Truth, happend to me a co-rider, a board member the other day, and many other people.

so should we spring for the stainless ones???

You can work on the cylinder balance by checking vacuum levels on your thottle bodies... that should smooth out the idle. They probably leaned it out on the low side to improve the throttle response. Now that change has affected the cylinder balance at idle. Having a stock airfilter can mask such imbalances and the idle is typically bumped a bit to cover this too.

Did you remove the Pair Valve or tubes yet? Marble Mod? Small or Large Box Mod?

The slip-ons can be taken off anyways... they are useless without removing the header & midpipes. Do yourself a favor and get a Ti-Force exhaust and drop 26 pounds off that bike. Slip ons hardly ever make a gain on a Busa cause the restriction is further up the pipes.

Best of luck with your bike! AND NEVER let a Stubbs Service Writer ride your Busa!!

what is the pair valve mod, i have seen how they put the marble in the tube but what is that doing , i am new to busas, and i have a k&n filter and the tre will that aff the idle after maping?, as far as the cans i was looking for sound and not realy more power that is why i didnt get the full system, any way thanks for the input

and i still have busa gauges for sale ,

So Stubbs flashed it with the yosh box, do you know what settings they put it at? probaby +5,+5, 0. The settings will make a difference in AFR slightly but nothing you will notice on the street.

The TRE will affect the idle(in neutral) because the ECM thinks its in 5th or 6th gear as opposed to neutral so it gets different fueling. You will notice when you pull the clutch in, the idle speed will change because it goes back to the original "neutral map". Its not going to hurt anything. I ran several of them like that for years.

Also you could check the synch on the throttle bodies like Tango mentioned, some times they get a tad out of whack but not often.

The PAIR MOD is removing the pair valve and installing block off plates, OR the "Marble" mod..LOL is just stuffing the marble in the main feed hose.

The PAIR SUCKER mod, is taking the main feed hose from PAIR valve to the air box and attaching to the vent tube on the breather plate on the top of the crank case. The pair valve will then act like a vacuum pump and pull a vacuum on the crank case when running. This will give you 1-2hp on the dyno consistantly. I have tested this MANY times... BUT you must becareful when changing your oil, because when you refill the oil and start it, the PAIR is pulling vacuum on the crank case, the oil pump will have a hard time picking up oil. Just start it with the oil cap off for a few mins until the oil pump primes, then you are good to go. Then just put a vacuum cap on the air box hole that was left open.

I have MANY of these old school busa tricks if interested, PM me.
