Hi All

A TRE will not be enough if you put a full after market exhaust system on it.
A TRE affects the timing only, it doesn't change the bikes air fuel mixture which is what will be required if you enable the bike to breath better with a high flow air filter and full exhaust.
You will need to re-tune with either a TEKA unit which re-programes the on board ECU or a PowerCommander which alters the signal from the existing ECU.

If you've got a stock bike with a slip on replacement exhaust ( ie not a full header to bum replacement ) I wouldn't recommend a Powercommander as it wouldn't make a lot of difference for the amount of money you are going to have to spend. I got my first busa re-tuned with Welly Motorcycles TEKA unit to tune out the flat spots at low revs ( where they do all the emmission control testing ) and it smoothed it out around town a much cheaper option.

If you decide to buy a powercommander I got mine ( and the exhaust ) from
www.onlineparts.com. The Powercommander was about $450nz from the states but over $700 from any place in NZ that I could find.

Hi again

False neutrals between 5 & 6 seem to be a common problem with the busa, and not one which I have ever heard of being fixed. If you go to www.hayabusa.org you will find tons of posts with the same problem.

So I decided that I needed to deal with it.

On the two busas I've had it happened most frequently when I was short changing to 6th
around 4000 - 6000 rpms with the gear box not under very much load and I did a bit of a wishy washy gear lever movement.

It never happens when I'm accelerating hard and shifting. I've come to the conclusion that the big Suzuki's likes having some power going threw the gear box for it to start behaving.

I find pre-loading the gear lever before shifting greatly reduces the false neutral and also makes the gear change very snappy.

Try this next time you're out.
While in 5th and still accelerating put some upward pressure on the gear lever as thou you were going to change. As the clutch is still out it won't move as the gear box is under load ( it will if you're not accelerating ).
Now with the pressure still on the gear lever, change gear ( clutch in, drop revs etc ).
You will notice that as soon as you unload the gear box it will click into gear.
If you're accelerating hard it will snick in real quick, if you're putting around it might clunk in a bit but as long as your are firm with your pressure you it should go in.

I'm always a lot firmer in my 5 to 6th gear changes now and I rarely have the problem.

Hope it helps

BusaJim.

i had a false nuetral 5th to 6th yesterday - mid power, about 180k. i just put it down to lazy changing.

new pilot sport on the rear - scrubbed it in and rode to tauranga. full on (well for me) over buckland rd and up the kaimais with no sliding or worries, but pretty squirrely in the hotter tar in the afternoon - probably not the tyres fault.

anyone else got a harmonic between 4800 and 5500rpm?

Just keeping the thread alive I've done 2000 kays on mine and the gearbox has settled down nicely and I havn'rt seen a false neutral in a while (maybe me getting used to it). The back tyre is taking a severe beating as expected so looks like this will be an expensivee consumable item. Another web forum suzukihayabusa.org/ also has some interesting stuff on it. There appears to be a bit of an achilles heel in the Cam Chain Tensioner with a recall mos being done. Mine is a little noisey in that area but not enough to worry about (owned clattery old Suzukis fo 20 years now). Anyone else had any experiences in this area..?

New owner here.......

've done about 500kms on the bike so far in the last 4 days and found only two problems. One is the front brake bite is not as good as I want it to be. Any advice on brand and type of brakepads for replacement?

The other problem is the seat sticks! It is so sticky that getting off the bike is very hard and make me just want to keep on riding.....
Oh, and I tend to get disoriented when on the bike, and finding the shortest road home is always a huge problem.

**terbang** · 7th March 2006, 09:22

Have the same prob with the disorientation and the seat..:slap:

Marmoot we put a set of ebc HH sinsted in front of father in laws busa, made a huge difference.

**Balrog** · 7th March 2006, 11:35

wonder what these would be like

**Cajun** · 7th March 2006, 12:41

if i you were gonna do that, i think it would be best to put a set of gsxr 1000 front end with radial mounted capilers and like on first.

Thank's Cajun. Will certainly do that in the next pad change. EBC HH.

Anyone got experience with braided brake lines as well while we're at the brake topic?

Edit: *droll*.........on the brembos........*count money on wallet*...............*cry*..........

**Cajun** · 7th March 2006, 14:23

Yeah braided lines also make a difference in braking feel, really depends on how far you go, i would change the pads, see how that goes, remember the busa as 6 pots, if you still not happy put on lines. by that stage, you be ready for fluid, or even change the brake fluid when you do the pads.

I changed the fluid in my bike couple of weeks ago, it just made a huge difference, from going factory fluid to ebc dot 4, i close to doubled the feeling by just fluid (already had ebc hh pads)

**terbang** · 7th March 2006, 14:55

Braided brake lines and decent pads have made a lot of difference on other bikes I have owned. Soon as I'm over the warranty thing on mine I shall do the same..
