Good value for additional power and response. Stock DR-650 with DG V2 slip on. I used the 155 main jet and pilot jet that was provided with this kit. Only used one of the needle shims, drilled an extra hole in the slide with 3/32 bit and drilled a hole in the top of the airbox 1-5/8. Used 2-1/4 turns on the fuel screw. I cut 1/8 inch off the spring. Runs slightly lean but smooth at low rpm, and pulls harder than stock. Very happy with the purchase and would buy again. Thanks guys!

Anyone that takes carbs apart has experienced the problems of getting the phillips head screws out of the body and floatbowl . They usually get boogered up . For what this kit cost they should have included 2 or 4 allen head bolts for the float bowl and cap on top . Instead of a new needle like other kits supply they send shims . A new bowl gasket would be nice as Well. I just think that for what you get it's overpriced.

The kit worked out well for my initial problem of flat spotting on sudden acceleration but although not as bad I still have a bit of a surging problem under low throttle.
