Default Ohlins settings?

Ohlins shock settings? I am also going with the 25mm cartridges .97 (.95 and 1.0) springs. Any experience is welcome advice.

I set the sag and noticed I simply weigh to much. I can get the sag numbers spot on but the suspension was just to soft over all. I did add the Ohilns shock and will be adding the fork cartridges this week. I notice while the package is nice for stock it falls short of being able to give good feed back and as said is just soft. I believe this dead feel is more in the rebound circut.

Got the cartridegs and;

I received some 25mm units ( around $1700.00 ) and noticed a few things of interest that may help someone. First is that the Cartridge tool from Motion Pro will not work with these units. Seems these need the Ohlins specific catridge tool. Also Ohlins wanted a rediculious amount for it $167.00 but I got it from my dealer at $67.00. Also you don't really need the special socket for the caps either because you only hand tighten and can use a band wrench for grip. Most current ones are rubber so no marks are left behind. The biggest thing I found to look out for is the glue on the spring preload tubes. These have a rubber bumper on each end. The glue is suppose to keep the bumpers in place. However two of the four were loose and inspection revealed the glue flakes off in some pretty big flakes. This would certainly jam in the valve and comprimise the action. These flakes were like finger nail clippings so unless that glue can be disolved somehow you have a potential point of failure. The only draw back to removing the glue is now you have to take into account the rubber caps can become miss aligned with the preload tube. Just be careful not to drop them in and you'll be ok. Just like any other catridge type fork you can use several tricks to hold the damper rod while silding the spings in ( another tool not required ). Like pulling it up and press it to the side will stop in from falling down fast and tie wire around the cap retention nut fed up through the spring are standard technics. All in all the units look nice and have spacers keep the spring buffer up and displace oil. As well as having a rubber bumper in the event severe bottoming should occur. These are pretty much industry standard things on a well built unit and go a long way to smoothing the action, keeping the oil clean and preventing damge to the valve / shim stack.

Update;

Basically the 750 forks sucked to work on. The plastic preload tube is on top of the spring and had to be notched to get to the cap retention nut. Yeah I said notched. I actually used a friggin hack saw to slice into them to make a key way for the wrench. It actually worked out very well other than the plastic shavings but that will clean up easily before reassembly. The Cartridge is some F-ed size which made me rethink just how to get it out. My Motion Pro tool is for 41,42,43mm Showas but didn't fit until I slightly bent the tabs on the end in to fit the small diameter of the Stock cart. spanner nut. I called DK who said they are unique sized and he made his own tool. So I have to thank him for being a sounding board even if he said he would have given me better price. Sorry Dan had to share the love with the local shop.
Tomorrow the Ohlins tool will be here so I can reinstall the new goodies. Baring any unforseen hangups I will hopefully carve up some WV mountains Saturday.

The rest of the write up w/pics is here http://speedzilla.com/forums/showthread.php?t=28579


So far I have the front Sag 37, Comp at 1 turn, and Reb at 15 clicks. Rear Sag 27mm, Reb 10, Lowspd -1, Highspd +2.

Think I figured out the lack of feedback. I raised the rear from 317 to 319 which raised the ride hieght considerably. Placing more front end bias thus enhancing feedback. Althought this isn't possible on the stock unit. So the whole Ohlins package is worth it to me.

Update, I have put about 2k track miles on this setup and have learned quite abit about this new chasis. Latest adjustment is raising the rear ride height to max on the Ohlins shock (I was one full turn down from max). I was having a struggle with getting the bike to finish corners when speeds were up and picking up the throttle. This wasn't an issue in the slower ride groups but really bacame a challenge when catching a tow from some fast WERA guys. I think since the weather is hot and the tracks have so much rubber down this time of year you can ride a bit harder. I also have the sag at 25mm which is less than the 27mm I was running. I wouldn't hesitate to use those setting and probably prefer them in the rain.
Worth noting is the fork settings and tire selection. Tires are Michelin races. Previous tires were Michelin 2ct's. The 25mm carts are set at 37mm sag and the rebound is 12 clicks out, comp is 1-1/2 turns. Certainly those will differ with each track slightly. I also have settled the forks from the bouncing they gave over ripples. The added front load all but elimited this. The forks are set at the taper above the triples.
