I don't think I've heard of a Hyde "867" kit?

The two normal Hyde big bore kits are 831cc (71mm x 70mm) and the long stroke 973cc (71mm x 82mm) both of which use modified 650 Bonneville pistons which have the same pin diameter as the Trident (.6882-.6885") but according to the workshop manual information, the 650 pins are shorter-even though the pistons are bigger.

67 x 82 - i.e. standard bore with long-stroke crank; I remember Norman advertising 'em.

Hth.

OK-as the only '867' kit I'd heard of, was the Routt big-bore kit.
So presumably, the Hyde 867 kit would have used standard triple pistons modified to suit?

Tbh, I can't now remember what Norman sold in the kit - whether it included his taller barrel suitably bored or, as you say, modified standard pistons.

I did always think it was a weird combination of bore and stroke.

Stuart,

What I meant was, that as the crank stroke is increased by 12mm and with the taller Hyde cylinder block, I wondered if the skirts of the standard triple pistons also required machining to prevent them from clouting the crank webs at (or near) BDC in the same way that the 71mm '650 twin' pistons have to be modified for use with the 1000 (973cc) kit? But it wasn't important, just me 'thinking out loud'.

Hi,

+0.040" (max. overbore) 71mm pistons, which sounds like you have oversize modified 650 pistons, that Les mentioned earlier in the thread,

Fwiw, this piston diameter with a standard crank is 855cc or with the 82mm-stroke crank is a gnat's over a litre.

Hth.

I've bored routt liners to .080" and used T120 pistons with altered valve cutaways and shortened skirts. There has to be better pistons available now days. Those T120 pistons use a wire type circlip, the T150 pistons use a worse type in my view which are square section with eyelets. If they spin loosly in their groove with any up and down play, they will break and come out, I had that with routt 867 pistons when I used T150 circlips which sort of fitted but were a little loose, probably because the groove was deeper and needed the correct clip or buttons, circlips need to be tight in the piston with spring tension so as not to pound up and down.
