Topic: Speedo cable leak 59 VH

Weeeell, the very slow weep from the speedo cable doesn't pee me off anything like as much as the perpetual mist from the exhaust lift lerver that slowly but surely turns the whole top of the engine into an oily mess! (I've tried new washers, and O-rings, the only working solution so far- also in 40...

My BM has got beautiful and very sophisticated rubber O-rings all over the engine joints. I always put it together oh so very carefully. And it still leaks. (OK, so it takes more than the first long run but I no longer lose anysleep over the drips from the Ariel :D )

My R100RT BM suffers from valve seat recession even after fitting 'unleaded conversion' valve seats. (Additives like Valvemaster Plus make no difference). Didn't have any problems at all when it was running 4-star. My theory is that these days no-one apart from me actually rides one regularly for an...

Graham: With the clutch cover off and in neutral, pull the clutch in while prodding with the kickstart and check to see if the pressure-plate is freeing off evenly. It does need a bit of an 'eye' but if you can line up the edge of the pressure plate on something you can get an idea if it's spinning ...

Dave:I seem to remember sae 30 for Huntmasters; might be 40 for summer and 30 for winter. It might be OK with a 20-50, with all due respect to Steven I wouldn't use a cheap one, I'd need an API spec on it - SE minimum. I've been using Comma Premium 20w50 in my old BM (air-cooled twin) for years (mai...

I think the spout should be about 1/2" long - what matters more is whether it's still got a proper 'drip' on the end. otherwise the oil will just run down the back of the chaincase. You can re-form/renew them with plastic padding, or maybe araldite/JB Weld, filed to shape when hard, Or for a mo...

There's always been a touch of the 'black arts' about engine breathing, I seem to remember something about people putting big breathers all over Vincent V-twins and massively increasing oil consumption. I've also always been curious as to why the original Ariel timing-chest breather with a nice valv...

I've heard that soap or shampoo is OK but washing-up liquid isn't as it's got a high salt content.

The only other thing I'd add is make sure you get the tyre bead into the well.

Hi Pete ! I sit here with a pair in front of me - drive side right hand thread, gear side left hand thread. I tend to put the flywheel in a vice (use soft-jaws, bits of scrap ally or even paper if worried about 'bruising' the flywheel) and use a socket with a long extension bar (old Matchless fork l...

Every time I've used multigrade I've ended up with a siezed piston, stick with monograde!
