[QUOTE="macvette, post: 109527, member: 262"] My bike came with a new repro silencer which I fitted during the rebuild. It's a D like Gary's. After running in, it struggled on accerarion from 80 mph and up. After many carb and ignition resets it was still the same. I had read about the tests on the original spiral baffle silencers ( the repro is spiral baffle) so when the Spares Co made their repro, I got one. It had a significantly larger central pipe than the one I had fitted originally, was louder but not signficantly so. That cured the reluctance to pull strongly from 80 upwards. At the same time I replaced the kickstarter shaft with a longer one which gave more clearance from the exhaust. The bike has a C cowl and I managed to fit the exhaust system with clearance (albeit not much) all round. I'll post some clearance pics, sorry they are not brilliant, it was dificult to get my phone in good positions. [/QUOTE]
