I had soft long travel on the old shock of My G/S. It was a Koni with the oil on the outside.

Got the spring from HH today- included are a couple of extra spacers, two nylon 35mm longer spacers (25mm AL ones were supplied w/ original order) to be tried with the 4.8 springs and 5.8 springs along with a 20mm spacer. What has me a little confused is the 5.8 spring has the 20mm spacer attached via a wire, and the spring is the same length as the 4.8 spring.

Here's the measurements of the 5.8 spring.

Brand..................Kg/mm.................. OAL............... OD............. ID........... Wire diameter......
HH Race Tech..........4.8................... 451mm...........32.86...........24.10............. 4.40...............
HH Race Tech..........5.8....................451mm........ ..32.97...........23.05..............4.60......... ......


SAG Measuremens- R80G/S, rider 74kg, 5wt fork oil

Brand..................Kg/mm..................# of rings.....Spacer ........SAG laden.........Petrol...........Comp / RB
HH Race Tech....... 4.8.........................4...........25mm..............66mm..............20L.............+1 .5/+1.5
HH Race Tech........4.8.........................2......... ..35mm..........+/-56mm..............12L.............+1.5/+1.5
HH Race Tech........4.8.........................3......... ..35mm..........53-55.1mm...........12L.............+1.5/+1.5
HH Race Tech....... 4.8.........................4...........35mm..........+/-54mm..............12L.............+1.5/+1.5
HH Race Tech....... 4.8.........................5...........35mm..........+/-56.8mm............12L............+1.5/+1.5

HH Race Tech........5.8....................

Note- I had some major variations on SAG measurements for the latest measurements w/ the 35mm spacer.






Looks like I've got some spacers and springs to mess around with for a while.

Preload on the fork springs is not a lot more than the depth of the thread on the cap, and preload on the shock as supplied by Ohlins at 18mm.

With this setting I need very little compression damping and a bit more rebound than the recommended mid point, but this depends on the tracks I am riding, and is adjusted on the move to suit.

You also need to adjust it to match the damping on the Ohlins, which changes as the fluid, etc, deteriorates with use, and the deterioration is quite noticeable when you are close to optimum with your settings.
How is Ohlins shock oil suppose to deteriorate? Other than water and dirt getting in?

Perhaps BB means the fork oil deteriorating?

Ohlins recommends that you have the shock serviced at 20,000 km intervals, and that includes a fluid change.

And with a quality, well set up shock you notice the decline, from just serviced out to service time.

But with the WP on my G/S matched to the stock forks it doesnt make much difference, it didnt change much in 70,000 km and servicing it didnt make much of a improvement - a second rate set up just stays second rate, as SS has confirmed.

Any oil degrades in use, fork and shock, but the shock fluid seems to go quicker than the full synthetic 7 1/2 wt HVI suspension fluid I use in the forks, probably due to the closer tolerances in the shock.

Fork oil doesn't degrade in so much as it gets contaminated. There is very little shearing and the heat isn't that much. What is wearing out in those Ohlins besides needing to recharge the gas? Bushings? Having to rebuild your street bike shock every 12k miles is unacceptable to me. I picked Fox when I got a shock for my Mono for all the oil leaks and trouble I have seen with Ohlins. Hopefully it isn't the shock body wearing out?

Of course they would spec a short service interval, to cover ass, much like the 70 hour bottom end replacement spec on the G450X and the minute you take it (the fluid) out of the shock to do anything, you would be silly to put it back in.

That part of the story I can understand. It's the rest of it that I can't figure and since that is the whole reason for going into it in the first place it's not the answer I was looking for.

Took the bike out for a short ride due to a kick ass thunder storm coming in...yeah I know. But anyway used only 150mm of fork travel on the ride. After riding w/ the 4.8 spring today I'm thinking the 5.8 will be too stiff. I'll still give it a go at a later date, but still want to fiddle with the 4.8 spring.

Running the 4.8 spring and 35mm spacer seems more acceptable to me. But dang I wish I knew what I was doing on the comp and rebound adjustments. My butt gauge just isn't that sensitive. It may just take A LOT of fiddling for me.

Run em all the way in, and then all the way out a few times over the same piece of uneven ground. YOu'll feel a difference, I think. I agree, the .48's are a pretty good size spring. Doesnt pay to overthink it.

The rougher the road the easier it is to tell what is wrong - I farted and fiddled around with the road set up my VFR , getting nowhere, but one run down a potholed and corrugated dirt track and I new what I needed.

Apart from clean underpants, that is.

One Canadian inmate has his cartridges sitting at customs in Toronto. He needs to pay the duty and pick them up. I haven't got time to look up who it is, but I would appreciate if this was done promptly. I guess they would be sent back to Racetech, if this is not done asap.

Customs and Duty all paid, now.

Strangely enough my shipment is doing the final 3500km of its 8000km journey by FedEx Ground ????

Any more reports on the inserts ???
