Cruisin' Guzzisti
When I upgraded my rear suspension at about 20,000 miles to lower the (2009) bike, I also installed 105 lb/in front fork springs and modified spacers per Guzzitech, and changed out the seals and dust covers while I was there.
For 25,000 miles, the front suspension has been great. No oil seepage and good damping control, both compression and rebound.
But on a trip I took the last couple of days, I notice that the damping seems to be gone. The forks will "pogo" at least twice when you compress them and let go, the forks top out with a "Clunk" on minor bumps, and it feels wobbly in a bumpy curve.
I've had the forks apart (obviously, when I install new springs and seals) but I can't say I understand how the damping works. On my old California III, the oil in the forks had nothing to do with damping; how does it work in the Stelvio? I can take them apart to check the oil, but the male fork tubes are dry - no oil leaking, so I'm sure that the carefully-measured amount I put in is still in there?
Any ideas from experienced panel where to look?
