Bazza's having a break but I'm just cutting back a wee bit by avoiding anything that looks like a scrutineering or rule thread or any shit fighting. This is what we need more of on the forum.
Anyway.....With the old B50 the KISS principle is the best plan. In stock trim they're a beautiful bike and it'd be a shame to change its appearance so much that it looks like a Cheney or CCM wannabe or worse.
Not that those bikes are ugly, far from it. It's just that they have their own particular look so why turn a B50 into something it ain't.If I had a B50 I'd concentrate most of my chassis effort on the forks and shocks. First up I'd change the 20" front wheel to a 21" Rickman or REH off a Rickman Zundapp or Monty which is both a better brake and lighter. They're pretty cheap on USA eBay and it keeps it all British. The BSA forks aren't that wonderful so fitting cartridge emulators from YSS, Racetech and others is a positive move. Many B50 racers replace the forks with either Betor (
Bultaco, OSSA, Montesa, Rickman and many more) or more expensive but not that different Cerianis. Shocks are pretty much down to whatever you can afford....You can get the best Ohlin, YSS, Reiger and others for $1000 give or take or you can do it on a budget with Works Performance, Progressive and any others for around $500. Of course you can buy second hand quality shocks for beer money and rebuild them yourself (Works are especially amateur rebuilder friendly).
The BSA B50 motor is one of the most durable and hot rodded in the sport....it's the small block Chevy of VMX. There are plenty of sites explaining B50 mods but like Huskibul said, don't even start until you get a copy of Rupert Ratio's BSA singles book. It's brilliant and in simpleton English...even I understand it
