Buy a r1100gs that has been under a cover in the road for 4 years

Hello

What work would you do before starting a bike that has been sat outside for 4 years. Lets skip the drain the tank, replace the brake fluid and charge/replace the battery.

Would you remove plugs, spray two stroke down the bores and turn over through the gear box. Then start bike, run till warm and do ano oil and filter change, What about the grea and final drive oil?

Check if there's anything living in the airbox.

If the idea of the 2T was to soak/lube the rings and bore would that work on a flat twin?

I'd ask on a BMW boxer forum as I don't know if there's anything specific to re commisioning a BMW boxer.
In general,with any bike that's been stood I would get it turning over with the kick start or through the gearbox first.

What others have said and..
I'd want to check the entire electrical system and connectors for corrosion.
Brake calipers are likely to be seized. Down to luck if they are even useable.
Fork seals will have hardened and will leak.
I'd not be that keen on using the tyres in anger.
It would need to be very cheap to get it useable,otherwise you'd be better buying a dearer one which has been cared for.

I'd expect the clutch to be stuck together and be really careful when first putting it in gear.

From my experience of an 1150gs that hadn't been sat under a cover for years... check the electrics. I can't recall if canbus is on that bike or they added it to the 1150. However if it has ABS then check everything very carefully.

CANBUS is only fitted to the R1200GS and later bikes.

You sure? I thought that my 1150gs had it. Could be wrong, obvs.

Yep. The R1200GS, which was the first of the "hex-head" models, came out in 2004, I was buying my first 2 Rocksters* (R1150R-Rockster) in 2004 so I was in and out of the BMW dealerships a lot, and discussing stuff with them almost every week.
