There is an excellent Indian video (which I can’t now find) where a fellow rides his 450 to have the seat sculpted. Out comes the sculptor from the shed, a few tools and bare feet to do it at the roadside, sat on the pavement.
Here in the UK?
Enquire (often without a ‘please’ or ‘thank you’) on UKGSer as to who sculpts seats, price, address, email, colour of front door, shoe size etc etc etc
Pay (begrudgingly)
Post away (while moaning about the cost)
Wait around for several weeks (more moaning)
Maybe get it back
….. and it’s us that’s the first world country?
