Any of the shock oils out there should be good, I am starting to research this now. The weight of the oil is important.

 

i did the race tech springs and gold mod, and adj to lower one inch, wow what a diff, and i used race tech oil, very spendy but what the hell i think 35 a quart, but haveing a wideglide (05) it made it so much nicer no more shimmy at high speeds and i can keep up with any sporty in the twistys

 

I'm installing the Ohlins Drop-in cartridges this winter on my Dyna. If anyone is interested in my Racetech cartridge emulators, pm me. Jay Risk
