I run the 12" 440 standard with no no clunks. 4.5 turns and Best money I spent to date on the bike.Awsome ride compared to stock air hd shocks.

Brian, I have the Standard 12 1/2" 440's and I'm 6' and 185lbs. I experienced the same results. Normally when riding solo I have it around 4-5 turns in from full counterclockwise rotation and when 2 up I go 6-7 turns in. If I don't put back to 4-5 I notice a clunk on certain bumps. Not often enough to worry about or I just got use to it. [smiley=nixweiss.gif]

I believe the "clunking" you all are hearing is the shock "topping out".

Thanks for all the input,my HD dealer told me to run the shocks at around 18 psi. I moved it back up to 30 psi and it was an improvement. I will up it to 40 psi and see what it does and leave well enough alone. I weigh 300 lbs and I reckon I'm going to get a bit of a jolt,it just seems like the tire crashes into the rim when going from one type of pavement to another. I am running air pressure at 30 front and 32 rear.

I think you identified your problem.  Your tire pressures are way low for the weight you're carrying on the bike.  My suggestion would be to try 36 front and 38 rear.  I suspect the "crashing" feeling will disappear.  I would also be going to 45-48 on the shocks or using the 440's with about 5 turns up.

I might increase the tire pressure.

I appreciate all the input, I will increase the air pressure in the tires as well as the shocks. Wish I had asked that question before I took the 8000 mile trip last summer.
