The 1100 Sport is a great bike, but it hardly is maxed out from the factory in top tune. Yet somehow, that 1064 2 valver with Dellortos would run neck and neck with a Daytona 4V at top speed, dyno fiqures be damned.
Seems we are in an era where innovation and hot rodding are discouraged , and dumping our ride for something with more power is the preferred intelligent method over hands on hot rodding. Argue for limitations, and they are yours.
A brief look at what else is available in the market trying to get more out of something like an 1100 sport is an exercise of rolling a turd in glitter and this is what Pete and a few others are trying to point out, if you are expecting another 10hp out of an exhaust swap like you got on your vaguely recent sports bike you will be miserably disappointed . Providing the people undertaking the exercise understand it is rolling a turd in glitter and quickly becomes and exercise in ever reducing gains I don't think anyone has a serious issue, something about managing expectations.
Pretty much the 1100 sport motor is maxed out, well as far as the factory who needed to pass emissions and provide warrantee was prepared to go, sure you get some mid range gains if you dump the archaic delortos and a little out of the exhaust. The 1100 sport had to pass 25 year ago emissions not current ones so there is not a lot of gain in basic tuning compared to what can be had out of a modern stock bike. We then start talking about machine work and re-engineering, which gets expensive fast for little gain assuming you can find a machinist that is prepared to mess with old munt and how much of the motorcycle vs nail bomb trade off you are prepared to accept.
In a straight line the vaguely stock (stock they were an almost unrideable tuning mess so not many are actually stock) 1100 sport will run out of gearing and rpm at about the same time an A kit daytona and only the A kit will run out of grunt and aerodynamics, I seriously doubt the 1100 sport can pull any taller gearing. The C Kit motors as fitted to the Racing and RS will piss all over it, a well set up Ducati 1000DS (two valve aircooled motor) will also have it for breakfast. First gen Aprilia Millie's/Falco's as also on a whole another league. Modern bikes are engineered to an incredible level i.e the R1's frame is of varying thicknesses to allow for flex and stiffness to optimize handling this has been the case for at least the last 10 years maybe you should go take one for a run.
