Aftermarket Modifications advice

Post  spanna on Sun 06 Apr 2014, 5:37 pm

I recently bought an '09 1250S, the previous owner has fitted a GiPro (with ATRE), K&N SU6005 high flow air filter & Yoshi TRS muffler.
The cat converter has not been removed and there are no other add on to the standard FI module and the secondaries are still fitted.
Currently I am getting between 19 - 21 km / litre.
There is slight surging when the revs are between 2000 - 2800, I have checked the TPS position and it is correct, also TB synch was checked by a mechanic and is correct.
This bike has more than enough power for me so I am not really looking to improve performance.
My Questions are:
1. Will removing the secondaries solve the surging?
2. What effect will this have to the fuel economy?
3. If I remove the cat converter do you think the bike will run lean?
4. Has anyone used the Healtech FI tuner module?

Thanks for any help

I have a Yoshi TRS and when I bought the bike it had the TRS and a BMC filter (same as K&N).  Also had the GiPro ATRE.  It surged at low throttle as you have found and nothing fixed it until I added fuel with a TFI courtesy of Dale Walker.  All you have with the pipe and filter is a lean running bike running even leaner, so it will surge. Removing the secondaries won't fix that, although with appropriate fuelling, it is a great mod.

Removing the cat won't help with leanness.  Add fuel.  I recommend Dale Walker's setup, but you can get similar results with most fuel boxes if you want to spend time and money setting up on the dyno (Dale's is plug and play)

Fuel economy doesn't change much, but you will like the added power so will ride less frugally and with a big grin.  A couple on the forum have used the Healtech FI module and will no doubt chime in!

My 2010 bandit also has a Gi PRO with ATR and yoshi muffler, standard air filter,secondaries still in place, cat removed and get 22-24 km/litre, no surging at any revs also a 40 tooth rear sprocked, has allways been a smooth bike to ride so not sure about the surging on your bike, removing the cat didnt make it run lean, plug colour is still same as before i removed it

Thanks guys.
Hey kewwig, so you think I'm probably running lean?
I noticed a vecro patch near the battery, perhaps the last owner had a TFI and removed before he sold.

The stock fuel mapping makes the bike surge at the particular rev range that they test emissions at, because Suzuki wanted to pass the stink test.
A fuel healer will fix it right up, as stated.
I put in the Dale Walker fix (can't remember the name of the unit, next gen after the one with the pots) & it works a treat. So much so, I've forgotten about it. Plug and play. Under $200.

Yep, running lean.  Some bikes worse than others.  The TFI is a Dobeck

I also can recommend Dale walkers products, especially the stage 2 dobeck TFI conversion. It transforms the bandit to how it should have been without having to jumping through the euro3 emissions hoops.

The easiest thing for you to try is a better quality fuel.
Have a go at BP 91.

What fuel are you currently running?

My GSF1250 has never surged but I have never got better than 18km/l either so for some reason mine is slightly richer than other as stock.

Thanks for the thought
I have actually been using BP 91 does not make any noticeable difference to me from United or  Shell 91

Me neither but I was just making sure you were using good fuel as a baseline. FWIW 98 makes SFA difference to mine too.

Actually the higher octane fuels take longer to ignite but do make a bigger BANG.
If the vehicle is not tuned for 98, i.e. timing altered, it actually does not help

Well I'm not so sure about that. Well maybe in the bandit but not in a car I had awhile back
I travelled over to WA in a EL Fairmont. Drove the entire trip on premium fuel 95 & 98 whatever was available. Can't remember the exact details but I do remember getting some incredible economy figures from it.
I think around 8lt/100 or better than 900ks per tank.

And wouldn't the ECU adjust the timing somewhat?

Performance wise I can't tell the difference.

Plus I'm lead to believe premium fuels have cleaning agents in them???

Cleaning agent.  That's right. Fitted to the pump.  Clean out the wallet.

If you doubt it.

From BP's website

Main Benefits
• The high octane rating BP Premium Unleaded contains a detergent additive which helps maintain new car performance and minimize exhaust emissions. The detergent will prevent the build up of deposits on fuel injectors, on carburetor throats and on inlet valves and ports. This detergent additive will also significantly reduce existing deposits in a dirty engine.

I believe the 98 helps with fuel economy in a car, I tried it on my wifes car when new, economy better but when you worked out the added cost of fuel it was more expensive per km.
Will just have to take your word on that detergent additive!
I wonder if we add extra detergent to the tank if we can blow bubbles out the exhaust!!!
Would be great on a group ride, you'd never loose the guy in front.... unless you have a strong crosswind!

G'day Spanna. It's a subject that has little varied opinions, But most are around the mark.
In my opinion is your going to go down the Fuel Module track. Go with the main two with the runs on the broad!
*Power Commander, PC3 or PC5 or *Dale Walker's Kit's.

Most bike Dyno Tuner's only know how to use Power Commanders. Easy to tune. As they are very common and Plug & play, with base map in. 
But will have a go at anything if you are paying. pale  Some with nightmare results with other Module. No affraid 

Dale Walker, Uses kit's with lots of happy customs around the World.



Me, I use the PC3. Which made my Tuner happy, As he said the harder the fuel modules are to tuner, The more it cost you.

My setup is:
*Open airbox lid with K&N.
*Removed Secondaries.
*HealTech Gear Indicator w/tre "Advanced Timing Retard Eliminator is needed".
*Balanced TB's. My TPS was fine
.
*Arrow race headers with Yoshimura TRS.
*PC3 with the supplied map and these mod got 123hp with 115nm of torque.
*Neville Lush Racing custom tune = 130hp with 125nm at the Tyre (Standard 98hp/108nm at the motor).


It still gets good fuel consumption.


PS.

Hahaha! I've heard that VTR's blow big pink, But nice sounding bubbles!  lol!

I would say it is more like an injector cleaner built into the fuel recipe

 lol!  Its the quickest point to point bike I've had so I dont care what colour bubbles it blows and there is a bit more performance left in her.
Oh and it goes around corners too Reardo. Do you know what they are? Laughing  flower  jocolor

Have fixed that bad miss yet. It will go a lot better when you get it to run on all four!

No miss with mine mate. I fired her up in the garage tonight to remind the neighbours not to mess with me or they'll hear it at 6:30am every morning lol!
