Considering a new chrome cover is the best part of £60 the CMS price is quite reasonable. Even NOS ones can show some damage, mainly to the lacquer finish. I polished mine.

Yes, Ken put me onto them.
Can't remember, I might have used longer fitting screws
Plus a gasket as the round ring has no recess.

Different bolts needed. Use the 8mm headed bolts Honda used on the 650 is my advice. Don’t think Honda used a gasket on the 650 but the cork one out of the chrome cover should fit if you feel the need to fit one.

Thanks to Dave Engine Bars   - all Fitted

I took care to make sure the bolts did not touch the engine casing by filing 2 mm off both bolt and also nut so there is still a gap to casings

They will look better when out and about on pics

here is a few from in the garage

The bolts are not a problem when fitting thecbars, its if you use them after taking the bars off because they are longer

Not really looked at the design before, they look neat.

The ones on my Superdream were not shaped & sculptured like those.

I didn't realise that design was still available, I had similar on my 1972 750

I was lucky enough as Dave had a set he bought in 2017 i think and didn't use them they were still boxed up
Just shows how forum members do help each other out.
