gear slippage
Hi, I have a 2000f4 with 14k miles on it. On two occasions the other night when trying to pop a wheelie, I would be moving at about 7500 rpm in 1st gear and then give her some clutch and rev it up. All of-a-sudden it would rev up to redline and go into neutral. You have no idea how embarrassing this is and how much it pisses me off. I know its some sort of tranny issue. I change the oil every 2500-3000, and the previous owner changed it every 1000.
My last oil change (about 1800 miles ago) I switched from regular Honda dino oil to the Honda semi-synthetic 10w-40(without molly). I also notice when shifting in lower gears and mid rpm's, the tranny makes a clunky sound when it shifts and I feel a little feed back through my shifter. Has anyone else experienced this problem? And if so how much $$ am I looking at to fix it. I would really appreciate any help.

RE: gear slippage
you have the case of a bent shift fork problem. It could also be a fork shaft as well. Typical indications are slipping out of gear/clunky noise when shifting. This is HIGHLY common when doing wheelies and missing a couple of gears here and there. I fixed this myself on my 954 and it cost me $40 for a shift fork. I am experienced in engine overhaul so it wasn't a problem for me. But if you aren't be prepared to shell out some money for mostly labor costs. I called 3 shops before i fixed mine and the cost ranged from $1,000-1,500 to fix.

RE: gear slippage
no you can get to them by taking off the oil pan and getting them through the bottom. Thats how i did it on the 954 engine but i'm not sure about yours. You need to get a maintenance manual. You can find cd-rom manuals on ebay for around 5 bucks. Also here is a good site to get parts. www.bikebandit.com

Ya, according to the manuel you have to take the engine out. Im not sure i trust my self to take it out and put it back together. Maybe I should just sell the bike...

I'd have it checked out by a shop before making any major decisions
