How do you know when your clutch needs to be replaced. I have adjusted it but the lever is almost all the way out when it engages. I don't feel any slipping.

 

Did you loosen the cable all the way before you adjusted the clutch basket?? Try workingHope this helps. the adjuster screw in and out to take all the free play from the rods before you make the final adjustment. Turn it in and the back it out between 1/4-1/2 turn and then re-adjust the cable out until you have 1/8" of freeplay between the cable and the clutch cable bracket.

 

Assuming the clutch assembly is stock, while you're in there to adjust the center adjusting screw, lay a short straightedge across the diaphram spring next to the aluminum index plate. The spring should be flat to .010 concave (bowed in). If it's convex (bowed out) look at the index plate and find the corresponding letter next to one of the bolts. (A, B,or C) Now remember, C is the lightest position, A is intermediate and B is the tightest. So if it's bowed out, after loosening the center adjusting screw, remove the 4 bolts and washers and index plate. Then "clock" the 4 bolts to line up with the next tightest "letter" position. Place a light drop of blue Loctite on the threads and re-install. Then adjust the screw and cable as mentioned earlier and you're all set.

Those clutches normally do engage rather late in the travel, and just because the index plate adjustment is adjusted all the way, doesn't necessarily indicate the clutches are worn out. Typically that type of setup will slip in higher dears and under load, rather than in lower gears.

I can give you specs for the discs but if the pressure plate (diaphram spring) is properly adjusted and the screw/cable has a tiny bit of free play, assume your clutches are OK so long as there is no slippage, again - that'll happen in higher gears before it'll ever slip in lower gears.
