20-50w anyone?

Hey all.

I just put some 20-50w oil in on the last change to see if it would be better.

Bike just turned 30,000mi and in my cars I usually switch to a thicker
grade at 100,000mi, so, I thought Id give it a go..

It has made the engine sound smoother at idle, no difference otherwise..

Looking for any input on the good and bad of doing this.

20W-50? (For, 20 viscosity winter, 50 viscosity, otherwise.)

Not a problem, above 32 degrees F., ambient, according to Kawasaki Owner's Manual:

For some reason, I did happen to note that the drain plug torque is different in the materials LoneRider provided than those for my 2009 model. My manual calls for a torque of 21 ft.-lbs. rather than 16.5 ft.-lbs. The material LoneRider posted is obviously straight out of a KLR owner's manual.

Is there really a difference in the drain plug torque across the years? Doesn't matter since I only own one year of KLR, but I never knew that.

Could those 4.5 ft.-lbs of torque result in stripped threads for somebody assuming the torque is the same across the years and applying 21 ft.-lbs instead of 16.5 to an older model? Just a thoughtSorry to distract. Just thought I'd mention this.

Anyway, as noted, it would seem your environment would certainly be fine for a 20W-50 oil.

My last two changes were 1/2 Rotella 15w-40
mixed with M1 15w-50. Joked about running
semi synthetic 15w 45.

It's a thumper and the botom end takes a pounding.
Nothing wrong with a heavier oil cushioning the
crank bearing.

The whole 10w-40 thing never set well with me either.

Next change will likely be dino Quaker or AZ 20w-50
for the bulk of the summer mileage. IMO the Mobil 1 was overkill.

I use Rotella T 15-40 and change every 1-2K miles. It is motorcycle rated and holds up to the extreme shear of our bikes.
