Trying to adjust the preload mechanically but the little pin to the left of the hydraulic preload hose where it enters the shock collar prevents the rings from spinning so you can't adjust the preload. Anyone worked on these and know how to move that pin out of the way? There is no mention of it in the instruction booklet.

I was just talking to Mark @ Computrack about that very thing last week. I was going to get an Ohlins for the remote preload adjustment and he told me the range of adjustment is pretty small then you have to dis-assemble the shock to get further adjustments.
He also said Penske was very easy to manually change the preload...is that correct Travis?
At any rate give him a call and I'm sure he can talk you through the procedure...

Did he mention any specifics to you? The shock has been sprung for my wieght so it may not need any more preload, I won't know 'til I measure the sag tomorrow. I got the 4-1-1 from Chuck Graves himself on some rebound and compression settings. I just wanted to know how to handle this. The Ohlins I had on my 12R didn't have that little pin. I was always playing with the suspension on it.

I have a Penske (not by choice) on the R6 and you simply rotate the ring above the collar. However, be careful because they do have a little screw that tightens on the ring to hold it secure at the setting you wish. Some forget it's there and just strip it when they rotate the ring before loosening that little screw. FYI.

Yes, there are holes in the collar where you insert a rod that has a ~30 degree bend on one end, just turn it like a wrench. It doesn't take much pressure at all. There is no defined limit to how much/little preload you can have. By the way it is possible to get a remote preload adjuster for Penskes. It does have some limits and its exprensive.

Okay GMD had the answer I was looking for. I was surprised so many people didn't know the answer. I posted on a CCS website as well and called fellow riders/racers. Apparently on Ohlins shocks with the remote hyrdraulic preload, if you want to adjust the preload mechanically you must remove the shock from the bike, remove the spring to remove that pin and then use a spanner to loosen the ajustment rings.

According to GMD the hydraulic preload is more effective than I thought and it has a good range of preload adjustment. They said it will give you a range of about 15mm in sag which is pretty good. Getting it sprung for your weight is very important and they are counting on that, thus the hydraulic preload. So it is easier and quicker to adjust preload. I was told a while back by someone that the remote preload was useless. So much for that advice.
Okay, I feel better now.

Glad you found the answer. Did you talk to Mark? He seems to know his stuff...
Thanks for the Penske info. I'll see what kind of deals I can find at Daytona...
