350F exhausts from CMS, DSS & AC-Motorradteile (Germany)
JamesH:
Roy keep going mate, these things have a habit of turning round...I sourced mine from Germany (Andy Cepok) - may be worth dropping him a line to see what he still has in stock? Obviously explain the quality issues you've had with DSS and CMSNL....
AshimotoK0:
It's a real pity that Yamiya don't extend the range they do. They are not even planning to remake 400/4 pipes but they must have good manufacturing contacts, possibly with the OEM suppliers to Honda (Sankei etc. ). Anyone remember how long ago it is since Honda discontinued supply of 400/4 exhausts? What I did with my CB250K0 was source a pair of NOS Genuine Honda pipes and THEN buy a bike to restore.
BTW Roy ... my 'man' is on with analyzing the rubber from the aftermarket F2 carb rubbers and says he will have an answer tomorrow for us, after I chased him up on it.
Will post this in the correct thread but he says it may be beneficial to post cure the softened ones in an oven at the maximum temperature they would see in service? Can anyone suggest a temperature or in a position to measure it on a hot engine?

Cheers Ash. That's maybe why they went softer on the engine side after a few heat cycles?

I am glad i hoarded when i did, i have a NOS F2 exhaust, and NOS F2 carb rubbers, i wonder what they would fetch on fleabay
The 350 pipes sound like a nightmare, as demand becomes high for these rare parts amater firms are supplying the market with bad quality, i would have thought DS and CMS had stricter checks before they stock these parts, the for stanchions ds sells for the 750 KO are not much cop neither as you have to do machining to make them fit

I think they must have had a bad batch as if you look on the DSS USA site they are also offering factory seconds at a reduced price, these are not listed on the UK site.
Just about to order a set from DSS UK and i hope they are not like you received, which i suspect are the factory seconds.
