i have a whole set of fairings I slowly picked up from ebay.
All were damaged but easily repaired.
I have 2 tail sections and paid less than £15 each. each side cost 20 to 25.
and top section 30.
The above top cowl was vertually broken in half, but plastex and a soldering iron soon cured that.
If you have a lot of time and patience oe bits can be picked up for sensible prices,if you can wait.
headlights and tanks are always a struggle mind.
Decals cost me 150 quid fitted to my white Sp1 from the Image works.
Its the spraying that will cost you ,unless you know somebody.
