So Good and Tasty September 10, 2018

A little quicker than stock. Machining looks really good. Came with the piston and rings installed in the cylinder.

Solid Cylinder!! October 29, 2015
taco eater : blackumi from Moreno Valley, CA United States  
Very very solid for a stockish cylinder!

The rings were even in the correct spot already!

Transfers could be a little larger, they are only a little larger than stock.

But very solid, fits with no issues

*update* I dropped my rating to 4 stars, only because the piston shown in the picture is not the one that is included.

not perfect fit March 18, 2012
taco eater : Aaron Fowler from Richmond, VA United States  
apparently my 40T has a "slow" bottom end. spent 1.5 hours filing +.5mm from the outer diameter of the bottom 9mm of the cylinder skirt. then it fit great!

blasted the (completely worn out and rusty) stock Blunderbus ball style exhaust right off and kept ripping.

Good quality kit April 18, 2011
taco eater : George from Boston, MA  
Super nice quality kit - clean molding and good finish inside cylinder, the only thing I can think of doing is enlarging the intake to match the Malossi shorty, and rounding off the ports (rings click just a tiny bit).  Ports look like a ported fast cylinder, but I should get a rubbing to confirm.  I broke a piston ring when fooling around with mine, and was able to replace it with a stock ring.

Overall, a well built stock-plus cylinder.  Excited to put it on my bike.
