Dyno Jet Kit stage 1

Well I have my bike booked into to sportscycles at Newcastle for a Dyno Jet Stage 1 kit and full dyno turn on next Monday.

I just can't wait to have it done to sooth the savage beast.  At the moment it is running too lean and popping all the time on the over run.

I did this to my previous bandit and the results were sensational.

I am so looking forward to it.

I think it will be $550 - $600 dollars well spent.

G'Day Greg, I had a 2004 1200s ( my only Bandit ) and the best money I spent was on a stage 1 jet kit and Dynotune. Soooo much smoother in acceleration and no popping on decel. You'll love it, happy days. 

He usually supplies you with a graph at the end, so I will post it up when I get it.  

No guessing of fibbing then,

will you get before and after dyno results?

I am pretty sure he does, he usually does a run when you bring it in then again after the work has been completed, it should take around 3 1/2 hours.

I think mine went from 97bhp to 111bhp. But just the way it became so smooth was amazing.

Greg PM sent.

Can some explain the purpose of dynoing a GSF/GSX, I understand that if you are going to race it yeah but for everyday use i am scratching my head.

A bike that developes 72kw @ 6900rpm and 108nm at 3750rpm is not exactly high perfomance material when you compare it with a modern sports bike, my old GSF and my current GSX pulls like tractor from the hit of the starter, i can start off without slipping the clutch from a dead start in 4th gear, i can go from a 100kph to 180 with a twist of a wrist and get there bloody quick in top gear.  And i can keep up with most sports bikes.

So based on that why the need to have it tuned on a dyno, is it going to give you that much extra performance for bike that is built to underperform from the factory. Surely is one or two hp extra worth the expense

I could under stand it if you gave it a front and rear ohlins make over but a dyno no, So if some one would be so kind to educate me on the benefits that would be very interesting.

And by the way give me hi torque figures and day i just luuuve the grunt

It's about getting the best out of any mods. Tuning AF ratios etc. You can say the same about putting a timing light on a HQ Holden. It might start and get you to work etc but are you getting the most out of it?

to optimise the running of the engine which is compromised from the factory. Increased torque,hp,smoother operation and increased fun factor to name a few.
You dont need to ride the bike flat out to enjoy the benefits of a good tune.
I'm about to go down this path myself probably with Holeshot Performance and some good info from here.

I had the dyno jet stage one kit installed yesterday and more importantly I had the bike dyno tuned.

The difference is amazing.

My bike was running lean an had to stay on the choke for a long time when starting from cold, I knew this when I purchased it and factored that into the price.

It would always pop and crackle on the over run, I don't mind a bit, but it was excessive.

Jamie at Sportcycle started work on my bike just before 9am and it finally came off the dyno ready to go at 5pm.

He is a perfectionist.

He must have done in excess of 20 runs on the dyno.

He did a base line run,

Then installed the kit, back on the dyno.  Not happy, it seemed like it was getting too much air, so he played with the air box, back on the dyno, this proved it was not the air but needed more fuel.  This went on an on, in the end he used larger jets than those which came with the kit and this got it nearly right, but it still had a bit of a hole between 4500 and 6000. So he raised the needles one more click and presto a beautiful straight line.

He also suggested that I give 95 octane a run rather than 98, he said that 98 suits shorter stroke motors, where as the 1200 with a longer stroke should suit it better and make more power.

I am just waiting for them to email me the graphs so that I can but them up.  From what I saw it was producing 110 hp 

but it is really all about the torque and how it produces the power, as I said the power is now in a straight line on the graph, no dips or holes.

And what it is like to ride,

It is a totally different bike, power everywhere, so smooth and turbine like.

Cool bananas.

Sounds good and if it makes power in real world conditions all the better.
Too often we get sucked in by peak numbers.

And I forgot to men tion the best part.

The price.

Now I know that they charge $105 an hour, so as the day past, I started to worry about the cost.

But when I paid the bill I was very pleasantly surprise.

$633.00

Now that included a new K and N filter, a very reasonable $83.00 and $185 for the dyno jet kit.

He only charged me for 3.5 hrs labour at $365.00

A fair bargain I say for the improvements that have been made.

Yes Jamie is good to deal with, I usually get my pink-slips there because it's not far from my home.

One time Tex and Bundy were there getting the 'Busa tuned.

It;s amazing, you look at the graph and think, well, so,  but when you ride it, it's like wholly sh.t, what a world of difference.     

And it was actually 30 runs on the Dyno............

A short clip of one of the early runs on the Dyno.
