It's time to do the maintenance on my newly purchased K-9 and wanted to know what weights of oils to use. Anyone had good or bad experiences with a certain brand or weight? I plan on using Mobil1 motorcycle oil (has anti-slip additive for clutch) for the engine, transmission and primary. I was planning on using 20W-50 for the engine and primary...maybe 75W-140 for the trans. I have ordered the K&N oil filter and air filter as well.

I wouldn't put a syn in ur primary. You probably won't like it. I run Mobil1 in the motor, standard primary fluid, and Mobil1 75w-90 in the trans.
 
You'll get a thousand different answers on what to use.....


Primary- Bel-Ray V-twin Primary Fluid
Transmission- Bel-Ray V-Twin Transmission Fluid 85w140
Engine- Rev-tec 20w50 with half quart of Lucus Oil treatment (I have TP Rocker Boxes)
Have used Mobil One Syn. To much top end noise with TP's

Weight means: Winter starting @ 5w30: flows easier in the cold. Summer, you can thicken the oil during summer with a 20w50 for example.

Racing means: 0w30 is about the thinnest, parts spin thru it easier, less friction, better gas mileage. More noise at the top end where on the can it says, 'it takes a man' to enjoy that engine speak.

Clutch slip means: Convert to a dry clutch. Or, 'takes a man' to wait for the syn to breakdown if you want to gas it up no slip.

Takes a Man's oil: To understand all that racing heat and do you see engines breakdown caused by 0w oil? No. So extra miles, a tiny bit of noise, who cares about the weather is zero out the weight.

No chit :2thumbs:
If we were heads up, rally round the mileage loop, who do you think is going to win the argument is 0w summer/win and you following the thermometer?

:hi: WOTook ya? I'm already off the bike. One 0w after the other in 3 locations. And for those with the clutch slip, 1/2 ATF and 1/2 0w.

JMO is one more oily thread to slap your skirts, crunch your gears, slip your plates, you don't get it, not my crankcase we make a case or buy a case of 0. :cheers:

Did you run that runner up weight? :roll: No wonder you face look all :angry:, haole!
