Rcx, 2nd test run in LA

I modified the pipe on the Rcx and the bike feels better even though I couldn’t read the max rpm because of a wrong setting on the tachometer. I’m getting close now and we’ll start doing some tuning on the carb (too rich) and the transmission (variator + spring tension and gearing). Overall the bike feels solid and good enough to be competitive on the first race. I don’t want to go t00 crazy with the pipe or compression ratio to keep it more reliable and have a bike running at every race.

The bike reached 57 mph at the end of the straight with Drew’s GPS. I still need to tune the gearing to get a solid 60mph which should be enough on those small go kart tracks.

    Why do you want to build a pug? any problems with the moby?
    I actually like mobys better for the race track being faster and pug for street bikes with more after market parts.
