I did have clearance issues with the exhaust pipes as there was now an extra 30mm to the shock length. I had to remove the rear footpeg and loosen the tailpipe clamp to get clearance to set the lower mount screw. A jack under the bike frame to lift the rear wheel up and just popping off the rear shocks was all that was needed. Just a note for others that may want to so something similar.

Anyway, they look good and the height is great. Much more comfortable footing for my height and weight but they are a little noisy:

Before:



After:



I haven't ridden it yet as it's late but the shocks are noisy as hell. Is this normal?

Maybe I should have greased the bushings first.

I also changed from stock shocks to longer Öhlins on my Thruxton.

Had no centre-stand and did it in the street.

The only thing I needed to lift the bike up and put the longer shocks was... A STRONG FRIEND.



Good luck!

The noise appears to be just the damping mechanism pumping the oil about, although it looks as if the springs are a bit soft or there's a 2-ton Walrus bouncing up and down on the seat...

All of my over weight walrus friends are offended. Not one of them is more that 1 and a half tons.

Moogs

Haha. Well I'm about 230 and these were supposed to have been built to my weight +30 for bags.

A very thorough and partially incomprehensible, to me, explanation but I trust em. Even though the sound is evident without "bouncing" it's much more audible than the stock shocks ever were.

Bouncing on the bike in a "garage test" creates an unrealistic, low velocity impact on the shocks. Viewing your video, it would appear that he noise you hear is the piston valving. This is caused when bouncing on the bike when the bike is not in motion, which causes the three individual compression valves in the piston to be slightly opened and the check ball controlling oil flow, which is backed with a valve spring, is barely unseated and bounces on the minute ridges created during machining of the valve seat, which then causes a chirping/honking sound. This noise will not occur when you ride the bike in real world motion. The chirping noise will also decrease over time in a "garage testing" situation as the check balls wear into the newly machined valve seats. At zero mph you may also have some sound related to the spring guide between the two springs and the body of the the shock. Again, this should not be perceptable when the bike is being ridden.

Curious to hear whether you experience any sliding toward the tank as some others have noted.

when i 170 lb bounce on my bitubos there is movement but not as much, they use progressive springs and give an excellent controlled ride, if these are indeed too softly sprung works should exchange springs, they have good stuff and are prolly more $$ than the bitubos and should work well, good luck

Moogs, what's it like to ride mate?
the long shocks will quicken the steering up heaps, might be too twitchy, suggest you fit a steering damper....

i had exact same set up with my mag wheel , went from 330mm to 365mm TEC shocks.
Now i have some 340mm hagon 2810 coming next week.

The bike wasn't twitchy at all, but i like it lower because i feel more confident with this setting.
