Re: More questions than answers

Weeeeeell....
I think a lot of us just take the tappet covers off (not the rocker boxes, just the roundy caps for tappet adjustment ) and pour a bit bit.
That way it goes down over the cam and followers before finding its way into the sump.
Don't get carried away - remember these are a dry sump ...

We're trying to organise an Ariel presence - anyone planning to go on an Ariel?
(Or even planning to go? :roll: )

I've not been able to ride the Huntmaster since last summer and it's not got its 'motorway spurs' yet so I've not got much ...

Re: 58 VH 500 popping out of second gear above 2500-3000 rpm

Probably worth checking, although you might have done so already. There are two pins that engage with the selector drum, are they worn at all?
(A very long shot might be the drum itself worn, but I've never come across that, only worn pins).

Re: Pushrod rubber size how much to remove

Iron head? I always just crush them down with tightening the head bolts. (Even the original Ariel ones - from my Ariel gasket sets - are much too tall).

Re: Otto Head gasket installation.

Otto gaskets - have you seen the MkII doc Roger posted here:
viewtopic.php?p=101629
(It seems to have new-install figures as well as re-torque.)

Not Otto gaskets - but what's happened to that shock-absorber spring retainer. do they often do that?!

I can only refer to 'Tuning for Speed' (Chapter 1, 'A Preliminary Survey'):
'...another (point which needs to be watched closely) is whether the rod or cage shows any tendency to work over to one side and bear heavily against the flywheel. The latter state is a sign that the roller-cage slots ...

Re: Two stroke oil

Gene
On this side of the Atlantic VR1 is a 4-stroke oil, you need a 2-stroke oil - one of the Valvoline 2T types?
You should easily be OK with 32:1 (or higher - I think some guys here are using 40:1) with modern oils but you'll have to decide on mineral, part synthetic or full synthetic! (There are ...

Re: Leader Sreeen

I've never had to remove one myself but I'd think it's nominally quite easy - 6 screws/nuts across the top of the' front shield' panel and the 2 nylon eye-bolts that attach to the tops of the supporting stays - if it's a new screen it should all be fairly recently put together and should have a very ...

Re: Mystery chain case hole '54 NH

I think you're using a '56 bottom end in the NH, it should have the longer drive-side mainshaft (allowing the chain line to be moved outwards to give clearance for the FERC behind the primary chaincase).
Did Geoff give you a 56-on gearbox with the longer gearbox mainshaft to match with the ...

Re: Mystery chain case hole '54 NH

Apart from the chaincase inner the rest of Dennis's bike is 1955?
(Oh dear - cue discussion on gearbox mainshaft lengths and drive-side engine mainshaft lengths?) :roll: :twisted:
