In higher gears the ratio is not so much in your favor and it takes more work. It's pretty much the same reason that if you have a worn clutch, it's most likely to slip in high gear

Eh....I think the reason most people experience clutch slip only in the higher gears is because those are the only gears they go WOT in......They're too pussy to go WOT in first :lol:

I was just assuming that 1st puts the most stress because it has to overcome momentum from a dead stop. You know how when someone needs a push start, and a bunch of guys start pusing on the car until it starts moving? Well, it's hard as hell to get it moving, but once it's moving, it's pretty damn easy.

I never said it was a cause -> effect relationship, I'm simply showing my personal experience. The guy who did the rebuild listed a number of factors, but I do know the previous owner put it on a dyno straight out of the box. The new top end has hardly coughed up anything.

That's either an assembly error, manufacturing error, or the person doing this "Hard break in" didnt know the difference between "Break in" and "Abuse".

It's my guess that most people doing a "hard breakin" don't know the difference either, including the guy who had my Husky.

WOT and low load redline are complete opposites you can low load redline any bike in 1st without fear of a wheelie....takes what seems to be forever to get there, bcause you're cracking the throttle just above idle to GET there, but it's how I've seen a few engines "broke in" after rebuild...especially 2-strokes :idk:

On a bike this is pretty much true but that's how you test a slipping clutch in anything.
