Hello to all.
I just built my first motorized bike. Built on a mid 90s Ross diamondback 186, steel lugged cruiser, 26" wheels. with a HS 142F 4 stroke. I love the bike and am now looking for more speed. I drilled the fuel mixture plug out, drilled the main jet to a # 72, opened up the air box, and drilled several large holes in the stock exhaust box baffle. It runs great with lots of low end torque. I'm thinking next will be a better carb and I will build custom exhaust. After that I will install a shift kit to be able to use the 7 speed cassette. I am retired now but worked a Harley Davidson mechanic for 35 years. I'm have as much fun with this little bike as I did with my first H.D. back in the 60s. Amazing, LOL. This is a great forum with tons of knowledge and great people, I look forward to picking brains and sharing my project.
