[QUOTE="ET43, post: 16266, member: 62"] For a Comet with a Blacknell Bullet, 65mph is pretty good, and achieved because Peter has the correct gearing on the bike. People who know me realise I bang on about about this matter, but when you have only 28bhp, the only way to get speed is to get the gearing right, as this gentleman has done. Anything less than this gearing will make the engine work too hard. Free revs are better than slogged revs!! Peter Gerrish on the IOM in 1967 on a Comet outfit and passenger managed 85 mph on the flat and this with wicked c/r and a one and half inch carb, and that says it all. Peter, if you fit a Mk11 cam, say, a 9 to 1 c/r, a long inlet stub with at least a 32mm carb, you might, and I say might get another 5mph. Sadly, with a Comet it just ain't worth the expense, but keep riding the combo, they are great fun. Cheers, The Charioteer, aka ET43 [/QUOTE]
