re the rear wheel.... i just put my boot under it and lean back as i line the spindle up - makes it real easy - you can jog the wheel back onto your foot then push it forward.
i just attempted a temporary repair on my weekend fail. (snapped chain and smashed engine casing)

i cleaned up the area with a router bit, down to rough ally then drilled a load of holes and popped self tappers in to grip half a kilo of plastic metal.
still got to build it up a bit yet then retap it all proper and see if it holds.
the holes that were still left i drilled 15mm deeper and retapped to accept stainless m6 threaded bar.
should be ok tbh.
also noticed the clutch pushrod is a bit bent and pitted where it goes through the seal.... anyone got one spare?
picking up another engine tomorrow night which i intend to rebuild completely to a better spec than this one.... tony mon has kindly sent a sprocket cover to replace the broken one (cheers matey - top chap!)
*much later......
got 4 fixings in with longer threaded holes and longer bolts - good as its going to get til i build a new engine.
you can see the damage it's done to the steel plate that sits under the casing

riveted up another chain - not fitting the new chain & sprox though til the new engine is in, new pistons, powder coated etc... and the pyramid belly is going back on.
will let the skidmarx one go shortly
