Busa Feeling SLOWER?!?

[johncal]

The reason it feels slower is because the engine has been tuned up. If you have actually gotten the proper 600 mile service, you will have not only had oil changed, etc. but you will have also gotten the throttle bodies synchronized and you will have had the throttle position sensor adjusted and fast and slow idle adjusted.

All of these things being done will have your bike working much smoother. The off idle surge will be lessened. This makes the bikr feel slower. The fact is however, it is now much more controllable. If you're good, you should be able to actually open the throttle fully in first gear now.

If you really want a good improvement get a PCIIIr for your bike. You'll notice even more smoothness.

By the way, it is very normal to think the bike is getting slower as you get used to it.

Interesting subject...I live and ride at 5000'..Busa still rocks.
after awhile..it seems sluggish..but it's not..still does roll off roll on wheelies up here..good ones..last month in Monteray
with the wife on the back..it did awsome roll on wheelies with just the throttle...no on off..just roll to 5k in first.....and give 3/4 gas and up it comes...."OH WHATTA RUSH".....It's all in the mind.."Busa" Rocks....and it's stock..small airbox mod, punched out stock muff's, stock ecu.....never want a different bike "EVER"...And i am 52..my co workers say i should get a Lexus...."NOT"...Love the Busa...PaceM.

This is going to sound dumb but if you've never dynoed the bike before, how will you know that it's lost a small amount of power?

I think Mikey meant dyno the bike soon after ya get it......then if yer ever in hp doubt have it re-run.

It is probably that you are used to the power now, BUT it could be that the Throttle Position Sensor (TPS) is out of adjustment? Mine was[/QUOTE]

I ditto that Sierra I had same experience ;but as soon as I made this adjustment she started to bite again when shifting through the gearz. Check to see if the Throttle Position Sensor if off>>>>>>>> if so then adjust it to the correct position and she will be bite'n just like before.

Further note you betta start learn how to read your manual and try to do your own routine maint brotha cuz them monkey dealer tech dont have no luv for your baby like you do. If ya dont quite understand what your reading or dont feel comfortable playing shade tree mech just give us a hollaaaaaaaaa we got your back.

Lumpy,  180lb/ft of torque?? Maybe you meant 100?  180 lb ft with 150ish hp on a stock bus is not possible.

Hey dark, I'm no dyno expert or nuthin', but I think runnin' it on the dyno in first gear would have some sort of multiplication effect on the torque readin'. I'm sure that someone will correct me if I'm wrong, though.

I thought my '03 Was slowing down.Turned out it was just me getting used to it.Sad,but true.Still the best seat on the planet.

Doing a dyno run in first gear will not give you a very good reading. In Tucson, AZ a stock Busa will put out 147 RWHP in 4th gear. Mine put out 149.9 RWHP in fourth gear w/ K&N oil and air filters.
