Yoshi exhaust

So I bought my k5 1k and it has a full Yoshi exhaust, my question is should I get some kind tuner power commander or something? I know to maximize performance I should, but will the bike run smoother with one? It almost sounds like it has a slight misfire, not terrible but I think it could be smoother. Planning on changing the plugs this winter (along with a number of small projects) just trying to figure out everything I need beforehand so I can just order everything at once. Thank you!

Re: Yoshi exhaust

yeah, you need a power commander (or bazazz) and a good tune for full exhaust system

This is the first time I've heard of bazazz is it a new thing, less popular or am I just out of touch with the bike world?

Thank you, I did google and did some research on it, guess I need to spend some more time on the forums, I've just never seen anyone talk about it always power commander never bazazz.....at the same time I haven't been on the forums long

Next question, i'm semi familiar with car tuning and I know as far tuning goes you would want to be able to adjust fuel and spark that being said bazazz doesn't seem to have something to control spark am I correct on this? For my 07 mustang I can buy a programmer with software to adjust every single parameter in the car, is there anything like this for bike too? ie rev limiter, speed limiter, spark, fuel, etc I briefly looked at the power commander V does that have adjustments for all the injectors? Also can I make all the adjustments myself with their software for example see the tables and adjust as I see fit?


Sorry for noob questions just trying to learn as much as possible.

You need the ECU editor
Take a look at this site.
The software is free all you need is the interface harness it's only for Suzuki bikes at moment but they are expanding the models and the functions of the software it can already do what you have listed and more
http://www.woolichracing.com/
Download the software and register then you can download the bin files and have a look around the software all for free.
They sell the interface harness and log box you can ride all day and record data then at home download the data and auto tune your bike or tweak it your self. Read the web site for more info this is defiantly on my wish list! Beats PC3, PC5 and just about anything else.

So after talking to someone at a local bike shop, he said it must have some kind of tuner or have been flashed. After that being said I ripped the tank and seats off no sign of any power control, but I did find some unplugged connections under the seat. Here are some photos any ideas on what these might be to?

Re: Yoshi exhaust

The unconnected six and eight pin connectors are for the Suzuki Diagnosis System and the Suzuki Access port. They are normally unconnected. The two pin connector is for the license plate light, so you probably have none right now and are street illegal. The starter solenoid looks like it's not properly mounted as it shouldn't be sitting at an angle.

Why does he say that?

He said it would spit sputter and backfire on decel which it does not, though it does run a little rich and has a very slight misfire I mean about 4k rpm it isn't perfectly smooth, guessing that it needs plugs and it should clear up

Re: Yoshi exhaust

A backfire on deceleration could just be due to the PAIR system. I think that a system like the Bazzaz that has an oxygen sensor and a feedback loop for auto tuning will require that the PAIR be disabled/removed.

Fiddling around with fuel and ignition maps is doable but is not a trivial undertaking. Do you have a dyno?

Re: Yoshi exhaust

Since living in Dutches NY, you are fairly close to Max's BMW in CT. There is a gentleman who does a fairly good job with tuning, sells power commanders at a good price which includes install. His companies name is Dyno Solutions and he does work with Bazzaz also.

for some further information it has no sensors or connectors hooked to the exhaust anywhere, so it can't be auto tuned (as far as I understand) I havent found a loose wire anywhere near the front of the bike where an 02 sensor would be but the bike runs great, not sure if that helps and no I do not have a dyno

Thinking I might make an appointment to go over there and have them take a look and tell me just what the hell has been done so far.... Thank you for the info

You add the wideband sensor to the exhaust.
