Neal Posted October 23, 2017 Posted October 23, 2017 Hi can some kind soul tell me what this is please Quote
Hoggs Posted October 23, 2017 Posted October 23, 2017 seems to be the second air unit https://www.fowlersparts.co.uk/parts/5929278/gsf-600-bandit/second-airnow I suppose the follow up question is what is the second air unit Quote
Tango Posted October 23, 2017 Posted October 23, 2017 Yep....looks like the secondary air injector unit......This is for emissions. .......I've removed mine on the Speedy, had it disabled in the ecu and blanked off the ports in the cylinder head...... Quote
leener Posted October 23, 2017 Posted October 23, 2017 Yup. Don't need it... Oh, ship. I stuck the 10130 power map on my RS the other day to see if it would improve things (which it did), but forgot to check if there are any settings I need to change, because mine has no SAI... Quote
SlowBusa Posted October 23, 2017 Posted October 23, 2017 This is for emissions. .......I've removed mine on the Speedy A common mod to do....mine went in the bin as soon as I got the bike Quote
Stu Posted October 23, 2017 Posted October 23, 2017 All the above are wrong! Its actually a PAIR valve!! Suzuki's name for a secondary air injection unit Its the same thing remove it if you don't want it and make some blanking plates it is there to add fresh air from the air box in to the exhaust to weaken the emissions Quote
Neal Posted October 23, 2017 Author Posted October 23, 2017 The hose going from it to the carb had split would this be the reason my bikes been running crap (loss of power, stuttering, miss fireing ? Quote
leener Posted October 23, 2017 Posted October 23, 2017 The hose going from it to the carb had split would this be the reason my bikes been running crap (loss of power, stuttering, miss fireing ? I would say that a split hose anywhere, particularly to the carb is probable cause of said symptoms. Removal is the way forward. Quote
Tango Posted October 23, 2017 Posted October 23, 2017 The hose going from it to the carb had split would this be the reason my bikes been running crap (loss of power, stuttering, miss fireing ? Possibly. Try blanking it off and see what happens..... Quote
SlowBusa Posted October 23, 2017 Posted October 23, 2017 On a Hayabusa you can blank it off with "The Marble Mod"A split will probably make the bike noisy ...Do you have an unexplained ticking? Quote
Stu Posted October 23, 2017 Posted October 23, 2017 On a Hayabusa you can blank it off with "The Marble Mod"A split will probably make the bike noisy ...Do you have an unexplained ticking? He has a split between the valve and the carb resulting in an air leak in to the carb If it was the other side of the valve you would get the ticking Quote
Tankbag Posted October 23, 2017 Posted October 23, 2017 On a Hayabusa you can blank it off with "The Marble Mod" What's the benefits of blanking it off ?As a side note I was told the PAIR system was responsible for a nice flame out of the exhausts on high revs roll off Quote

SlowBusa Posted October 23, 2017 Posted October 23, 2017 You know how some bikes sort of make a backfire sound when revs roll off "a popping noise" Its supposed to stop that........I dont have it but some do (dependant on after market end cans) Some love it others see it as a fault (which it isnt)Blueflames would be the same thing.......hot exhaust gasses having more Air added makes it do it.....and marble mod stops the air being put into the pipesIts just a personal preferenceAlthough I have had Blueflames out of my "Evo Blueflame" end cansThe last thing Im doing is looking in the mirror to see if it does it at high revsEDIT: Same As Stu says Quote

Tango Posted October 23, 2017 Posted October 23, 2017 With mine when the SAI had been disabled but before I blanked the ports off it was banging on the overrun.....I mean proper loud.....so I got fed up with it and removed the SAI valve assy and blanked the ports.......but I could have also achieved the same with the marble mod as [mention]SlowBusa[/mention] said.......but I just wanted to get rid of a bit more garbage from under the tank......

SlowBusa Posted October 23, 2017 Posted October 23, 2017 @Joeman Ive heard the BMW S1000RR does it as stock to a certain extent..(but obviously not loudly)...did yours before you fitted your Akro's? Quote
Joeman Posted October 23, 2017 Posted October 23, 2017 @Joeman Ive heard the BMW S1000RR does it as stock to a certain extent..(but obviously not loudly)...did yours before you fitted your Akro's? Mine (2013 model) didnt with the standard exhaust but the 2015 models pop nicely when slowing down. no flames though - not good for health and safety i guess!With the full exhaust mine was crazy - loud pops, huge flames, really entertaining but not practical so i had to block off the air supply to stop the air getting into the exhaust.But, there is a solenoid in there. my idea is to have it switchable, so i can flick a switch and go from mildly antisocial, to flame spitting monster!

SlowBusa Posted October 23, 2017 Posted October 23, 2017 How cool would it be to have a switchable exhaust sound !! Quote
Joeman Posted October 23, 2017 Posted October 23, 2017 How cool would it be to have a switchable exhaust sound !! easily done too on the S1000RR.. just need to wire a switch to open/close the valve... Quote
Neal Posted October 25, 2017 Author Posted October 25, 2017 The fixing the hose cleared up the problemsNot sure to remove the thing yet can’t find no blanking plates on eBay ? Cheers for your help fellows Quote
