[QUOTE=Barman;17931756]Short shifting is what rattles you out of a slumber at 3am as that empty 18 wheeler goes up and down the entire 10 speed shift range with the frickin' jake brake still on despite the fact that it's a 30mph zone.[/QUOTe1]
THose big trucks don't have even 2000 rpms to work with. Coupled with a close ratio trans and shifting every 300 to 400 rpms is a nessessity.

One thing you gotta love about The Perfect Line is that no matter how long you have been doing something or how successful you have been doing it, somebody will be along to say that you are doing it wrong.

It saddens me to learn of all the gear dogs that died needlessly due to my ignorance.

You just better shut the fuck up and listen to what the King of Cogs, the Dictator of Dogs, the Sultan of Short-Shift, Car94 has to tell all of us poor unwashed and unknowing retches, for we know not what we do to our innocent little dogs when we subject the little buggers to the utter brutality of the "short-shift".

That is nonsense, neither the gear mesh nor the pressure on clutch plate is in any way whatsover influenced by the RPM the engine is doing. Maybe you are confusing this with scooters that have a clutch engaged by centripetal force or something.

Thanks for having my back, But I never said I was an expert, just repeating what my long time Mechanic told me after he had to replace a shift fork, 2nd gear driven and drive gear and a few other parts in a old Suzuki sport bike I had. But doG forgive me for passing on my my experiance and the fact that I have never had any trans problems since then on any of the 6 bikes I currently own and all the ones I have owned since the Suzuki. I should have known better than to try and share with the all knowing Gods of the key boards with 80 gazilion post's you must be an expert! It works for me and I don't redline the bikes, I shift a little above the recomended shift rpm's for the bike I am riding!

Not the keyboard my friend, but 35 years of abusing offroad bikes says busting a transmission is very, very rare. What usually tears up a transmission is either crashing onto the shifter or "power shifting" under load without backing off the throttle or using the clutch. The former bends shift forks and the latter rounds off the gear dogs. Both cause false neutrals, missed shifts, stuck in gear and hard shifting. But in my experience actually blowing up a transmission or primary gear is normally a manufacturing defect not a rider defect.

Either the mechanic is full of shit OR you misunderstood what he was trying to say, because by recounting your tale of woe with your aged 'zuk, you further reinforce everybody else here that say's you don't know what you're talking about. (But, in your defense, you did state that you're NOT an expert) One would NEVER...........EVER..... bend a shift fork by performing the dreaded "short-shift". One bends a shift fork by being a clod, repeatedly forcing the trans to do things it does not want to do at times it does not want to do it. Either you, or if you bought the decrepit old "zuk used, would seem to have been doing wheelies and pounding the trans into 2nd trying to "keep it up". That's the way almost all sporty bikes that wind up with rounded off dogs, bent forks, and the like, have it happen.
ORRRRRRR, shifting without the clutch and not getting the timing just right!
And I must commend you on your powers of perception in realizing so quickly that I am a "God of the Keyboard" and an "Expert".

Not only do I have "80 gazillion" post's, I also have approximately 80 gazillion (OK maybe only 25) miles under my belt, with every kind of racing (except Flat-track & Drag), and I've never bent a shift fork and the only time I ever rounded off dogs was on my Gas Gas 250 because the factory never hardened the gears. I was the 2nd owner and they did something unheard of in the dirt bike world.............they replaced the entire trans free of charge.

er, plus one milliontythousand

Ride. Shift. Clutch or sans clutch, It will be fine. Unless you are a dumb-ass. Then it may not.

winter riding less than perfect traction, short shifting is mandatory so that you don't put too much power down

contrary to popular belief, riding below the optimal rpm range is NOT lugging

lugging is when the engine rpm is so low that your not pumping enuf oil to properly lubricate the bearings, and nothing to do with your rate of acceleration

Certain bikes, like my 950 KTM, do not like to be running below 3500rpm in 3rd, 4th ,5th, & 6th. Anything less on one of these, I think, qualifies as "lugging" because of the protestations of the drive train. If you have one, you know what I'm talking about.
As for "Lugging" the engine at so low an RPM that oil isn't circulating.........the thing wouldn't pull anyway, because it would have to be off. As long as the engine is RUNNING, oil will be circulating. At a lower pressure, but circulating none the less.

WTF?

Shifting at low RPM wears a transmission more than shifting at high RPM?!?!??!

Possibly one of the silliest things I've read here.

Put your tools down and step away from the bike.

Now THAT'S saying something, considering some of the, uh, "topics", that have been discussed on this forum.

we aren't all experts. it's just that some of us have a little bit of a clue how a transmission actually works.
