Sorry man. I got nothing for you off the top of my head if you checked that stuff and it all seems fine. Are you shifting it with authority? I can only assume that you are. On occasion if I would shift to 2nd doing wheelies I wouldnt get it in all the way and it would pop back out into Nuetral. That is all i can add man. Good luck. Something is obviously MIA in there.

Could it be an external linkage problem? maybe something is blocking the linkage or hitting against it, or maybe the adjustment is different for the 99 motor. I have a 99 900RR and I've always thought the shifting was a bit notchy, but it's never done that.

The 900rr was notorious for trans troubles in 2nd gear. My 94' had the same problem, the solution is to either replace the worn "ears" on the gear by undercutting the trans or by replacing the gear itself. It will not get better on its own and there is NO adjustment to make it better either.[:@] sorry man[>:]

Well i think James said it best sorry about the bad news guy. Well here is some good news, if you buy a manual and find a budy with some mechanical knowledge you can fix this problem in the garage in about 6 or 7 hours + a couple of 100 in parts. My friend just did the same thing to his black bird and it runs like a new bike now.

Couldn't he just transplant the trans out of his old motor??? Or was that destroyed when your motor went out??? Just a thought...

That would be my thought just take the 2 trannies and make a good one may take some time but it won't cost anything since you already have one. my suggestion would be to take the one out of the bad motor first that way you can use it as a learning experience. +1 batman911

I had a problem with 2nd gear on my 95 and I took it to the honda dealer and it cost around 2500 bucks. They changed the shift forks and 2nd 4th and 5th gears, so if you can do it at home I would at least try it and save alot of money.
