When I had a C10 I only looked at it after the oil change. It never used any oil. Same with the C14. But a good idea with the light, though.
I agree- change oil, add 4.75 qts. Fuggetaboutit. Go 5,000 miles, repeat. Fuggetaboutit. Never had a Kawasaki use any oil no matter how many miles.
UMMMMM....you are posting this in the C10 area... so please, understand, that's a bit of an "overfill" for a C10...
there's a window to check oil level?just kidding Sig, nice job.
Just for shits and giggles, put the bike on the center stand when cold and start it looking into the oil window- and be amazed how long it takes for the oil to reappear and start circulating..
