The CH stands for Charley Horse, as the saying goes.
I never had any trouble kick-starting Harleys, but I don’t weigh 130 lbs, either.
This dude was tough starting on cold mornings!
My Yamaha SR-400 is kickstart only. I weigh 155 lbs. I have to be pretty precise with the compression release. It is less finicky than my BSA Victor 500 was in 1978.
I once watched a welterweight, leather clad biker trying to kickstart his 60’s Harley get tossed clean over his handlebars when the engine kickstart peddle kicked back. It was a hoot. The funniest part was he had to kick that damn beast about 12 times to finally get it running. Made me glad to be a Bonneville owner.
