Post Your Latest (Motorcycle) Oil Change!

What's the longest miles you've ever ran an oil?


Doubt the chain adjustment has much if any affect. I've never seen any difference in shifting after adjusting a loose chain back to proper slack.

Up down 3000km max on some SS1000 that I run in the past all with oil cooler beneath water radiator

today I change every 1500 on a small scooter I run because no oil filter and 800ml amount and on Tenere 700 every 2000 because I run on dirt roads (Motul 7100 10W60) otherwise if I not go to off road again 3000

For gearbox and smooth gearshifts mostly is the chain, never see a better gear shift because I change the oil from one brand to the other
Even on Honda that have tough gearboxes

I see the opposite. Never seen any correlation between chain slack and shifting quality. But I always keep the chain on my bikes correctly adjusted and lubed.

with this crf250 shifting improved after dumping the factory fill and going to 300v. Its been fantastic ever since and I haven't adjusted the chain once yet in 5000 miles. Its getting loose but I keep it lubed with Schaeffers roller chain lube and its not bad enough to need adjustment yet

Agree, I have seen zero correlation between tight or slack.

A chain would really have to be out of alignment to cause issues with loading the counter shaft sprocket to put that much pressure on the gear shaft.

3000 km correlates to about 1800 miles. That's such a short oil change interval. I would not expect the lowest performing conventional oil to fall off in shift quality in that time. That doesn't compute based on my decades of experience.

When the chain is adjusted and aligned, and oil is changed every 3000km/1800 miles, of course proper chain alignment keeps your shift quality from falling off, lol.

What bike do you run ?

2001 Kawasaki ZRX 1200, 140 horsepower, 87 lb/ft at the rear wheel. Engine mods increased power from stock but that's what the dyno says.

ok

That bike is Genuine Japan and bulletproof , not extreme revving compare to other.

In all years you run it did you compare difference between the different oil brands ?

Check out the UOA's I've posted in the last 9 years. Probably a dozen of them. So, yes, to answer your question. Search "ZRX 1200 or ZRX1200" in the title.

-What are you getting at with respect to "not extreme revving"? Do you know the bike I have or is that a generalization?

-Yes, bullet proof however what does that have to do with the shifting we are talkng about?

Low revving must look different to you... stock 10,500 rev limit.

-Mine has the ZX11 ECU and ignition rotor adapted to the bike, along with double valve springs from the ZX11/ZZR1200.

-Rev limit is safely upped to 11,500 rpm. ECU allows the higher rev limit, double springs keep it all under control at that rpm. A 2026 Yamaha R1 (998 cc) has a rev limit of 13,500.
I'm thinking 11,500 rpm limit on a 25 year old super standard that displaces 1164 cc is above the "not extreme revving" threshold.

5000 miles is almost 3x the OCI you are doing.

Anyway, good discusdion!
