Rt1 to RT2 changes #1
I had both as new bikes and now am rebuilding both. The mechanical changes between models seem to be:
Three bolt chain guard became two bolt
Reed valve induction
Different battery
Mechanical advance on timing

What have I missed? My faltering memory says that the RT2 was a much smoother bike to ride, and easier to start. The RT1 fouled plugs every 300 miles but maybe that was the two stroke oil we had at the time. The second plug was always gummed up and no help.

RT1 did not have a compression release for starting, the later RT1B and beyond had a manual Decomression system

Mine would have been a mix n match for sure as had the advance flywheel plus the original cylinder decomp. Piston port RT1 that is. No wonder i could sit on the seat & start it if i wanted to lol. They realy should have carried that flywheel right though to RT3 but suppose too many moving parts to worry about not that they were realy a problem except for wear around the piece that engaged in the cam & no doubt gave slightly fluctuating timing but mine still worked good. Had a look in my farm shed last week & not much left. I know i've sold a few bikes but then i forget [head injury] & think hell where are they--been about a year since looking lol.
