so an official update
Progress!
first the frame went on. I replaced my missing frame spacers that I carefully archived with my lost odd socks, with that from the 900 I bought. I knew there was a reason I dropped $3500 - for spall pieces of aluminium.
after much dicking around, we discovered the 17mm front axle is the perfect tool to drift in the swingarm seal retainer, seals, and bearings. this was only after grinding down one of my sockets on Koko64's benchgrinder, after I nearly got it stuck in the swingarm bore inside the engine
I think the first seal took 30min to get in. with one side done, the other side's retainer, 2x seals and 2x bearings took barely 10min, with the newly discovered multi-tool. the axle pin fit well in the first bearing, to act as a guide for the rest of them, whilst the larger headstock which gets clamped in the front fork does the drifting contact, with 0.5mm to clear all around. perfect
we also pumped 5L of grease into the cavity between the two bearing sets, to avoid the reason I had to replace this swingarm pivot pin in the first place - water penetration, causing rust and bearing failure. this may or may not have been done with a syringe stolen from my son's medical supplies. good thing Mrs Nibor doesnt frequent the forums
as a bonus my increased top speed should allow Nugget to outrun even a greased scotsman!
