Thanks to a lot of help from the guys on this site some directly & some by trawling through previous threads i have got my shovel set up prety good, minimum head shake, runs straight & true. However at 70mph she starts to shake ( not steering head ) but side to side as if someone is shaking the sidecar from side to side, push through it to 75 & its gone but it's pretty scary comming back down any ideas.

Could just be harmonics, sloppy swing-arm bearings, or wheel balance. With a Harley/Harley car setup a steering damper is recommended.

Hi Lonnie it was listening to you tha got me to take off damper until i got it as good as i can, goin out for a run soon so will try damper again tomorrow interestingly the old girl allways vibrated at 70 but it was only a buzzing through the seat i suppose it could be being amplified by the chair frame. Hank
Hank,
my 72 hd went thru that same situation it ended up being the swing arm bearings as for a dampner I had the friction disc type.
