Why is this oil rated only for motorcycles? Won't it perform as well as previous Castrol 20-50 synthetics in my bal. and bluprinted auto engine?

It is not for Car engines. It is formulated without certain friction modifiers to keep wet clutches gripping. Oil change intervals for motorcycles are closer together for this reason. Do not use it in your car.

How often do u change synthetic oil. In 2012 Flhtk?

I would stick to the 3000 mile change as called for in the owner's manual. I know some people say you can go longer with synthetic but I would not. Saying that, much of it has to do with if you do a lot of stop and go city driving vs to hwy, in town driving can stress the bike more than hwy. Oil changes are cheap in the big scheme of things, you should always check your oil and alot can be told by the color and smell. Hope this helps, drive safe.

Will this oil work for both a ducati monster dry clutch (m900) and wet clutch (620 dark)? thanks!

The dry clutch doesn't get engine oil so if the engine is recommended for full synthetic there's no problem for the "dry" clutch. As far as the 620 goes if the mfr recommends full synthetic then go with it.

V twin blood

Harley twin cam 88 seems to like it runs quieter, I think so anyway, like Castrol oil but hate the foil seal on bottle,my advice is to use a funnel with screen! you don’t won’t any mishaps with foil in oil tank.
