Placed an order with Robinsons last night for the main bearings, plus a few seals, O-rings etc etc.... The valve stem seals were on offer as were the spring seats so I bought those too, I'm living off beans on toast for the next month!
Started to sort through some engine bits to find the best ones, cleaned a few bits up and placed them in. Found dowels, sorted crank bolts out etc! Got the gear shift about figured out now, seemed obvious when I took it apart, thankfully I have a manual.
I've stupidly put half of my good gear box in the mock engine which I bolted in the frame for the manc bike show so I need to strip it all out to get it! I'll do some measuring up for my air box etc first though, while its in one piece.
Been told from Robinsons one of my crank bearings has been ordered from Japan so it's a 2-3 wait for that.
Got a few more bits on the way including a base gasket so I should hopefully be able to work out the comp ratio and see how much my pistons need altering.
The bottom yoke is also drawn up ready, just needs a few hours of machine time and I may have a front end starting to go in.
The Robinsons order came through last week, checked it over tonight and I'm not best pleased. The main crank shells are nearly all scrap.
I have 4 halves in bags with part numbers written on by hand. One is either the wrong part or the wrong part number has been written on. I have a shell that's black and looks corroded. These don't appear to have the colour on either so other than a hand written number I have no way of knowing its size for sure.
I have 8 boxed halves, one looks good but all the rest have the plating missing/peeling off the back.
Very disappointed with Robinsons to be honest, I don't expect them to inspect boxed shells but sending shells out in bags is bad, especially when they're clearly useless. Its not like they're cheap either.
Install piston in bore with rings and a little grease. Push piston down a measured distance (1mm?). Check total volume with burette as you normally would a head. Subtract the displaced volume of the piston calculated from bore and stroke.
