Curious. Is there some secret addative in mc oils that helps them shift? Some oils shift terrible. My LTZ 400 shifts awfull. I have tried many oils. So far Napa Sae40 is the best.

I use to ride until a few years ago. My favorite oil until it was discontinued was Yamalube 20W40.

Nope, no magic in an MC oil that isn't in a HDEO.
If your straight 40 is working, keep on using.

its not just what is in the oil....

it is what is NOT in the oil...

No friction modifiers to hurt wet clutch performance..

and usually a modest amount of extra anti-wear additives such as ZDDP.

Make sure the back of the jug doesn't say energy conserving.

I've had good luck with Rotella 15W40 and Valvoline Motorcycle 10W40.

What differentiates a good shift from a bad shift? Grittiness? Time to engage?

There is no question that fresh oil changes shifting feel. I think I like the feel of heavier oils. And certain oils that don't shear quickly retain shifting feel over a longer period of time.


People who count on their fingers should maintain a discreet silence.

I think is viscosity. 15w40 seemed to last longer than 5w40. I could always feel the 5w40 get notchy after some miles. I think its how much a given oil shears.

even more than cars + trucks motorcycles beat up oil with their higher heat + shared gearboxes. most anything non-conserving will be ok but real synthetics + oils with closer spreads fare better, try a few until your satisfied with one. many use 15-40 cheap diesel oils but if you ride a lot longer lasting real synthetics can be a better value. always take your riding temperature into consideration for choosing an oil. my traded HD would not start on a big name 20-50 synthetic but a 10-40 worked well. i know use top of line 15-50 year around!

I have messed with adjusting the clutch for years now. Too much Freeplay to not enough. No change.

I'm concerned about it taking too long to pump up to the cams through that little skinny pipe.

Dont worry too much, I'm sure there will be no riding in frigid weather.
After sitting close to 6 months(maybe more), my r1 had a healthy amount of oil on the cam lobes, nice and slick. This is with 15w40. I would not worry about the oil taking a few to get pumped up. Plenty of residual oil to take care of things until then.
