Ya mean all I heed is a bit of polish, paint and varnish that could be mine.......
Back around 1971 when I was much younger I rope started my 1350 for several weeks waiting for a starter from the dealer. Piece of cake.
Back Illinois, 74 Switzer/new XS1500. In like 78, did some side dead end channels explore with the GF, Fox Chains of lakes. Battery not so new, lotta idle, and motor quit. Wrap, hat off. Grab a ski rope and wrap it up. Told the GF to duck so no whiplash. One foot wet well leverage, a mighty tug, and swear started so fast fell back and got wedged between the front seats!

At the 1966 Orange Bowl 9 Hour race a 19 year old me pull started a Merc 1000 at least 7 times. We broke the battery and the starter wouldn't turn over so I was pressed in to service as engine starter and riding mechanic for over 7 hours. Ronny Russel and Ron Cherry did the driving.
I saw my uncle rope start his 1100 several times and a 1350 on a bet.
Actually just because its a big motor the physics don't change. Only do compression one piston at a time, so actually takes no more effort than a lawn mower. AND its a 2 stroke with little mass to rotate ( valve train, cam on valve springs compressed a 4 stroke, massive crank, etc). Bet you could rope a V8 2 stroke..
( I can prove mass and high compression 4S as no WAY you could EVER "rope start either" my Harleys)
The drag of the pistons and rings DOES change when things get bigger. Drag a quart paint can thru mud vs a 5 gallon bucket.
That kinda what I meant..nice analogy. And drag is friction. Kinda what I tell people that a surface prop will be faster if set up right. Simple go into the water mid chest deep and swing your arms up and down. Lot tougher in water than air. Back up waist deep and do same.....Mass and fluid resistance.
