This is our recently restored Yamaha AS1 from 1970. Unlike earlier restoration where we've fixed the bikes both cosmetically and mechanically we settled for just restoring the bike mechanically using as many of the original parts as possible and a lot of cleaning and polishing.
The bike looks ok given the fact that it's almost 40 years old and had been driven for over 14000km before the restoration. After the mechanical restoration it runs beautifully, it starts with the very first kick, runs smoothly in idle and revs well. A quick pull of the throttle sends it up on the back wheel, not bad considering that it's a 125 cc bike!
Too see the restoration of this bike and more go to www.yamaparts.com!
@romaurie I bought a new YAS1 in March 1969 & ran it on NGK B9HC plugs which were fine for continual high rpm use. The problem was that a lot of dealers did the ignition timing with a strobe which for a high performance two stroke is no good, for precise timing it must be done with a dial gauge I never had any problems at all apart from a loose baffle in the LH silencer which was replaced under warranty ...happy days.

Brings back memories, I could only get my 1972 AS1 to keep Champion L87Y plugs instead of eating NGK's.

I have nearly no knowledge of combustion engines or their mechanics, but I'm interested in learning. I have lots of time and a little money. I thought restoring an old bike Japanese bike with fairly simply designed engine would be the best way to break my teeth. Can you recommend some types of Yamaha's, Kawasaki's or Honda's that I could find for fairly cheap and would have plenty of parts available on the internet?

I bought one of these 1970 same colour.A friend got a blue one.Great bikes.Every 2 weeks the company we bought them from, The Rayspeed Robbery shop in Christchurch, Hampshire replaced the sparking plugs because they ran too hot and melted.So NGK kept coming up with "cooler" plugs.I really don't remember them ever fixing the problem before I traded it in for a BSA A.10 650 when my parents were on holiday.My Dad noticed after a couple of days the bike was different, but told me not tell Mum.
