No Ped Steve from Seattle, WA United States
So this kit appears to fit perfectly on the GPR50 and all arrived in good condition and the look of the cylinder/piston is all very clean etc. Going together well and for $200 it's hard to beat the included gaskets, o-rings, wrist pin and clips, exhaust studs and all. It's like a complete top end for the bike, nothing missing. I think the metal base spacer might be for Senda's or other Derbi motors, because when placed below the cylinder, it leaves no room for the stud threads up top. When I pulled the spacer and re-assembled with a single base gasket everything lined up perfectly. I'll edit this review after I get the bike on the road, but indications are that this is a high quality kit and just what you need if your GPR is shot or you are looking to bump up the power..
