    Comments On Mar 12, 2012:R&d makes a great product! Used the power pump 2 on my yfz450, made a huge difference in low rpm performance. if your planning to ride in tight trails, this is a must have for the yamaha yfz450!

    Bolt on POWER !! For my KTM

    Comments On Jan 17, 2012:WOW, my KTM 250 XCF is much more responsive with the R&D Power Pump. Big Big difference particularly right off the bottom, no more lag/bog. Bike is much more fun to ride. If you have a KTM thumper this is a must have add-on!

    eliminate ktm 4stroke bog

    Comments On Aug 29, 2011:combine accelerator pump with jd jetting kit and completely eliminate that ktm bog. easy to install, takes longer to get carbeurator out, than it is to install.

    Why don't these come stock???

    Comments On Oct 25, 2010:This should come stock on any fourstroke just like a fuel mixture screw, idle adjuster, and the power pump! Absolute piece of art! Perfect fitment, easily reached for adjustment. And tons of adjustment, tune the hit out for slippery hard packed tracks or tune for totally aggressive response for loamy tracks or tracks with lots of jumps. I highly recommend this product to any modern fourstroke owner pre-fuel injection!
