A friend of mine has something similar - it is an old yosh cb350F racebike. It is mostly a junky old non-running racebike now but it has:
- yosh pistons (might be 380ccs)
- yosh cam
- yosh header
- titanium valvesrping retainers
- double coil vqalvesprings
- and god knows what other trick parts
it is a neat little bike and he keeps floping back and forth between selling it and keeping it and racing it in AHRMA or WERA but knowing him it will probably just grow more mold.
for some stupid reason those 350Fs are like roaches in NYC. All the hipster kids bought them and brought them in from other places. There are about 5 stockers I can recall off the top of my head in NYC, most parked outside.
As a former 350F owner, I think they are pretty but they are such a pig of a bike with absolutley no parts support whatsoever that I tell anybody considering one to run screaming in the opposite direction. For some reason and against the better judgement of many they have become cult bikes, probably because if you can't get something it just makes people want it more, and really you can't get much in the way of parts for these bikes. The bike really needs the 400/4's 6speed and extra ccs which is good because the 400 motor slips right into the frame. The 400 itself is a really cool bike though too and honestly I think the chassis is better.
