A kindly Dubliner on Triumphrat had a copy of the owner's manual page that explains how to set the Tiger's rear suspension. A two-up loaded bike should be spring pre-load set to the highest setting (5), while the rebound damping should be set three clicks out from all the way in.
The rebound damping adjuster is at the bottom of the shock and easily accessible. Turning it in until it was snug was straight forward and the clicks are loud and easily detectable. Turning it out three clicks was an obvious process.
I took the bike for a ride today to get gas and prep for the trip. It feels firmer, less bouncy and taller than before. I'm enjoying the change.
While out and about I stopped in at Two Wheel Motorsport and picked up an Airhawk. I'd been thinking about getting one anyway after the nasty case of monkey-butt I got riding it to The Bruce last week. The gel pad I was using gets moved to the pillion seat, so everyone gets a seat upgrade.
While I was under the seat I found the height settings on it, so I moved it up one from minimum. It might quickly find its way to the top setting, but middle with the Airhawk has already relaxed my knees dramatically, just in time for a Great Lake ride-around.
