hey back in the day, someone said they'd give good money for a fedexable kit to EFI a GS. How much is good money? What if it was done with COTS parts (commercial off the shelf)? Like GSXR throttle bodies and fuel pump with cheap controller. 250? 500? 1000? Name your price.

I figure it would be around 500 not including labor.

ice did his fi and turbo system for about that in oz$ if you can get the bits second hand it doesnt cost much, its the setting up thats the Buddha Loves You

$500 would build you a pretty badass megasquiurt.

How much would I spend?  Not a penny.  My carbs work fine, easier to fix too.   

Easier to fix but you have to fix them alllllll the time.

Carbs are simple.  They have less to break.  You have to remove them and disassemble them to make any variety of modification, and you have to modify them anytime you make a drastic change to the engine or environment.

EFI is complex.  It has a lot of things that break.  You only make adjustments for engine modifications and you adjust it by plugging the system into your laptop and clicking the left mouse button a couple times.

yeah, why f%$k with things?  the carbs work fine and are easier to work on

hahaha when was the last time you had to rejet your car, Terry?

I've only owned one car......it was a volvo with a turbo......I blew the engine up   good point, kinda, I just don't see the point of it on the GS....it's not like working on the little Mik's is hard

no doing carb work isn't hard...it's actually a lot easier to disassemble a carb than an EFI setup. But compare how often either need to be disassembled.

I think EFI would make the GS perfect...but only an adaptive setup.  Something that isn't single-map based but can adjust to different environments and modifications with an O2 setup would be perfect.

Nah.  The only carb I ever had to tear down twice was a Bendix PR-58.  They work better when you put all the parts back.   

Actually, I prefer propane carbs.  The Impco carb and vaporiser on my '72 Clark 8,000lb forklift is just about the only thing I haven't had to tear into.  Been on there since '72, not a single problem.

What makes a carburetor "difficult" that that working on one requires patience, attention to detail, and careful workmanship, much like an aircraft instrument or a fine watch.  Properly serviced, carburetors are at least as reliable as the best EFI system and more robust to boot.  It wasn't until a few years ago that an electronic fuel injection system was type-certified approved by the FAA for use on aircraft.

Don't get me wrong...I'm not saying EFI can outperform carburetors...or vice versa.  A properly tuned EFI system will work as well as a carburetor, and a properly tuned carburetor will perform every bit as well as an EFI system.

The difference is in the tinkering.  For example, anytime I took my FZ down to Houston to cruise with my brother, I had to up my jets just to run ok there.  Too big an environmental change.  Jetted properly to either site and the bike would run at the opposite.  My TL, on the other hand, had an air density sensor so she ran flawlessly all over the place.  I just had to tune for my modifications...never the environment like with a carb.

A carb adds hands on difficulty, but offers superior reliability due to it's simple nature.  An EFI system adds difficulty and takes away reliability through it's complexity, but it's hands-on operation requires only trigger-finger skill.

*ahem* from my basic training 1Sgt: 'You don't fire a f%$king weapon unless you can strip it, clean it and fix it'

I can agree with that.

So, Terry, how often you field strip and clean that turbobrick?

I have seen mega squirts done using a 2.2 caviler throttle body,and injectors.The freaking fuel pump was massive.The size of a soda can and externally mounted.You also have to deal with water temp sensor,which can be put in an oil galley,and oxygen sensor.Throttle body contains the other sensors.Don't forget you'll have to have a lap top to set fuel parameters.

$6500...for a new bike. 

Actually mak.....when I first bought it it had a bad head gasket and the turbo was hanging half off.  I rebuilt it, with a little help from a neighbor  and i'm not the one who brought up the trigger finger issue

yeah but then compare yourself to the next brick owner.  i'm pretty intimate with both carb and efi systems but the average joe isn't.  if operating something required intimate knowledge of how it works and how to maintain it was a requirement, we'd either have no operators or no mechanics.

My point: If you have the aptitude to convert a GS to EFI, you can maintain a carb easily so why drop the funds   500....you can buy a fuckin GS for that

I would do it for someone else...like Kalee's bike I wouldn't mind be EFI...or for something that's going to see heavy modification.  For an otherwise stock GS...no, no point.
