1980 900 SS Questions.
Bike in question is a 1980 900 SSD. I pulled it out of a garage in the mountains of Colorado from the original owner, with 10,000 miles on it, parked in 1984 on the original tires along with everything else down to the bill of sale from the dealer and every single service record, tool in the tool kit, and manual.
It's getting the normal treatment of fuel lines (green), fuel petcocks, full carb rebuilds, a bunch of misc old rubber pieces, oil and filter, tires, brake lines and caliper rebuilds, exc.
1) Oil. I know, I know. Everyone's favorite game show. Oil threads. But, searching resulted in no newer information and some conflicting results. So. What oil is everyone running now? I run Castrol 20W-50 Non-Synth in my BMW Airhead and K. I see recommendations for straight 50, which for Phoenix isn't a huge deal but it's still not my favorite, and recommendations for 20w50 non-synth. Can I get away with 20w50 Castrol on 1000mi oil changes?
2) Carbs are obviously PHF 32's, what size float needle valve are people running? 250? I'm ordering the kit from BevelHaven with the choke assembly as well.
Thanks in advance, here's the bike:
