When adding emulators the directions say that there is one existing hole 48mm from the bottom and to add another. The weird thing is there appears to have been an additional hole drilled, and then soldered back up on my rod. Also, I have 4 holes drilled on the bottom near the compression valve. From looking at pictures on parts catalog it seems there should only be 2? Was stock 2 or 4 at the bottom?

I'm going to get the Racetech Emulators installed today. Try to test ride it Wednesday and race at Mid Ohio Sunday. You should make the drive up and check out Mid Ohio Vintage Days.

With Emulators it doesn't matter if you have too many holes for compression. You need a free flow of oil to reach the Emulator on compression.

The objective is to have enough flow through them that they don't influence compression damping at all and instead the emulator takes over the job.

The only holes in the damper rod that are still working are the rebound holes.

The emulator handles all the compression responsibility.

Madmax31, I am assuming that someone"revalved" those forks. Welding up a stock hole and drilling another smaller hole was something that was used to "revalve" the forks.

Almost, but not all, compression is handled by the emulators.

Good luck at the race!

Short ride report. I installed spring rates for me via Racetech and added the emulators and a Simon link. A vast improvement over what was on there. The suspension definitely reacted more like a modern bike. Can't wait to get some more time on it and actually adjust it a little. Most of my time was spent adjusting brakes and changing jetting.
