Lever Shocks

[oconnor@Fuse.net]

This winter I'd like to upgrade the lever shocks on my TR6, an IRS 
Triumph.  Has anyone on the list modified theirs the way I've read 
about how J.K. Jackson at EAS does?  

Apparently this upgrade involves a .070" washer placed under the valve 
spring, and 30 wt. oil in the shock.  Anyone ever done this?  Do I 
need an "adjustable valve" or is the stock valve an adjustable valve.

Thanks for any info.  
Sincerely,
Kevin D. O'Connor
