Guys and gals:

I've been conversing with the Veg and early on with Vonnie on this, but I want to put it in front of the membership. This is really bothering me, and I'm pretty sure it's not normal, so I can expect to deal with it in depth sometime in the future. I'll try my best to describe the issue, then please, ya'll help!

Runs out fine, no issues with clutch, shifting, etc. Picture yourself running along, sixty-ish in some traffic. The bozo in front of you piles on brakes. This is no big issue with you, cuz you're plenty far back. You just get off the gas completely, and start looking for the next move, whatever it may be. The throttle clears, the gears mesh and you are backing down good in five, no worries about a wreck, then whaaaammmm, it feels like you just downshifted to fourth gear. But you didn't. You're still in five, and the rest is just like it should be. Go to four, no problem. Back on the gas in five, no problem. It feels like some sort of horrific gear lash, but there is no reverse reaction, in other words, when it does it (which is every time you get off the gas in five), you can get right back on the gas and it doesn't lurch in the opposite like lash going back the other way. My earlier descrip included a reference to a hot rod Camaro with a shift kit dropping from three to two. This is exactly what it feels like. No noise, nothing overtly rude or sharp about it; feels like an auto tranny with a shift kit in the routine of downshifting. It is a soft shift, but VERY pronounced, and VERY noticeable.

Any ideas or comments would be very much appreciated. Thank you all, and happy holidays.

Hang up in the paralever rear end? Is this a lurch in the bike suspension or is it a definite increase in engine braking force?

Can you try an experiment? Go up to speed in 3rd or 4th then back off and gently apply the the rear brake. Any hint of the problem? Second trial is to do the same but only partially back off the throttle to slow down and see if you can duplicate the forces of engine braking in 5th. If it is a binding in the paralever (or whatever the name of the rear suspension is) that might show it up.

If it is the transmission, it's slipping out of gear and then back into the same gear. IE, it doesn't stay in gear when driven by the rear wheel, slips out and then wham (as you said) back in. Bent shifter fork or worn dogs.

5th gear is an unusual victim for this, but it's the classic M93/94 5-speed problem. Read about it here:
