| Err Throttle body size. Dunno what it is but it's still standard 748sps. Weeksy's about right on the costs involved but shopping around is always the option as different tuners add different aspects to the work as in Alan's case where he'll service the bike at the same time and you'll pay a bit less for the two combined pieces of work. I've been reliably informed that I should see reasonable gains with the work, which i'm mostly doing to maximise the use of my 54mm system, which is being somewhat wasted in the current state of tune. Yes Shazamm is right, one again that previous engine mods surrounding head work on older engines would have seen greater benefits and that current technologies allow for greater accuracy and consistency. But what it comes down to is the fact that all the bikes we ride when they come off the production line are built to a compromise, both in terms of engine tune and components. if every bike was a 996r we'd be selling our wifes and body parts to ride the things. When making substancial changes to any aspect of an engines characteristic there will be trade off's as Alan likes to say. one of these is reliabilty the other for me is rideabilty. My 54mm system would have ridden like a devil in about 2000rpm of my sps's rev range and not at all anywhere else, solution more cc's more gas. Healthy power increase. Now the knock on effect is the standard heads don't flow enough or 'efficiently' enough with the given tune and system, solution alter the cylinder head to match the demands of the system and hopefully release more ponies. We will have to wait until it's down before we can start crying or singing. I'll let you know   |
