What causes a trans to slip?

I am looking at getting a 96 Katana but the owner says the trans is slipping. For one, what does that mean? Two, what causes it? Three is this an easy or somewhat cheap to get repaired?

Thanks in advance.

Trans slipping could be as simple as it needs a new clutch- or it could be that someone abused the bike to the point that the gears in the trans are worn/broken... Price to replace- ? I don't know. If the bikes in good shape and the price is right- see if he'll get some quotes from a local shop for repair costs.

The ike is a 96 with 3200 miles. He said he thinks it is gears but he doesn't seem to be mechanically talented to really know. He said he thought 300 to rebuild the trans but that sound too cheap to me.

Without more info, we can't help. 3200 miles on a Kat is nothing, unless the bike has been wrecked or abused.

You NEED to find out what he means by "slipping"; does the bike run and shift OK, but the clutch slips on acceleration (revs rise but the bike doesn't go any faster) or does the bike POP out of gear or not shift properly (false neutrals) when shifted and power is applied.

The first is caused by poor clutch ajustement ( $0 ), or a fried clutch (a couple hundred bucks);

The latter can be caused by a. Stuck shift detent mechanism ($100 or so) b. bent shift forks (couple hundred) c. damaged gears or dogs (many hundreds, depending on if busted parts have been floating around doing other damage.)

If the bike shifts poorly (stiffly) because the clutch is dragging (and with that few miles, it has sat a LOT and may be munged up), it may be simply a case of sit-itus,; fixed with an oil change and a little riding.

YOU NEED MORE INFO>>>>>

If the bike only has 3200 miles then it's probably worth fixing. But yeah more info. What does he want for it as is?

NADA shows 1600 but thats with a good tranny: http://www.nadaguides.com/default.as...S&gc=MC&gtc=MC

so if you can get it fixed for 3 bills- it looks like a good deal. Keep in mind if its been sitting for 6 yrs its gonna most likely need a few more things. like fuel system flush- possibly new fuel lines- tires - battery - ect.

Offer him $1k... Remind him of his costs associated with storing it...

Something doesn't sound right with thies numbers.

"Slipping trans" by definition in the clutches slipping in an automatic trans. Manual trans. don't slip. They are gears connected to gears. Somthing is probably wrong with it or it has a fried clutch and he is an idiot. Have the bike checked out by a tech if you can.

with 1SP. 1k is worth building a bike.

With more details I or someone else might be able to help.

with 3200 miles on it, I'd get it checked out. either its been abused or something is out of adjustment. if you can get it for cheap, by all means go for it, and build up a nice bike from it.

He said the trans would pop out of gear and sometimes lock up. I passed.

Thanks!

A SMART decision; sounds like busted gear or dog....and the pieces are floating around.

I agree! LOL

good move. its been abused quite a bit, I wouldnt even have paid more than $500 for it and spent the grand left over in rebuilding it.
