Sticker Placement

[Laverda120]

So in real 'pre Brexit' terms motorcycle's are cheaper now for a given capacity then in 1976/77.
There's a 'genuine' 909 mile CB250RSA on ebay at the moment going for £4,695, they were about £799 new in 1980, that's real inflation!

Great looking bike Paul. Inflation tells me that £699 is now about £5400 if that makes you feel any better.
Regarding the stickers, I have the exhaust warning on my 500 and have been told that it was only fitted to USA and Canada models and that seems to stack up with a parts list. (A and CM area codes) Anyone remember?

Or alternatively from Honda4fun parts lists:
So you takes your choice. Anyone remember?

And for the CB500: [ Guests cannot view attachments ]

My 500 had a muffler sticker, said something like "this exhaust system is designed for optimal performance, please do not attempt to modify or replace" or something along those lines. Chrome sticker on the right hand side of the swinging arm.

As 400/4s original UK bikes are much more common than CB500s it's easier too look them out. Only found one or so (out of 25) claiming original paintwork (some with low mileages) that had the exhaust sticker. They are in a vulnerable position, but all my three US imports, with high mileages still had them.
I remember the do not modify was stamped into the exhaust of some of the bikes I had in the 80/90s.

Original HM323 exhausts don't have the stamping on them like the US versions do. I found that the replacement exhausts which I think were stamped HM374 did have the stamping as they were designed to fit the CB550K which we didn't get in the UK but it seemed to be a requirement of US emission control which is why they had it.

Oh and just looked in my original 1976 UK parts book and the muffler caution mark is listed as being fitted to the UK version, there is none of the in brackets text that your picture shows, says it was fitted to all models K0, K1 and K2.
