I do alot of playing on the highway, and every now and then I will run it down the track...
Im no pro... infact I almost feel out of my league by posting here... but like you guys... Im a speed freak.
I want to change out the sprockets... I want more ass end power AND i want more top end.
Help me?

Do you want more ultimate top speed or more acceleration up to top speed?
Do you have any mods to the bike?
What times are you running at the track?

Im getting my butt kicked in the 1/8 but Im beating them in the 1/4 mile.
I want more top end too. I dont want to just be a track back.
right now I have Vodoo slip ons.. yea... i know they suck. and a power commander 3. im lowered and strched 6 inches.
i want this thing to Fly both in the short game and top end.

187 mph is not fast enough? I had mine at 175 and that was all i wanted. I like to get out the hole but that top end stuff is for the birds. Good luck with that.

Sounds like you need to practice if you aren't getting the holeshot... :oh yeah:
If you want some more power, get a decent exhaust and toss that Vodoo crap in the trash.
Post up your time slips, that would be a better help on your riding ability...

OK I'm surprised the Guys haven't chimed in with the obvious yet:umm:
Start with gearing. IF you gear the bike for faster acceleration you will lose top speed. If on the other hand you gear the bike to run higher top speed you will have slower acceleration. Simple fact.
The gearing you have now is a compromise between controlable acceleration and useable top speed.
Speaking of top speed do you have a XT.R.E.?
Really are you going to be drag racing more or tearing down the highway at 190MPH more?
If you want to add to both then you need to add HP which will add both acceleration and top speed.
Cams?
Nitrous?
Big Bore kit?
Airbox Mods?
Ram Air seals?
Oxygenated Fuel?
Racing tires?
Ignition controller?
Launch control?
on the fly mapping to allow changes at the track?
Ceramic Wheel Bearings?
NON O Ring chain?
Lighter wheels?
Go on a diet?
I guess it all really boils down to what your willing to spend in $$$ and what your willing to live with on a daily basis.
But hey what do I know I'm just a Girl:laundry:

The only way your going to have both - track speed and top speed is a power adder. nos -cheap ,turbo - high dollar or engine mods - high dollar.good luck

If you are getting beat for the first 1/8th mile, you have more power than you can use. With a stretched bus, almost nothing should beat you to the 1/8th mile, other than another stretched Bus(or 14, 1000)
Practice with what you have first.
What times are you running?
60 foot?
MPH?
and as others have said, you will need a power adder if you want both top speed and acceleration, gearing is only a band aid that will only work for one.

I wouldn't add anymore power until you can use what you have. If you can't ride the current power level to it's maximum another 30-100whp is only going to make it worse (if not hurt you)....

OK on a more serious note. You probably won't be running 180MPH on street often and probably shouldn't. So I would say make a small sacrifice in gearing to get harder launches, yes it's going to cost you some MPH on topend but it will make a huge difference in drag style launches. But then again I never drag raced(Yet,,,, it's coming)

I agree with Marie. Alot can be gained by just being experienced at hole shots. You can add hole lot of ponies, but, if your reaction is off...you loose some of the gains you just spent on your bike. Lighter wheels, rotors anything unsprung weight will give you a 4x advantage over items that are light weight but added to chassis area. loosing 10lbs equate to 1hp gain. Find a racetrack near you and sign up for some night drags. Practice and you will find the busa is already well equipped to run extremely fast times, 1/8, 1/4, or otherwise. Just my 4 cents. Drew.

What's your gearing?
If you go up one tooth on the rear, it will give you a slight advantage in the 1/8th without giving much (if anything) in the 1/4.
Stay with the stock stacks (or maybe even go with two longer ones) to give you a broader torque curve (you'll lose .5 - 1HP on top but you won't notice it).
Strap the front end and launch it harder and work on your 60ft - that's where it's all at on the 1/8th - 1/4.
To get more top and bottom end - stay with your stock gearing and bump the power a bit. Full exhaust system, degree your cams, and a dyno session would net you 6-10 HP. Staying with stock gearing vs. gearing it down for more 1/8th mile performance and adding this power would net you acceleration across the board while maintaining top speed.
For ultimate top speed performance on the '08 with your level of mods, go up one tooth on the front sprocket (stock rear). You'll lose acceleration but you can't have it both ways without spending money.
Quicker, Faster, Cheaper - pick any two.

I'm curious what his time slips look like before I recommend any changes. If he's got those mods and only running 10.5 in the 1/4 or 6.5 in the 1/8 then he needs to learn to ride the bike. Dropping a tooth to make the bike more wheelie prone, isn't going to help him learn to ride any quicker. Now if he's maxed out and running 9.2 and 5.8 then a gear charge could certainly improve things IMO....

ohhhh c'mon...what's wrong with wheelies?

As already suggested, I would like to look at a time slip and know what the total bike / rider combo weighs before offering any advice, but my thoughts on gearing are a bit different. Now that Petrik has offered the re-flash software for the GenII, we can get rid of the damn soft limiter that used to creep in around 11,200 (11,800 indicated) and rev the motor safely to 11,500. My ECU has been reflashed for a couple of weeks now, I have been running nitrous passes on my GenII right to 11,500 with no problems, and no discernable drop in torque. Extra revs means you can (and should) give her more gear. I'm now running a 16/44 combo, and may go up to 16/45. A 16/44 will go 163 in 5th and 178 in 6th at 11,500. When I go to Loring in 2 weeks, the gearing will have to change, but 178 in 6th is still pretty respectable and will get you locked up in Massachussetts for at least 6 months.:oh yeah: I would need more info to give specific advice, but gearing is the cheapest way to turn available HP into usable thrust. Its also easier on clutches, because generally speaking, you get the clutch out faster. Agressive launching with stock gearing is HIGHLY abusive on the clutch.
Of course all this assumes that the chassis is balanced and working well...

I know everyone will argue with this but, the guys i know with the fastest strip times have geared their bikes higher.... one or two down in the rear... now they can launch the bike at a higher rpm and control the power better. This would also give you more top end if you really need it. I get nervous at about 140 so mine is plenty fast for me.

on my 08 busa , i geared down one in the front, and put the R1/R6
throttle tube on it . really woke the sleeping giant for me
