[Group] SUZUKI GSR 400/600

[Orleng]

when im slow in change gear, especially from 3rd to 4th.. and the rpm drops until very low.. the pick up suddenly increases when the rpm is 5-6 compared to maybe 3 to 4000rpm... almost feels like got "vtec" open

or the torque significantly increase? i understand certain bike have different power at diff bandth but mine doesnt feel gradual

 

if this information has been posted before already, please forgive this repost, haven't been through all the pages on this forum. was looking for info to tune away the snatchiness.

 

have been reading up abit on this. the ang mohs call it the "herky jerky", can google for it. supposed problem with Suzuki FI models?

 

apparently what happens is when engine speed is above 4k rpm and you close the throttle, the injectors go into "off" mode. when rpms drop below 4k, the FIs turn on the injectors in "idle" mode. if you close the throttle above 4k rpm then open up again, the injectors take a second or so to turn back on, and they discharge fuel at the "now" position on the throttle. So it causes the bike to surge at that point, when the fuel injectors suddenly pump in the fuel dependent on the current throtle pos.

 

supposed fix is to adjust the TPS so that the TPS indicator in dealer mode is just at the top position when the throttle is at the "idle" position. this makes it such that the ECU never sees the TPS at "idle", hence, never ever shut the injectors off as in the above scenario. which eliminates the throttle lag and snatch.

 

according to info off the net, it was done this way for emissions purposes.

was trying to fix that when i was doing a throttle body synch. problem is the TPS sensor is apparently blocked by the frame on the gsr4. cannot get to the torx screw without unbolting the throttle bodies and removing it. anyway, after the throttle body synch (cyl 1 and 2 were way off), engine became much smoother at idle. really love riding it now.

 

manual was a little deceptive, says there are balance screws, but all there are are idle air screws.

 

just to share, left is pre-TBS, right is post-TBS.

Very informative. This is what I am looking for. I realised it too whenever I change gear the RPM goes very fast to idle speed and when on the next gear, I will get a surge effect when i open up my throttle. Thank you so much for the effort.

seraph - no lah not paranoid lah.. in fact i didnt notice until another bro here helped me inspect. he say dun need to be until dripping.. leaking also can be a problem..

and Orleng.. thanks for the advice.. don worry about repost etc.. for goodness sake..this is a forum.. there is 36 thousand post here.. i did my research end up i might not even be looking at the right place.

but hoh .. removing throttle body is very chim for me.. any chances i can learn from u? or for 4th gear drag higher so it won close the FI below 4000rpm?

 

u mean he teach u and do for u rite??

nt he teach u and u do it yr self??

eh, i haven't tried removing the TB yet, too much of a headache already that one. my TPS is fine afterall, just outa synch TBs is all. I just followed the manual. actually, it's fine if you don't close your throttle entirely when you clutch in. it's only when you close throttle all the way from above 4000rpm, that the injectors get turned off.

 

i might take a look when i decide to do valve clearance. but that's in another 10-15k km.

nps, it was annoying me for awhile too, thought it was TB problem, went to google, and learnt alot. trick i suppose is to not shut off throttle entirely i suppose.

 

but i haven't been riding this bike for long, still learning.

anyway, decided that even though my name is orleng, i was getting a little tired of an orange backlight. did a little googling and......

for goodness sake.. u don understand english meaning of learn from u?

m*****ak's friends i supposed?jus because i asked a question that was posted years back and its perfectly normal to not to find it. since u so clever u imrprove the search function

will u guys grow up and learn to know a person before u judge them? or "helpful" one day n trigger happy when u didnt get laid e nite bbefore. during bone's DIY during many of the process i asked him let me hand on myself. Lin was also there. this is digusting. rather than keeping a forum for what it was meant to be. bringing ppl with the love of bike together to share their knowlegde. ppl are forming clicks or to you, your definition of share is actually exchange. so newbie are not welcome.

 

no wonder the tread got closed before

 

Shut the F up dude... U're annoying.. And u annoying everyone with you never ending questions. PM here PM there.. Call here call there.. U think every1 owe u sumthing issit? Must answer to your every whim. No wonder the bikeshop chop chop u.. One look at the bike we all know your bike is an accident bike.. So many issues with it.. And that oil leaking is jus a small sign of bigger things to come. Just take my advise and trade it in for a REVO...

the tread closed coz of idiots LIKE U!

during diy u ask ppl to do it for u...

ya they teach u...

BUT THEY DO IT FOR U!

and once they teach u u forgot it already.. u say it yrself during diy..

since u want to talk about english?

correct yr spelling before correcting other ppl english...

even if CLAIM that u want to hands on..

then u should do it... nt let them do... VOICE OUT! and force yr hand to be on it...

 

 

asking questionover an over again is a whim... like u

[Guest motofreak]

Seriously u should just sell off the bike... Not that i hate u but its obvious its an accident bike.. The bikeshop managed to cover up nicely so people like you would buy it. Now that u holding it beyond a month or so.. U start seeing oil seeping out... Sell it.. Get an MP3 again.. gillera or auto scooter... Sumthing that u familiar with...

 

Plus the reason the rest stayed quiet is cos they cant be bothered. In fact most just skip your posts.

I couldnt agree more.. What DIY... Its more like asking everyone to DO IT FOR YOU... Seriously dun come for any other DIY.. Your are just an annoyance.. Hands dirty a bit cannot lah.. Must get people to take things in your pocket for u lah.. F lah.. Grow up dude. Want to DIY but scared to get dirty. Even a gurl gets her hands dirty fixing up her OWN bike..

dismantling + prep

 

Question bro.. Where u got the micro LED? And how much was it?

[helmy23]

Wow!!!!!!!!!!!....forum getting exciting again!!!!!!!

[EJ]

Relax guys.. Insomnia kicking in so i logged in and see the forum, once again filled with anger. Where is the love?

[EJ]

strangly your name is everyone, funny thing is i only remember asking ppl who are helpful willing to help. so asking questions is whim. its strange u can post so much back in 05 and 5 yrs later suddenly u are expert and start shooting ppl

ironically in the poll to reopen the thread, someone quipped that a thread should be for discussion and not for aggresive behaviour

 

Relax dude.

 

I've been in this group forum since late 2006. Back then, there were no DIY sessions. Only meet up, eat, ride around. There were a few occasions where DIY was being organized but they were breif unlike Bone's which can last the whole day!

 

I wanted to fix LEDs on my bike so i went about and asked the guys (earlier ones), nobody entertained me. One even discouraged. So what did i do? Learned it myself! Burnt a few fuses, dismantled the tank and wondering how to fix back. Mind you, i only had the japanese manual and had to rely on translating the pictures..

 

Now, they have english manual meant for the 600 but its just as useful. Some of the guys still take the effort to answer your queries so take it easy..

To daniellovestodance: bro, it's takes time to create bond n trust. I believe it is just a small misunderstanding only. If u need to clarify things, u may pm me, i'll see how much I can assist.

 

aside to motofreak: we r just like a family that love our bike, so (no heart feeling) pls try not to use the word F etc. We r meant to share our interest & making friends ( u know what i mean) I mean no offences bro hope u understand where i'm coming from

 

We are GSR = GOOD SOUL RIDER

[Seraph]

In case you failed to notice, everyone got along fine before you came along. So I suggest you give that some thought instead of feeling victimized.

Hi fellow GSR bros,

 

 

I can sense that there's a small dispute here, I personally think that it's not fair to close the thread immediately or issuing infractions pts to prevent more burning flame,But if this argument goes out of control then it leaves me no choice,and just think that (if) there is some new member who just bought a GSR recently and wanted to know more ,saw whatever replies we have here,would leave a bad impression,Right? nevertheless i would appreciate that we maintain our harmony just like before.

NOPE.. he is not annoying EVERYONE.. and for the last time, stop calling others name or use vulgarities. dont like then dont read la or u can jus juz ignore it.. like few of the GSR riders here, they do read but dont post coz they dont bother..many dont turn up for meetups due to some reasons, one of it is this one...

 

doesnt matter if its an accident bike or not..coz ur bike is also an accident bike beb... and how do u knw small oil leak is a sign of bigger problem to come? assumptions eh??

 

so, juz chill or rilex beb... im on noone side...

frankly speaking, for once i agreed with what you (daniellovestodance) said bro..

n yes, the thread got closed b4 due to many issues...people start to think they knw soo much and alot more.. but dont worries, there are still good GSR riders out here who can help with no issues...

see la..untill another moderator comes in.... for some who complain to the moderator and asked him to close the thread, pls solve ur problems rather than asking someone to close the thread... and those who uses vulgarities or names on others, pls stop.

No Need to get so worked up on this kind of issues beb. DIY session, we show or tell n they do.. they CANT do after trying, we HELP. if not we buat bodoh sua la..

FYI, DIY sessions, dont wear nice nice expensive attire.. sure get dirty...

 

peace bro peace..
