new to the forum so hello to all, u guys should like this. I own a 97 900rr that is missing 2nd gear, instead of fixing 2nd gear I went and bought a 2007 special edition zx10r(removed the flames that day)but to my dismay I find myself really missing the raw power of my 900(whoda thunk it).So my question to all is can I attempt to tackle this myself or is this something I should have professionaly done. also what am i going to be spending whether on my own or at a shop.thanks for any info

Some people will recommend just changing the shift forks but this will prove to be a temporary fix at best. Depending on how worn your gears are, it may not work at all. You will need to change them but also 2nd and fourth gear as well. The gears lock into each other with these little tabs, I've always called them "dogs" but I'm not sure if that's correct. Once a shift fork bends the dogs don't lock into their corresponding holes in the next gear as positively as they should. This results in the edges of the dogs and the holes being rounded off (it can be very slight but still cause a problem) so new shift forks alone isn't going to cure it permanantly. To fix it right you're looking at about $200 total in parts without a discount. It's not a real tough job, just be careful during disassembly.

If you're handy with tools you can pull the engine, fix the tranny reinstall the engine and be riding the bike the same day, provided you already have all of the necessary parts but I would wait until you have it apart to order the parts so you can be sure you're getting everything you need.

I was reading something like this on another site and they say it can be easier to just buy an entire new engine, rather than take apart the old engine to get at the shifting stuff.

Very expensive if you pay someone for parts alone and add labor and it's really pricey.

dosent really matter which bike. if your not to handy with a wrench you might be better off with a swat. the swap is only half as hard but then again you have to be sure the engine that your swapping in is in good shape

I'll second that. A swap would certainly be the way to go if you found a good used engine. You could pick up a used engine for $500-800 and have it in the bike in about 4 hours. Plus, you could probably sell your repairable motor for a few hundred to offset your cost. But be careful on the used engine... It really sucks to do all of that work only to find out you bought an engine with a rod knocking. I've been there.

I have a used Trans, has 10k on it. Everything is well withen spec gears shafts bearings very nice, id be willing to get rid of it cheap. If you dont wanna get to much into it just get shift drum and the shift forks, 2nd gear shift fork is known to go out on these bikes, i had the same problem with mine saw that the shift fork was worked down to a nub, about 200 bucks in new parts. i would try this first before doing anything else, changing the trans requires spliting the cases and thats a bitch! is it going into second gear at all? or does it go in and slip out at a certain RPM??

I can shift into 2nd but as soon as i give it anything she slips back into neutral.I first discovered this while attempting to pass someone(not so fun)at that point i could cruise in 2nd just not heavily accelerate but it has gotten progressivly worse. if you think a new tranny would be the best bet i'd gladly take that but let me know

telling you bud the same thing happened to my bike. i started to tear her down but the owner of the shop i was working at (owned shop 20 plus years) told me i was crazy and to just swap it out. so i did and a day later was back on the road.

no, you dont need the tarnny. I would follow the procedure in the manual, I.E take off clutch and its inners, drop oil pan, inspec the shift drum and replace the shift fork, all the way on the left! i bet its ground up at the Dog! just make sure you check the groves in your shift drum too Because if you dont and its a bad grove youll be in the same situation in a few hundred miles from now. if you have any questions thiers alot of guys on here including me who have taken every nut and bolt off this bike, just ask.

Thier isnt a nut on this bike i havent turned. I work As a engineer and do side projects [performance car] and Bikes. I also got my bike off a guy who stunted his CBR so i had plenty of proplems.

So if my bike likes to stop in neutral before going to second (pretty much always takes two good upshifts) am I screwed pretty soon?

"JEFF1980" is right. just changing the forks is a temp. fix. upon inspection, you'll see the dogs are rounded. if they're still with-in spec, you can undercut them.

putting a used motor is only asking for problems. fix it right, and you'll probably never have to do it again.
