I don't keep a record of what I spend on the bike but here's what I've done. All the miles have done by myself.
The bike lives outside under a cover and gets washed occasionally. never been on an optimate or pampered like that. She's been ridden in pretty harsh environments and everything from + 50 degrees to -10 degrees and has never failed me out on the road. She's been hammered up and down the Dalton Highway 4 times, been on some pretty tough dirt roads and just soaks it up.
Serviced by Clarks until end of warranty then fettled by Steptoe, Jonno at ABW and myself.
Final drive propshaft failed at 19k and changed under warranty
2 FD rebuilds. The 1st at 73k because I thought I should and not because it was knackered. The 2nd at 90k because the rear wheel went out of true on an Alaskan trip last year and it was 10,000 miles before I could get it sorted and I just figured that there must have been bearing damage in there.
Clutch change at 73k again because I just figured she needed it. Turns out the plates were about half worn.
Gearbox failure at 73k and second hand one bought from Sherlocks. The dog clutch failed and destroyed the innards. I've not heard of this before or since.
3 batteries and now on a Motobatt. None have failed though and I change them when I detect a weakness on starting.
She is on her second set of discs and I think I'm on my 3rd set of pads which are still good after 3 trips to Alaska and about 30k.
I don't standardise on tyres and shove on whatever I can get at a good price or used off here. I have K60's on at the moment which are superb but have a set of second hand Dunlop Trailmax sitting here ready to go on as and when.
I always use Putoline 20/50 engine oil and change it every 6/8000 miles as well as the FD oil.
I have Ohlins suspension all round and a power commander 111 which is set up for lots of torque.
That's about it I think
