The ultimate cylinder kit for motocross, cross country, TT, or just blowing your friends away in the backyard! We have been testing this cylinder for quite some time before releasing it for sale on Project Blaster's website.
 
This cylinder comes with everything to just bolt on and go! For the Fire-Breather Cylinders, you will need to send your head in to have it worked for the cylinder (the head work is included in the price). Stud Kits are optional for $20 extra.
 
In his first race using the Fire-Breather Cylinder, PB's Joe Margaria won the 2005 John Penton GNCC in 2-Stroke A class on a Blaster! That's never been done before on a Blaster in the history of the series! After taking over two straight hours of abuse, the cylinder didn't drop in compression or show any signs of wear. In 2006, Joe won the GNCC Sport Class National Championship, having no problems with the engine the entire season.
