Thruxton Rear Preload Adjustment

I set the front to two lines and when I went to tighten the rear, there is just a hole with no screw or anything to turn. Help please.

it's a stepped preload..I think there are 4 or 5 notches, you stick a spanner (or old phillips head in my case) in the hole and raise or lower the position the notch lies in.

You mean literally just stick a screwdriver in the hole and then lift up the collar it is attached too?

A screwdriver will work on the non drive side but it is tighter on the drive side. I use an allen wrench. Just put the small end in the hole & turn it. Can't remember off hand the settings but it is in your manual.

by "turn" they mean grab and twist like a mother.

I stick a big allen wrench in there and yank that sucka.

Yeah, you want to physically turn the collar to the desired position, the screwdriver just provides the torque to do it.

i actually found it easier with someone sitting on the bike to do it

seriously????

that makes no sense..adding load to the spring would seemingly make it harder to turn..in fact, I have my son (6' 4", 275 lbs) pick up the back of my thrux when I want to turn the collar. I'm then able to do it by hand..
