Hi

I picked up a 99 curvy for the wife last night, today i have changed the seat for a lowered one and also swapped the dogbones for 120mm centre to centre which advised a 45mm drop at the rear. The forks were flush with the top yoke so i have set the forks to 15mm through the yokes to the top of the fork tube not the nut.

My query is when i have taken the bike out for a test everything was fine stability turn in etc... the problem came when i tried hands off the bars, from a deceleration from 50mph the bars are shaking. I checked and set tyre pressures to 33 and 36 before setting off tyre profile looks ok had a feel of bearings while working on the front end ok, re checked all fork yoke nuts tight twice before setting off aswell.

I did try a couple of times on the way home from picking up yesterday before work done today hands off and all ok but not sure if i tried at a speed of 50 or not.

I am not sure if the forks should be even lower than the 15mm or if 15mm might be to much, just wondered if anybody had experience on correct compensation drop for the rear lowering or any other suggestions to check.

The lowering is needed as with the lower seat and lowering dogbones she can just touch the floor tiptoe.

Thanks
Nik
