gs EFI, step by step, sloooow and steady (formerly: hating the gs)

[wladziu]

Alright, Occam's Razor: the simplest answer is usually the best.

If your carbs are causing so many problems, then choose the simplest way to fix it.  It's probably what will make you the happiest.
Whether it be selling the bike for something with FI, or just beating the dogsh!t out of the GS because it keeps breaking down.  
Whatever is simplest and gives you the most happiness.

That's the vein I have been on in this thread, Mrs. Super-Duper Moderator.  


If I knew more about carbs, I would help with that.  But, this is what I know.  And, it seems like that's what you needed to hear, or you wouldn't have posted your problem in such a manner.  

I was trying to have fun with you and kid around a little.  You're a smart guy, and I thought you'd be smart enough to see the humor.  I was TRYING to get past the argument that we had before my hiatus.  Apparently, you're still holding onto it.  I was really trying not to let you lead me into another argument, which I have problems with, but apparently, you succeeded.  


If you'd back off of me, I'd be more than civil with you.  I like the ideas that you have, and I like talking with intelligent people.  However, being as smart as you are, if you don't acknowledge when someone is dealing with some difficulty - why should I worry if you "run and tell" to have me banned?  
Has it passed your mind that I may not enjoy being like this, and would appreciate a little help?  Or is it just funny to poke me and watch?  
You've shown me the latter.  





Good luck on your problem.  Hope you find your answer.  
I'm dealing with carb problems of my own, I know how frustrating it can be.

What are the mods to the bike. I am pretty new to this carb thing, and rust. But I had great success today.  I though I saw you mention the spec of the bike isn't stock.

i've had enough non-riding weekends now that looking at the gs just brings feelings of hate. hate the carbs, hate the damned carbs, hate hate hate the carbs that are never ending problems.

sure, we had some fun times. sure, i learned a few things. i just f%$king hate the sight of it now. i'm still trying to get it running. a week here and a week or three there of flawless riding interrupted by a couple months of bulloh my goodness fiddling isn't acceptable anymore. 

had a dream about it 'accidentally' falling out of the truck while traveling at 70 mph last night. it was sweet !

(post your hate here if you like)

[94suzuki500]

maybe you messed them up...if its happened 3 or so times it sounds like mechanic error not mechanical error...the carbs are soft so if you messed up any of the jets or anything like that, it will cause it to not work right, they are precision made and dont tolerate much error.  I havent had any problem with mine when i had it, and i rode mine hard and worked on it all myself and not a single problem

[The Buddha]

Thanks for all this info - I got em yesterday - I am splitting them tommorow - prepare for questions and might as well send me emai ID for pics.
Cool.
Buddha.

you got someone's carbs, mine are out there on the bike... just so there's no confusion

thanks for the o-ring pack n stuff buddha, things fit nicely except for the emulsion tube. it was a little tight, no big deal, still worked fine.

Yea I thought you were xtalman - my bad.

Emulsion tube was tight - well its possibly tight compared to the squished stock one ... never had any trouble with it - ever. But you fit it and it sits there and seals up - that's all to it. You make sure it sat nice and tight inside the grooves ?
Anyway - set your floats right - blow test em. Guys all the people that hate carbs over fuel injection - sorry, I cant help but say ... meeeeeeh ... seen FI, not impressed.

You need to ride a bike I have set up with carbs - no way a FI bike ever runs like that ... ever. In a way, I'd fit FI sport bikes with a large FI and a small 24-25 mm carb for 2 cyls per. Remember in the old days yamaha used to fit their big singles with a 36-38 carb and a 24-25 carb. I would fit it on a large sport bike. An SV1000 could easily use one of those.

The slow and shut open shut situations - nothing like a carb.
Also you oughta compare your 15 year old GS to a 15 year old FI bike that almost has had the same life as yours. No sense comparing a 15 year old GS to a new GSXR. Like WTF.

Cool.
Buddha.

Well, for now the gs hass become an efi project. I don't have enough bike knowledgre to pass judgement, so I'm giving it a go.

Wife says I need another ike that isn't a project so I can unwind... love that gal !!!!!  ))

[intergalactic]

whatcha gonna do? Megasquirt?

is there enough power from the generator to run an EFI pump?

If you send me the carbs and 0-25 bucks I will make it sing. Shipping not included.

I can test run it on the K&N and pipe GS I got, but its gonna cost ya 50. Shipping not included.

Putting EFI on a bike with carburetion problems is like marrying a girl who has quit sleeping with you as a way to get sex.

Good luck there Ohgood. I dare tell you, you dont figure carburetion you sure as hell wont get EFI to work. You got somethign simple going on there that you seem to be repeating each time you pull it apart.

Cool.
Buddha.

How come bending the tab doesn't change the float height ?  Doesn't make sense

es and no. One of the newer versions is now called MicroSquirt, and it's supposedly spark -and- fuel, along with a few neat logging features and on-the-go-tuning that should make it fun. It's not cheap, so I'll work a little overtime and sneak the cash into the I'm-not-smart-enough-to-know-better-efi-fund. THe wife approves, and buddha has doubts, that's good enough for me

good question. there isn't much left after the headlight and all. I'm assuming i'll be ok, with a motorcycle specific pump. assuming does a lot

i almost fell off into the lathe after reading that one. ya, i know. i slapped one of the spare sets of carbs on the bike this afternoon and it ran better. not perfect, but better. still going with the projet though. i just gotta see the end result myself. hard headed, whatever, yes

[ohgood]

How come bending the tab doesn't change the float height ?  Doesn't make sense 

eggzackery. i don't know what would cause the float height to -not- change after bending the tab. it's a pretty simple deal there. one side reacts predictably, and changes, but the other side, nothing. it's about 1/4" to 3/8" above the gasket, which according to what i'ver read is too high, and prone to flooding.

getting the worms out of hte over-flow tube helped, but it's still far from perfect. to tell hte truth, i'm just sick of 2-3 months of kinda-decent running, then a month of chasing gremlins, then winter, etc

i'm just hoping to make the gs a little more fun to ride nad easier to maintain.

[wladziu]

Has anyone here ever tried putting in longer windings/changing magnets to squeeze a little more juice? 
Not too knowledgeable about motorcycle ignition, but switched my old jeep to EFI.  That microsquirt's the way to go, if you get enough juice to run it. 
Good luck on making the harness.

I assume you diagnosed with other sets of needle valves , same results ?

[bettingpython]

FI>carbed any day of the week.

Buy a 600 and be done with it.

ya, the needle valves seemed fine. close inspection under a strong light (and magnifier) didn't show any differences.

just went out and started it a few minutes ago. it fires up the instant I bumped the starter, idles smooth and nice at 1200 rpms, but any throttle and it starts coughing and getting rich. a little more throttle and it will just spew black smoke (overly rich). float height has me confuzzled as it isn't changing on one side. guess I'll piddle with the other two sets of carbs @ work while I wait for cuts to finish, and my new efi goodies to arrive.

i have new information that i'll need 4-5 amps for everything. ouch.

sing it man !

ya, I'm looking everyday. either a sv650 slips by while i'm at work, or an f4i slips by while i'm putting kids to sleep..

i'm not bike knowledgeable but, i'm curious. it's your money, blow it how you want. but, i think this project is similar(in respects to cost) to one i wanted to undertake a few years back. i had an '89 hona accord. i wanted to switch out the auto tranny for a 5 speed. apparently there is more involved than just dropping the old tranny and hookin in the new one. expensive differences. so i chose not to. i'm just wondering if the money you'll spend on this project would buy you a more up-to-date-efi bike that you'd enjoy more since the GS is giving you such a head-ache.

yep, it's involved. it won't be a weekend, or a half dozen weekends. i'm guessing sometime in 2010 i'll have a working, fuel injected gs500. will it be perfect ? i doubt it. will it be a learning process ? yes, most definitely.

that being said.... I'm editing my first post, and hoping one of the moderators will change the topic from "hating the gs" to "gs EFI, step by step, sloooow and steady". thank you.

[The Buddha]

I have tried it with a GSXR rack - too many weird sheite on new FI bikes ...

Anyway, the float tang not moving, and a good sealing up float seat = a float seat that has a rough inside ... or the float needle has a rough wall. Some thing is jamming.
I'll bet I'll fix it - and did you do a blow test for floats.
Cool.
Buddha.

[intergalactic]

I was little bit involved in the efi-332 project which sort of morphed in to mega/microsquirt. If I can find my old emulator box, iI will send it to you. But I think I pitched it.

whatcha gonna do? Megasquirt?
