Non GS, plain bearing crank advise

[Nessism]

Another odd observance, My Honda CB 1100 F, & my Kaw KZ1300, both have plain bearings & both I need to add oil between changes. None of my roller bearing bikes need oil between changes, & over the years, most roller bearing engines don't. Maybe to do with the difference in oil pressure?????

Burning oil has to do with rings and valve stem seals. Shouldn't have anything to do with oil pressure.

Even though I don't think is does anything functionally better per say, I also love the GS roller cranks - it's part of the unique character of the GS engines. The engines have a specific sound that the crank affords, again, very unique. Gotta love it. \\/

Haven't kept up in years, but the last I heard, the top fuel bikes still were using the roller bearing cranks, that should tell something, not sure about funny bikes, pro stock are required to use the original crank, for that model bike. I agree about the oil consumption, no pressure difference on rings & seals, but really caught my attention. Owned several bikes without oil consumption, then my first 2 bikes that have the plain bearings, both need oil between changes. Not sure about the Concourse. Friends brother-in-law "SAID", no witnesses, just idleing & I heard it tightening up tillit died, then found the crankcase full of gas & oil mixture. Decisions, Decisions. Thanks all
