Trans problem

<< < (4/6) > >>

hughes:
My 87 500 is running a Pro-X inner hub for an 89-04 model bike, that would lead me to believe that the outter hub would be the same. What parts are you looking for??

kx5tsi:
Hmm, thats funny, maybe I dont have an 87.

the pro-x hub I ordered for my bike was for the 89's-04's and it would not fit. It was the exact same hub, only it had many small splines where it slides over the shaft. My shaft has 6 big splines on it. I reassembled with only 4 bolts, since one of my posts is broken off. I know this can't be good, but possibly I could make it work with stiffer springs. I can't find a hub anywhere.

After some tinkering with the clutch cable, I have got it to grab good in all gears, except 3rd.  It shifts into third. but its just free revs. I dont think that my clutch is slipping otherwise why would it grab good in 4th? Also, not sure if it grabs in 5th, or the top of any gear. The motor was not even warmed and the plug wasn't cleared yet, it was bogging on 3/4 throttle and up. I was testing on my street and this allowed one blast down and back since I have some ornary neighbors that call the cops.

I'll get it out this week to go ride it for a while and see what happens. This is a pretty bad diagnosis since it wasn't even producing full power on my test.

any help is appreciated,

kyle

Post a picture of your bike. You could have an 86 500 or older, or the engine has been swapped out.

When you say "After some tinkering with the clutch cable, I have got it to grab good in all gears, except 3rd.  It shifts into third. but its just free revs." Do you mean free rews as in no traction at all or some traction?

kx5tsi:
I dont think its grabbing in 3rd at all., it revs like Im in neutral. Im going to try and put it up on a stand and run it through the gears to see if im getting any tire spin in 3rd.

If my clutch was going wouldn't it slip in all gears? Or is there a certain gear that it will start slipping in first? Maybe my shift fork or cogs are messed up?

I still need to get it out to an open area and get her warmed up to get a more accurate diagnosis of my problem, im not sure if the clutch is holding at the top of any gear yet since I couldn't really get on it in my neighborhood.

thanks

kyle
