Use regular primary oil, Belray or Spectro works well...NO synthetics...also adjust this way rather than the way you would normally do it per service manual..it works very well, I use this method on all Big dogs....And yes, I can get you a better clutch spring that will give you at least 20% increase in spring pressure...Wish I had a chance to talk with you before now, I would have told you to buy a 12 pack rather than the 9... the 12 is less apt to slip...Adjust your clutch in these steps...
>First, loosen pushrod jam nut.
>Then loosen your clutch cable all the way.
>Now go back down to pushrod and turn clockwise till it just bottoms out with light drag (leave pushrod in this position for now)
>Go back up to your clutch cable and tighten the adjuster all the way up till you have 0 (zero) play at lever while holding back on cable near housing.
>Now go back down to the pushrod and turn counterclockwise 1/4 turn and lock jam nut down.
>Go back up to clutch lever and make sure you have 1/16"-1/8" of free play while holding back on the cable near housing.
> If you have close to 1/8", lock the cable down, and you are done with your adjustment.
