I've a recently acquired 1970 175HS. While I've restored a number of bikes over the years, and built 3 Cafe Racers, this is both my first Bridgestone and first 2-stroke project. I'll probably need to candle the minds of the membership for a variety of things, but an early one that came up was the connector between the header pipes and mufflers. My bike came with some kind of what appears to be radiator hose held on with hose clamps. This is obviously not stock since the Parts Catalog has a part # for the muffler joint rubber. So, my question is, is this "modification" (what's the British idiom, bodged?) what is typically done and acceptable? Why? Because the stock joint rubber is unobtainable, or doesn't work, or too expensive, or? Or is it preferable to use the stock joint rubber because Richard has a warehouse full of 'em?

Richard usually has them listed on eBay. The radiator hose seems to be a standard "make due" solution although I'm not sure they hold up for long. I bought 2 bikes that had a chunk of radiator hose and hose clamps in place of the standard piece.

Any ideas on better clamps then those little wire clamps for this union between the two pipes?
I have been looking for a thin hose clamp of that diameter and have not had any luck. I get some gunk coming out of that rubber even though I have new rubber.

I haven't tried this, but it could help, they would provide more tension than the BS parts. They're available in 1/8" increments. You may be able to find the right size locally.

you could probably get some clamps for pod filters that would fit
