Re: Primary chain tension - '58 Huntmaster

Hi I think you are referring to this one, which is the facility to adjust the gearbox position once the pivot / clamping nuts and possibly the secondary chain have been loosened: GB Adjuster.png If you've changed a head gasket on a Huntmaster adjusting the primary drive is a doddle. Regards Mick

Re: Valve covers on Black sidevalve

Hi

Can't help with what they're called but the best penetrating fluid , in my experience, is a 50/50 mix of ATF and acetone, (WD40 is not a penetrating fluid in my opinion).

Re: FH650 - oil question

Hi On my 58 FH there is a level plug just below the rear of the bulge which caters for the shock absorber. That said, I don't use it preferring to set the level to just touch the chain by looking down through the filler port. I use Castrol XXL SAE 40 in the primary chain case gearbox and engine. Reg...

Re: Heat proof paint

Hi

I use matt, it's more efficient at heat dissipation.

Simon, I've measured the temperature of my FH at the head / barrel joint below the exhaust at 260 centigrade - not sure engine paint would cope with this.

Re: 7" half width hub brakes

On my wish-list: a solder pot and a tool to open out the end of the inner Hi I made a bird caging tool out of two short lengths of steel angle, drilled through then counter drilled - works fine.

Re: Positive or Neg earth on 55 huntmaster

Hi Yes, from your description, the bike is wired positive earth and I believe that is per original design. Normal filament 'bulbs' don't care which way they are wired so don't worry about it being blown, probably the result of vibration. Replace the bulb and start the bike observing the ammeter - li...
