Clutch issue

[Pincushion]

Ever since I got this banshee it's had what I believe to be a clutch slippage issue. When I'm accelerating hard uphill on the sand it will sometime start to jerk violently and make some loud metal clanking noises. This only happens on hard uphills.... nowhere else.

 

I tore the clutch assembly down to have a look and everything looks great. Basket is not grooved, all plates looked in good shape (I did not mic them) and everything appears perfectly functional and the trans shifts perfectly. While apart I replaced the bushing with a pancake bearing, backed it off 1/8 turn from contact point and buttoned it up. Took it to the sand and it still has the issue.

 

It's recently come to my attention that there is an adjustment point where the clutch arm enters the case. I checked mine and the lines are 1/2" apart. The indicator on the clutch arm is about 1/2" mis-aligned toward the outside of the motor (away from the jugs). That seems like an awful lot of misadjustment. I assume this is the reason for my clutch slippage under power. Anyone think not?

 

So.... what is the protocol for adjusting the clutch? Do I start with the pancake bearing adjustment (make contact, back off 1/8 turn and tighten) and then align the marks on the adjuster arm? Or do I reverse the steps?

 

 

thanks!

Edit: Just found an online service manual and it looks as if the pancake bearing adjustment is what determines the alignment of the clutch arm notch to the case notch. Is this correct?

 

And in simple terms.... how do I adjust the clutch properly?

If your clutch is slipping you will not get any metal clanking noises. the revs will just stay high and it wont pull.

 

Metal clanking noises sound like your chain is skipping teeth on the sprocket. Check your swingarm and carrier bearings as well.
