Re: Ariel tricycle

By the way, young Nixon's first name is one of those English peculiarities: "St. John". It wouldn't be too peculiar if it were pronounced "Saint John", but I think it's more like "Sinjun". Happy to take advice from speakers of the Queen's English. Leon "Sinjun&quo...

Is the spring you need bushed at both ends ??

Some have a bush at the leading edge but the rear is hooked through a pair of rollers to allow for the extension as it flattens under load - no swing shackles involved.

What are the dimensions ???

Re: slimming down leaf springs ?

Eat this :lol: :lol: :lol: Nice one ;) . Another thought . . . I recently replaced the front springs on my Ifor Williams HB510 Horse Trailer . Its a twin-axle with a gross weight of 2584 Kilos. The front nearside cops all the sunken drain covers, broken kerbs, rocks at the side of the road and so-o...

Re:

I hope you have a big Angle Grinder - I wouldn't use a 115mm one for that ! If the springs are too firm (after slimming) I have seen people grind as 'waist' into alternate leaves to make them more flexible. I believe Mr Bradshaw designed that into the leaves on his early P&M Panther rear suspens...

Re: Sq 4 oil pressure

Way back when I rebuilt a four-pipe Square Four, I used to get 52 psi when cold which dropped to around 5 psi on the road when hot. The problem turned out to be the pressure release ball valve in the front crankshaft. A new spring and properly seated ball cured it - 52 psi when hot at road speed. I ...

Re: Italian rally May 1

Now that would be interesting to see.

I was intending to go to the Rally on the '58 VH, but No. 2 daughter is due to pop No.2 Grandchild on 4th May (her husband is a 'Star Wars' fan !) so I'll regretfully have to miss it (unless she is early . . . . . . . . . . . 8-) ).

Re: VH 500

One of the things that has annoyed me ever since I got Albert was how precariously he sat on the sidestand. It wouldn't stay down without the weight of the bike on it and the smallest nudge was enough to flip it up I believe that legally a sidestand has to retract on its own if it doesn't have an e...

Re:

Have you tried 'British Only Austria' ??

The ad' doesn't say what the compression ratio is - but it might be worth an e-mail ??

(Unless you know from the Part Numbers).
