I've been doing a lot of research on lubricants (this thread is refering to motorcycle libruicants though I have done some research on personal lubricants as well ) and have decided that Royal Purple is the way that I want to go. At least for now... That said what is the general opinion of running Royal Purple Max Cycle everywhere vs Running Max Cycle in the engine and Royal Purple Synchromax in the tranny?

 

I read that it really smells foul yesterday...All I know about it. I use mobil 1...

 

I've been giving some thought to using Royal Purple myself. From what I've read here and elsewhere you can use the automotive version (20w-50 @$89.04/case of 12 qts) with no problems and save a few bucks over themotorcycle specific MaxCycle (20w-50@$133.44/case of 12 qts).

 

I ran royal in trans for about a year and it seems to work well except in hot texas summer. so i switched to bel ray 85w-175w and made a big diiferance , i can hardley hear the gears when shifting now.. as far as running all throut the scoot sorry cant help ya..

 

RP makes excellent products, and the standard "car" oil is fine for your HD and much cheaper. The MaxCycle has a bit more zinc and phosphorus, but the regular variant has more than most oils. Both have about about 250ppm moly, which is above average among the high-end synthetics, and the more the better within reason. MaxGear 75w90 for the tranny, but use a cheap fossil engine oil (non-"energy-saving") for the primary. No need for high-tech oil in that location.

 

I've been running it since my 1k and I'm happy with the product. MaxCycle in the crank and Sync in the trans. Works well.

 

There was a test done that showed RP is the BEST oil you could ever run. Ever. You will be surprised how some "highly recommended" oils on this board didnt do so well...
