Hi Mark and welcome.
If you're still having trouble with the brakeplate, could be a ridge (or build up of crud) on the inside of the brake drum, have you made sure the fulcrum adjuster (opposite the brake lever on the brakeplate) is fully unscrewed? (As others have suggested...)
Rocking movement isn't an issue with the roller-bearing big-end, I think even new ones rock (!) - as long as there's no vertical movement it should be fine (might well be OK even with a slight bit of vertical play for the use you're intending).
I wouldn't lose too much sleep over the marks/pitting in the bore either, having spent a couple of years running a VH with what looked to be horrible great digs in the bore - not only did it have feendish compression (hot or cold) it didn't use any oil! I've concluded that as long as there isn't a massive continuous plough-line the entire length of the bore it's quite serviceable :)

Back in the day, the Racers and Record-Breakers used to leave their freshly-honed barrels out in the rain.

The small rust pits trapped oil and helped prevent seizures under extreme conditions.

Embrace the rust pits ;).

Just looking at the piston skirt there seems to be some odd marking where it contacts the cylinder on the thrust face indicating that it might not have been machined properly . Also Honing WILL remove metal so sometimes it's a toss up as to whether you make it look pretty and have a slightly loose piston or leave it. I would measure THAT piston to see just what clearance it's running, and what shape it is. (Taper and ovality.) It is also a low compression piston. I see the flywheels are marked HT. Are they cast or steel? The LATER VCH (non roundbase) were cast and not really suitable for competition work and got a bit of a bad name for blowing up. Trials work isn't like racing though and heavier wheels help. Hope you are happy with your bike. There's always things to sort out.. Nev

Thanks again all,
I think, on reflection and advice, I will leave the bore alone. I will check and measure the piston this morning and if all is well just clean up and reassemble. Flywheels are Cast, piston is very low compression, 5,6:1 from what I can gather, I was actually thinking because I'm not using it for serious Trials but more Trail, to fit a new piston with a higher compression but maybe I will get it running properly first and get used to it.
The gearbox sprocket fitted is 16T and I understand the HT5 was, as standard, 19T and this would better suit my usage.
Thanks again.

I see steel flywheels, becouse the oilplug is inline with the bigend.

Hello Mark,

I run mine on 19-tooth crankshaft, 19-tooth gearbox and a standard rear sprocket - like a
350. I have the wide-ratio gearbox and for most things on or off road it works
well. For serious stuff i have a Vincent sidecar sprocket which has 56 teeth. With the
speedo drive off the back wheel there is no problem with the odo reading.

I'd check that the flywheel sludge trap isn't full, put it back together and ride it. It's
the best way to find out what works and what doesn't.

Thanks Adrie and Will.
My bike has the standard 18T engine sprocket which I will leave, what tyres are you using ?

Hello Mark,

Very elderly Pirelli MT43s - when I eventually had to replace the rims after the MOT man wouldn't
pass them any more I went to 18" for the rear to get a better choice of tyre.
