I believe my Honda RS125 GP bike made 44hp when GP Star sold it to me. THat was with a Motobum cylinder and A-kit piston I believe. Your numbers are very respectable for what you have done. Id ride/own it anyday... I had a RGV250 back in 95 when I started racing. It had a kit PGM, Jolly moto pipes and the rest mainly stock. Id say power in the low 60's. I thought a Honda RS125 would be no match til Chris Ulrich passed me at Tally and left me in the dust. Later I ended trading it for a Honda 125 and man those little things will fly. If anyone remembers running the OLD OLD tally before they changed the 90's etc I could run that track counter clockwise and hit the front straigh bump and power wheelie into T-1 on the 125!
So the bikes are still out here and still kicking around I made it out to Bushnell Motorsports park and had a complete blast. When braking hard coming off of the bridge, i am getting a little bit of rear wheel chatter. too stiff of a rear spring?
