down well over 70 hp worth of thrust to any surface willing to accept it.

But what about power band you ask? It will be corn fed, grade A BEEFY. It has to be; Nallin Racing will be taking the engine to the track, fielding a 44 Magnum powered dirt tracker in the Pace Open Class series.

You can bet the engine will be reliable as well as a VERY strong performer.

Folks, this is comparable in power to the stock pre-Thunderstorm twins and well over twice the crank rated 34 BHP of the stock thumper! How much does a P3 weigh again? Dry weight you say is 360 pounds? Are you grinning yet?

Salivating maybe?

Imagine the look on an unsuspecting X1 pilot’s face as you leave him looking at your tailight blasting away from a stop. The kit is sure to be economical too! Just think of the wear you’ll save on your front tire.

The engine is still in the midst of rigorous testing/development, but come mid-July Nallin Racing plans to have kits available for public consumption. And yes, for those wondering, the big bore stroker kit will require a new crank; thus splitting the cases will be necessary. Nallin Racing will be more than happy to perform that service for you if it is more than you are comfortable tackling yourself.

I’m reeeeeeealllllll tempted to start saving my nickels and dimes, and tens and twenties for a road racer track bike fitted with a 44 Magnum engine. TOO COOL.

Not ready for a 44 Magnum? Nallin racing currently has a 515 cc high performance kit for the Blast that bolts right on, simple as you please, and you’re pushing 50 RWHP. They also offer a 590 cc kit, but that requires boring of the cases to accomodate the 3-13/16 bore.

Check out http://www.nallinracing.com for contact information and other offerings from Brian Nallin and the folks at Revolution Performance.

Stay tuned for updates and photographs.


PS: No price yet. How much is it worth?


A little more blast information avtually gives you a bit more tech just seems like a lot to do for the 600cc kit.
