i notice others here speaking of engine numbers like the tomos a55. it got me thinking maybe the nc50 had a number to it that other honda peds shared. so far i don't see anything so my guess is it is only built for the nc50 but shares similar characterisics with a few of the others.
thought it might help in finding performance parts, like a pipe and carbuerator (if i'll need one), along with that link for the cylinder.
maybe this is a bad idea?
i do have it running pretty damn well. there is only a gogola googala putt repeat sound when riding downhill @ about 25mph WOT, rides at about 20 uphill, then around 22/23 on flat.
