Coincidentaly, I had already ordered a replacement 50 cc motor, and that came yesterday. Thought I might again try a diamond frame roadbike- an Atala- build- in fact I'd like to go 40 or 33 ccs but not finding anytjing that looks not too difficult to mount, and finally decided, as the last time several years back that the chain stays simply don't have enough clearance without using tensioner, which really then defeats the whole "small motor/ extra light" build I'm thinking about- Got a little plastic gas tank for ten bucks that would save a lot of weight too, figured I could hang under the top tube and attach to seat tube at rear-
Its a tall frame- 24"
wish they'd make something that had a side fill to hang closer to the top tube, or that would fit in a cruiser gap- I think we'll see more alternative plastic tanks soon
but scrapping that whole idea and bolting new motor in place of this old 50- it probably has 3000 miles on it anyway- at least 2000-
have newer jug and piston extras right now- so may pick up a bottom end in the future to build up another spare- kinda expensive BGF just raised the price of theirs
the 66 is running good- but too much motor, doesn't want to slow down and idle and harder to start again- I ride shutting off the motor continually and then kicking back on on the other side of a stop
I really find the 50 better suits my needs and fast enough with alloy 39 sprocket
this bike weighs about 47 pounds- I'd like to see something around 40- basically a vintage raodbike with a smaller motor is probably the only way to get that light- alloy on everything possible
if I can get the small gear off, I may try replacing that, but don't think I want to take the clutch apart to get new bearings and probably not worth it considering the use it's seen-
The bike is now just a chain and final tightening away- but rain predicted next million days here, so not fretting over it.
playn my new fiddle instead.
