Its impossible to fit it incorrectly, its just fastened with 2 bolts through the webbing and 2 small plates at the top. Theres just a large cable tie securing the harness the the frame at the bottom.
I'm in North Lincolnshire, on the East Coast...about 3 hours from you in Hertfordshire.
The only thing I can think of that would make this hang further back that the PAP is that the tuned exhaust is bl**dy heavy. As the Solo 210 engine is quite large front to back, this means that the heavy exhaust quite a long way back from the hang points, so needs even more weight in front of the hang point to counter balance it, given that the hang point is actually in front of the center of balance
Does that make any sense?
