[QUOTE="ET43, post: 16273, member: 62"] Hi Norman, I agree with the figures in the rider's handbook, but, they do not allow for a ferkin great sidecar being bolted on to the side of the machine. The Blacknell Bullet is perhaps the largest single seater around, and probably the heaviest too, so the combined weight is likely to be around 640lbs, add to that an extra 4 square feet of frontal area and you are not going to go anywhere quickly. I have ridden around ten Comet outfits and none of them came close to 65mph, except Dick Sherwin's which had 8-1cr, Mk11 cam, a 56t rws I think, and that did 60mph. Even riding the plot down a steep hill will not advance the speed overly much due to the frontal area. So, if Peter gets 65mph from his machine, then to my mind it is in good order. Going on a bit further, Steib recommend not having a screen and a tonnaeu cover on together if no passenger is carried. Why, because of the drag of the screen! Why have one up if there is no passenger in the sidecar, that is unless you are a high street poser. Wind, and I do not mean the Baked Bean variety, is a killer! Cheers ET43 [/QUOTE]
