    I'll try that. The head is CNC machined so unlikely, the cylinder block is cast (but machined faces), maybe, accumulative tolerancing from rod and piston? I'll take some measurements but won't lose too much sleep over it, I'll machine them right anyway.

    A new page, I'm not sure how to make pages longer, post less?
    Anyway, a page without pictures is crap. I took a nasty injury from a piston circlip under the fingernail today so I'm treating it by sipping the Rhubarb gin that has been living in the garage for a few weeks. Very enjoyable!!! :pimp
    I am left un-supervised tonight....

    Can you post up a couple pics how the chamber fit in the heads please?

    I have a jar of Bourbon and Cherries in the fridge a riding bud gave me for use of my NoMar. Mmmmmmm. You put any sugar or other in? Rhubarb is TART!

    Here's a really technical question - do you suck on the rhubarb once the gin is gone, or make a crumble?

    I make the occasional jar of morello cherry (cheapest lidl own brand) vodka - they aren't much use for anything else - and after everyone is paralytic, I make a boozy clarfoutis.

    Does the rhubarb gin look less like piss once poured? - or do you drink straight from the jar?

    @Bigbore4: the morello vodka I make and also the sloe gin that is fairly commonly made at home here, from the fruit of the blackthorn, is usually sugared. The amount depends on how sour the fruit, and what your intended outcome is. The vodka ends up sweet and I use it as a digestive or liqueur. Roughly equal weights of fruit and sugar.
    You will not be smitten down if you try other ratios.

    Straight from the jar red neck style tonight, I can't comment on much else tonight. Like the sound of the crumble, temp may evap the alc though so probably go for suck. Hang on, I'll go to garage and try one.....

    We wouldn't expect anything else - a true pioneer and willing experimenter.

    The clarfoutis does loose the most of the alcohol, but the taste is sublime. Sufficient hint of naughtiness to excite...!!

    No Gin tonight....:fishie

    Two piece manifold allows the balance pipe to be junked, shame I quite like it, especially with a boost chamber....

    O'rings seal it up with a little vac grease.

    Two small countersunk screws hold the two parts.

    A bit of work to match to the reed blocks. Have done that now with a craft knife and also smoothed the joint between the two ally parts.

    So before I go for a 1.4mm squish I Email Roger at Wicked ATV Ca.

    Hi Roger, my 421 Serval parts all came through to the UK from my friend in Ca. Engine is coming together really well thanks, one question, what squish clearance would you recommend for this motor using 95 or 97 octane pump gas and road use in a bike?
    Thanks.


    Alright! that's good to hear. Anywhere from .036-.050 is fine. 165 under ibs of compression
    Thank you,

    Great, thanks. I got one measured at .041 and one at .047 so I'll machine the smaller one up to .047 to match.
    Cheers.


    So there you have it :deal

    Dome fit...like this with O'ring....

    IMG_2225.JPG


    I'm going to build up and fit rings, torque down cylinders and then measure squish. Further email from Wicked questions the difference between pots and I agree, I'll make whole rings of solder to drop in to the bores to measure proper. So now measuring and adjusting ring gaps.

    Like the rings of solder, I thought the pistons could rock fractionally if "squished" on one side!

    Indeed...
    Double check it. because they are both machined at same time. possible piston just rocked forward

    You have to be on the center line of the wrist pin or it will cock. I spent a short stint working on large 2-strokes (EMD). We pulled the inspection covers, and inserted a tool holding a piece of lead wire on either end through the inlet ports. Turned to align with pin and barred the engine over. It was a good way to quantify wear in the entire power cylinder.

    @Wildebeest90210
    Thanks for posting those pics. It's now clear how it works. Pretty cool. And as big a PITA as it will be I agree with your vendor on assembly at final torque to make this measurement.

    ETA not sure I would use a ring. I would use 2 pieces, opposed on either side of the piston on the wrist pin center line, held in place with a dab of assembly grease like Lubriplate 110 or similar. The ring might be too much to crush easily.

    what he ^^^ said. In regards to just using two smallish pieces in line with the wrist pin. One on each side to prevent even the possibility of rocking in the wrist pin bore/rod.

    Technique I use is a single piece of solder bent into a kind of 'omega' shape. Top loop on front of piston (but not into squish band) and ends over and parallel to the pin.

    Clever, keeps it from moving during head installation and removal, but only gets squished where it needs to be.
