How ya goin, I'm Phil from Adelaide Australia, below's a couple of pic's of my raty motorized pushy.
It all started around chrissy time when I ran out of strikes on my drivers licence and copped a 6 month suspension, 40 km round trip to work and bugger all puplic transport, was time to get fit, lol.
I cycled for a few months, 240km a week (work saturday mornings to) built up some killer legs, lol, but every morning I would be past by this 60 year old bloke on a mountain bike that sounded like a badly running lawn mower.
Bit of searching on the net got me the chinese 66cc engine and I picked up a alloy framed mountain bike with araya rims, shimano gears, cranks etc, with flat tyres, broken cables no seat for 40 bucks at crime convertors.
I pulled the motor down before I fitted it, had an idea it would be fairly average engineering wise as the cost was so low, took it down to a mates engine recon shop, cleaned up the ports faced the head, top of the barrel and the cases and made up some new studs.
Set it up in the frame with 2 3/8 exhaust clamp up front and modified the rear mount to get it lower in the frame, that also got rid of the long studs for the mounting, chucked on a 8mm top gun lead and NGK plug, at first was a bit disapointed, ok I had to bed the rings but it struggled and sounded off at all engine speeds.
Mucked around with the carb a lot, probably annoyed my neighbours the most with the laps around the block, lol, jet changes and moding the needle got some small results but because of the poor quality of the carb was a loosing battle.
Then I got hold of a carb from a Yamaha Zuma scooter, the differance was night and day soon as I fitted it, instant response, idles smooth and easy starting.
It has now done almost 2000 km with no issues cruiseing at 38-40 kmh, I have had it up to 58 kmh, it would make 60kmh (around 35 mph) but it was reving hard and didn't want to grenade it.
I am runing it on 98 and Belray MC1 at 30:1, is expensive brew, but after the 4th barrel off inspection last week, (see sealant in pic's lol) it is worn (12 thou piston to bore clearance
) but just keeps on going.
Anyway sorry for the boring epic dribble on me first thread.
Cheers Phil
