Mod the airbox at all?

on modern watercooled bikes, this isn't true anymore unless you're running low on coolant.

You didn't mention what bike it is, but if it uses wasted spark ignition, the most obvious connection between 2 and 3 is they are both ran by one coil. Might have a wire, boot or plug causing both to have weak spark. Wasted spark systems use the second plug/cap/wire as the return path, so an issue with either cylinder will effect the other cylinder.

i'd like to jump in on the bike v car debate with deals and slowpoke.

i posted a while back about an article in Australia in both a bike and car magazine that pitted a $300,000 Porsche with ceramic brake upgrade (worth 20k) versus a GSXR1000 (K4 worth 20K)

the driver was a well respected race driver down here and the rider was just a journo for the bike mag. they "raced" around all day doing time trials and finally against each other.

outcome: the bike only won by being quicker to accelerate out of corners and carried slower times and speed through the corners which only allowed for a very small win.

this test was then televised as an addition to our sunday car racing.

Well weather or not it will beat a Busa depends on the driver. I have an 05 Hayabusa and with the new clutch set up it is very hard to launch. I have seen times on the new bike and speeds of only 141mph. Thats not good enough to beat a busa or even a ZX10r for that matter. Second with the aftermarket for the busa you cant go wrong with a busa. If you want 500hp all you have to do is pick up a phone and a wrench.

That being said I hate my busa. It is great for a straight line, and for a 500pound bike it turns pretty darn well. I had my ZX6r stolen and they gave me enough money to buy a new busa for cash, so I did. I regret it everyday I get on the damn thing. The sad thing is its starting to grow on me. It turns like a semi truck. One of my favorite things to do is get on the interstate at 4am in the morning and try taking the circle entrance ramps at higher and higher speeds. My busa is moaning and groaning at 60mph where my ZX6r would gladly take them at well over 100mph. Sure I have fun taking the busa to the drag strip, but I miss the everyday driving of the smaller bike. If you want a fast bike just get a busa, add a turbo for about $2000 and a day of work and change the clutch and you will have a bike that is as fast as you will ever want it. I am sure they will come out with turbos for the ZX14r but it will be years before you can get one for $2000. Second have a 600 or 1000 for driving on the street. It sucks having to carry that 500 pounds around with you every where you go.

Oh yeah and unless you can really drive and you have changed the clutch out to get you off the line better a ZX10r will smoke your busa everytime. Why they put a friggin racing clutch on a busa I will never know. It is a drag bike. I assume the ZX14 has the same clutch problems as the busa too, as the best 60ft times I have seen are 1.83 seconds. My SRT4 with slicks runs a 1.6 60ft. Hell its embarrising to get beat off the line by a friggin 4 door neon based car.
