I know from experience, with enfields, that this is a seriously good brake on them.

Does it fit into a half width hub ?
It looks like your torque arm is for the full width stuff ?

hee is where I got VH main bearings from, in the last year

Update Spent a while last night removing head gasket and then lapping the head joint (took ages). After all that lapping, I suspected that the push rod seals were too porky (now trimmed down somewhat), as the club push road tubes are slightly longer than the originals, and weren't letting me clamp t...

I've tried a variety of ignition and carb settings - retard, advance, flooded, choked etc. I am confident it's timed on the compression stroke and that the timing is thereabouts. On a lighter note, I've found the compression issue - the head gasket on the push-rod side is leaking. I'm a 52 model, so...

Recently assembled VH500 New mains, new big end, new rings, new carb (amal concentric) and mag rebuilt. timing is good. spark plug will spark against the barrel (tried a couple now), valves have clearance at tdc, lifter disconnected. Compression isn't brilliant, but all the kicking and a drop more o...

I'm running the right parts.
I'll carefully take the first tooth down a little more and keep trialing

I have the cover off and the quadrant in it's bush, on the inner cover, so I can see what's happening. I found another quadrant and that has exactly the same issue - the first half tooth jams the ratchet, depending on position. The ratchet gear looks fine and in consulting the parts list I can see t...

1951 BA box with some new internals. Kickstart would lock or jam every 10 kicks. The box is free and it appears that if the kickstart quadrant meets the toothed ratchet at a certain position then it catches and locks. You can rock the engine, in gear, everso slightly and all is good. The first tooth...

When I switched from a singleport 500 to a twinport, the drop in performance was noticable. Not as much as what you seem to have experienced however.

However, i'd already invested in a new exhaust system ... and now the single port head/barrel is on another bike.

I wish I'd thought of that ....
