it's an Ariel frame, box stock. Probably originally from a 500cc single but it's hard to say, all heavyweight Ariels used the same frame post-war. Forks are Ariel, wheels are BSA.. but I will be changing the forks for BSA ones to simplify assembly.
gearbox is from an A10 BSA. Belt drive and clutch is a Tony Hayward unit which used to be on a roadracer at one time; front pulley is a special item using thr Hayward tooth ring pressed onto a turned-down pulley from 45 Depot ( because the belt sizes and types didn't match - HD clutches are bigger than BSA ones and the tooth profile is different, too ). The whole set-up caused no end of problems but I'm pleased with it now it's done.
oil tank is, well, something I had in the shed, 1980s Paughco Mustang tank the same. Footboard hardware is a mixture of NOS and 45 Depot stuff, including a Servicar left pedal and side rail.
bars are currently 1" items from an HD flat-track XR750, clutch lever is an original HD front brake lever - but I will probably go to 7/8" bars and repro levers to make it easier to match the cables up.
so, we now have a rolling machine with all the bits in line and clearance for the things that need it.
the motor mounts were a subject of much discussion. The mounts you see are the second set, which include a fotboard mount which in the event, hasn't worked out. Don't know if we will use them, there are 3 different sets. Aim is to finalise them and then weld them into a solid box section, rather than the present bolt-up configuration
There is an engine packed away, with #6 heads, WLDR cams and stroked to 54" using T&O flywheels and pistons. After much discussion with my engine builder we left the baffles in, which I'll be interested to see how that pans out. The engine in the bike is a spare unit which wil probably be rebuilt when I have time and funds.
that's about all for now
