just bought 99 headers for my 03. thanks for posting this info and the map. :thumbsup: i was already in love with my bike having just added the pc3 w/ cozy's map. can't wait now to add the headers and try yours out!! :goofy:

Thanks for the easy to understand lay out. I guess I was a bit mistaken. Having said that, it's because of the Big Bang engine that they probably came out with this for the street. My understanding of the Big Bang was the engine fired 2 cylinders within 70˚, then a long pause. I didn't realized that it was all 4 within 70˚ then a very long pause! That's why the RC30 doesn't really qualify as the big bang, but as a variation leading to it. Thanks again for shading some light! apparantly, everyone else is too. i have read 4 articles on this and they all keep saying big bang = 2 cylinders together like this: "The 'Big-Bang' Superbike engine is nothing new but, although extensively tested, it has never previously been raced due to the problems caused by the two big power pulses produced. These two 'Big-Bang' pulses, within a four-cylinder engine, create a tremendous amount of stress, often leading to failure within 30 minutes."

i had no idea this was old tech, because they talked about the fact that the v4 motogp bikes will implement this technology using feedback on the wheels to allow the ecu to know the position and vary the firing of the cylinders to maximize grip along with GPS units that will change the 'maps' in the ignition to match race track conditions....

I believe it was 18MM drain plugs from Autozone and some copper washers that worked for me. Just take one of the sensors with you and match up the threads. did this today. NAPA PART # 704-1037 18mm x 1.5 Drain Plug fits right in!

how much was the tool? please do post up ride performance. I just bought a 929 shock off ebay for $24.00 and will need to add the a stiffer spring. i dont really want to revalve it and all so i am hoping just adding a 19kg spring will do the trick.
