Does anyone on here know anything about them?
I know they are the originator of the STIC for PWK carbs.
I was on their website cruising around and saw some impressive numbers out of their yz125 motors (40+hp). I’ve been tossing around the idea to have some performance mods done to mine.

Derek did my motor on my RM250. It was a rocket! I highly recommend talking with him. Great dude.

Harris Performance- Very knowledgeable, helpful and enthusiastic - especially about two strokes.

However, the STIC process was originated (invented) by George Boswell, although Harris is a STIC dealer and has done a good amount of testing with it on various bikes, and is frequently in contact with George.
Harris is very familiar with the design and process.

Was STIC a part of the original Boswell Engineering carb that was rumored to make Rich Taylors '96 privateer CR blow the doors off of MC's bike to the first turn?

He's a personal friend of mine. He does top shelf work. He is very knowledgeable on motors and suspension systems.
