Demort said:Sounds like your on the right track ..
I had a little list id thought of as to what it could be ..
Rear wheel balence .. might have a missing weight and with the hard mounts you have might cause it , this would be speed related though .
A/C pipes were they mount , its a rubber block in a plastic houseing , if the houseing has twisted you would have the pipes touching the plastic houseing which might cause it as these are new.
Gearbox mounts.
To find it i would use something called a chassis ear .. ill let you research that one
Thanks Iain I will find out what one of those is , I will also go through your list with him . thanks for the suggestions mate. :thumb: :thumb: Are you going to make Beaulieu this year , I want to buy you a coffee and introduce you to the AiB girls :floor: :floor: :floor:
