I am looking for more info on the RX1 Eastern Cycle Performance Kit including spark plugs, air filters, prefilters, 165 mains, Holtzman Carb springs? Heard it gave about 16 hp in the midrange? What about at peak? What does this kit cost? Anyone using it in deep powder, if so hows it working for u? I am thinking of getting rid of the stock airbox. Anyone with first hand experiences please fill me in. Do any of you have a dyno chart with this mod over stock? Thanks, Justin
 

I run that setup and they make a huge difference over the stock airbox. There are dyno sheets over at ty4stroke.com. Deffinitely a big wake up call, makes them just run better all around, if I remember correctly they're about $240.
 
Sounds good

Sounds like a good inexpensive mod for a nearly 15 hp in midrange and 5-7 peak. I heard they sound pretty sweet as well.
