A while back I bought this '71 CL70. Did a bit of a "rustoration" on it and had the original engine built out to 117cc. That was a fiasco....it blew up three times and I pushed the bike to the back of the garage.
My original plan was to do a pit bike swap. I'm getting the itch to do something with it again. I'm leaning towards a Piranha 140cc, a.k.a. the YX 140 engine.
I read about upgraded carbs, bigger exhaust needed, charging system, etc. Then there's the whole converting to 12V and CDI thing. Splice into the existing harness or just swap in a complete new harness? And what about an oil cooler?
I'd like to be able to cruise easily at 45-ish MPH and occasionally hit 50-60 for short stretches when needed. I've already installed a 46T sprocket on the rear and, if I remember correctly, I was using a 17T up front.
Can any of you walk me through doing a swap that would be kick only but still run lights for the street? The CL70 is titled and is street legal. I'd like to be able to eventually go out and beat up on a Grom. Or at least give them a run for their money!
