Polishing up on my suspension know how
 
1 Attachment(s)
Prepping the damper rods by disassembling the rebound stacks, dressing the threads, and 5 element polishing of the tubes outer surface, the bottom one is done the top one awaits my attention... All this in preparation for a trip to see my pal Mike Weber (Ducati tuner extraordinaire) for shim stack assembly. While I am fully capable of building these out myself, Mike will show me his tricks all the while giving me the knowledge of all the science of how and why shim stacks work... That is priceless!

Would be great to hear what your final setup is. I've changed out the fork parts in all three of my Hondas, generally using Racetech or Daugherty parts, and have tried a number of variations of shim stacks.

Currently using a Racetech C32 and Rh16 pattern in the VTR with 0.85 spring, using a Showa 3-port compression valve and Gold Valve for rebound. Similar but with 0.9 springs, Daugherty compression valve and rebound Gold Valve in my VFR (using CBR600F4i forks, but the internals are all the same size). My ST1100 is a work in progress with 0.9 springs, Daugherty compression valve C32 shims and the OEM rebound valve with Rh17 shims.

I'll let you know where I end up originally I was going to use the racetech .90 springs but after talking with Mike he felt that it would be slightly oversprung for the stree so I am shifting to .85's both rebound and comp valves are racetech stacks are t decided on as of yet

Cadbury,
Racetech recommended.90 springs, with a C35 compression stack and a rH 16 rebound stack, we will see what Mr Weber comes up with!

To clarify for me, does "5 element" mean you're using 5 different compounds to achieve the final finish?

Yes, starting with 1000, then 1500, then 2000 grit wet and dry lubricated by light macine oil. Followed by Rollite coarse prepolish, then Rollite metal polish. Decontaimnatsd with rubbing alcohol... Smooth and slippery

We ended up with the C35 stack and a restrictor of 00.09 and a rebound of rH16 and a .85 kg/mm spring, 5wt oil. I'll try and remember to post how I like it next spring

Thanks Fastguy; what do you mean by the restrictor?
