Jackstand sitting on barbell plates backyard I know but worked great when I was putting new fork seals and gators and tire on my 750KO.
Now that's a good idea! Won't work with an oil cooler, but I'm not there yet.
I've always used a bottle jack under the leading edge fins of the oil cooler cover. This may make some cringe, but I've done it many many times for many years with never a problem.
What I've found recently is a 5 gallon bucket full of something, and a tiedown from the bucket handle oer the rear fender and back down. One 5 gallon full is not quite enough to hold the front wheel up. but plenty when the wheel is off. So I use the bottle jack along with until the wheel comes off.
2 5 gal buckets will hold the wheel off, no assistance needed. here I have 2 5 gal stacked. Old paint, and wallcompound. Tie wrap goes up and over my luggage rack.
Also, I've heard of using heavy bags, maybe water softener salt, on the seat. 2 = 80lbs, ought to do it.
