1997 R1100RT, 60K Miles, Harsh 1-2 Upshift, 2nd comes out of gear, once and awhile.

About seven years ago I saw a rash of skipping transmissions (nearly all were M94s skipping in 3rd) and now I'm seeing it again but they are M97s skipping in 2nd. This is simply the situation: these transmissions aren't the best. The M97 in my wife's GS sounds like a Mack truck but has covered 150k miles without being opened, but there are plenty of them that aren't that lucky. The input shafts deteriorate and the gear dogs - even though they are undercut - start to go.

The fix is not cheap. $650+ for repaired gears alone plus a fork, maybe a drum, seals, time, maybe some bearings, maybe an input shaft repair.... you're over $1k and possibly approaching $2k. And that's with the transmission out of the bike.

Believe me, I'd rather make my money on oil changes than on expensive problems that owners shouldn't need to pay for (like stripped splines and transmission rebuilds at 50k miles).
 
I hear you.

Mack truck transmissions were pretty damn good, some of their engines, not so much.

The weigh from you is very much appreciated as you seem to share your knowledge with ease. Sometimes, that's tough to do.

I got the bike from a guy in 12 boxes with blown engine. It runs pretty good considering it isn't a diesel engine and rebuilding tranny's is one of the skills I'm pretty good at. I'm looking forward to the challenge and learning something way out of my league, so to speak. I doubt I will need a 50 ton press to remove/install gears/bearings. Then again, if I do need one, there is one in here somewhere........
