I understand this was the reason the bevels had quite a raked out front end to stop the wheel hitting the front cylinder - just looked it up and the 900SS had a 28° rake.
Me on my best mate's TT Panther. Last year he toured in France on it with a ride to the centenary of Autodrome de Montlhéry.
i remember a joke from my teens about Panthers with their long stroke - they fire about every lampost!
1951 Vincent Comet 'Mighty Mouse'. 500cc. "The addition of a twin lobe Marshall supercharger and an increase in the fuel mixture to 75% nitro with 25% methanol meant that the bike was now producing an estimated 125bhp at 9000rpm and returning a fuel consumption of four miles per gallon... ... won the ACU Championship outright in 1977 and the following year recorded the bikes best ever figures of 8.81/157." (For those not au fait with Drag Racing, that's a quarter mile in 8.81 seconds, crossing the line at 157mph).
This was Brian Chapman's drag bike. The single broke 10 seconds for the quarter mile, and Brian's later twin cylinder Vincent (Super Mouse) broke 9 seconds. Both fantastic achievements. Brian was actually a carpenter by trade. He invited me to visit him at his home in Waltham Abbey and he showed me his workshop with builds in progress. Lovely chap.
Another difference which I admit I did notice, and which you can just about see in the photo, is that the lower part of the header has a bracket welded to it which was bolted to the frame down tube. But apart from that there was nothing holding it tight into the head
That reminds me of a Norton 16h. I almost bought one a few years ago, it was a daily rider for the owner and in oily rag condition (which I like). He didn’t want much for it either but I hesitated and it was sold
Aha! I see - screw in stubs, push fit spigots, screw in clamps or finned clamps and flared or straight pipes.... sheesh there's more than enough there for a substantial entry into the Dull Men's Club library And true about rarely accessed memories - many years ago I could read ISUP messages in their raw hex format. But only because I was looking at them for pretty much the whole day every day. I'd have trouble with just the hex conversions now... Anyhoo in keeping with random photos here some screw in stubs & push fit spigots...
I recently sold a T120 splayed head with screw in exhaust stubs,I have always called them stubs,but don't know where I obtained the term.I do remember the 'Stubs' had a tendencey to unscrew no matter how tight you did the finned clamps.
My T140V (screw-in) stubs are as per the first picture. The head also has 5/16-threaded grub-screw holes for added security (that I don't use). I think it was a really daft idea to have push-in stubs on the Triumph twins as they'd surely vibrate and damage the heads so they became a piss-poor fit. Hence the screw-in stubs... Non-old-Brit-bike owners can now wake from their boredom slumber...
