Looking at a 1200 Griso which has 4000 miles, 2016 but no evidence of any oil change since 2017 the first service. So, very low miles but if the oil is that old will it not result in a compromised motor with sludge?
I would check that it has been rollerised. I think that it may be one of the later ones so it should have been. Go for a test ride in any case. The Griso is a fantastic bike and quite rare in the UK. If you go for it change the oil and filter…give you something to do over the winter months…you may as well change the final drive oil and the gear oil/clean the gear oil filter while you’re at it too. Peace of mind is a wonderful thing 
. By the way welcome.

It’s only been standing 8 years, that’s not really that long, my Spada sat for 15 years whilst life got in the way, marraige, kids etc. I wheeled it out, changed the oils, the battery and tyres and have been using it for 15 year more with no issues.
The roller cams are something to look into if it is a 4 valve per cylinder engine, but by that date, I think they all should be good.

I agree with Larry (1) GRiSO is a brilliant bike (2) any GRiSO needs to be Rollerised if it was registered in 2016 it should be a 2012 build or later so should already have roller followers. When you start it check the oil light goes out straight away there were a batch of weak sump gaskets at first, that tear where the main high pressure oilway goes through the new (thicker and green) gaskets are cheap
It would be wise to expect to have to change the shock linkage bearings (pricey) and or the swing arm bearings (cheap) there are parts books on line to find the lates prices. https://www.motorcyclespareparts.eu/en/moto-guzzi-parts/2014-griso-1200-8v-motorcycles/connecting-rod-rear-shock-absorber
The linkages wear because like a 1990s kawasaki they have no grease nipples, are low to the ground and sprayed by the rear wheel. When available new they are ÂŁ500-ÂŁ600 but that is usually cheaper than the individual cost of 7 bearings, 3 centre bushes and 8 seals - whch then have to be pressed in

Curious to learn what “evidence of an oil change” actually is.
In any case, I wouldn’t be fully firing up a new purchase (the seller might, before you hand over the cash!) without first dropping and changing the various oils.
I think that it’s the one for sale at Wigan Motorcycles…They say that they’ll give it a full service for the buyer so happy days. I’d also get them to confirm the rollerisation and do the other maintenance stuff that’s been mentioned. By the way check out GrisoGhetto…it’s Australian and a valuable resource. If I didn’t already have a Griso I’d be tempted

I assumed paperwork / invoices 
- as well as, I keep a log of when jobs were done.
I agree though if unknown, change oil anyway, even if it looks alright.

Thanks all for your input its very helpful. Had a Griso before and as an 09 it needed the upgrade. (ouch!) I’m impressed with the speed of your responses and how useful!
