The old oil cooled inline 4 japanese engines from the early eighties are tough as nails and are comfy to boot. Heck, cheap flight to El Paso on Southwest, drink some beer out of Macs fridge and get home the next day. Think of the adventure. Imagine owning a bike that will never go down in value and likely run till we stop refining petrofuels in the distant future.
I have a 1982 Suzuki GS1000 engine in my life and not likley to let her go anytime soon.
