I recently bought a '98 GSXR750. It was built 1/98 making me believe it should be a fuel injected unit? Previous owner bought it a while ago thinking it was injected til he pulled the tank off and had a closer look.
My question is, do you believe this "could" be the original engine, and how can i find out for sure?
The engine seems like a "factory" fitment, no excess wiring etc. But what puts a hindering on my suspicions is that the previous owner also said it came to him with fuel injected stickers on the fairings.
Does anyone have any thoughts or ideas on the best way i can clarify this issue?
shouldn't the engine id number be matched to the frame vin? i always assumed that 98 on was fi for the 750. maybe at one time someone blew up the fi engine and it was cheaper to swap in a carbed one. you never know. people do silly things lol
thanks for the reply TT750. that was my assumption also. How exactly are the VIN and engine numbers matched up? And where is the engine number located?
I will post up both numbers and the wealth of knowledge on this forum may be able to give me the answer i'm looking for!
Engine number is at the rear of the motor. Should be able to see it in front of the rear shock. Also, spare parts people at a Suzuki dealer should be able to tell you exactly what it is by using your frame number.
hm. i have a 98 750 and the wiring harness that plugs into my ecu looks much different. what does it say on the title? and on the rear of the gas tank is there a hose comming out?
That is a carbed ECU!
I have never seen a 98 that was not factory fuel injected.
Very unlikely you got a left over with carbs instead of F.I.
More likely you got a bike that had a transplant.
Look for signs that the motor has been removed/replaced.
Take a hard look at the surrounding hardware for marred bolt heads and alike. You should see some evidence of previous work done.
With a carbed motor must also come the accompanying harness. Look for signs of a retro fit there as well.
Usually...Someone will install what ever they can find when the old motor goes bad. Carbed in F.I./F.I. in carbed/600 in a 750 and vice versa.
Not much to see from where i am sitting so the question you are asking is quite difficult to answer.
Is it possible carbs were fitted to an F.I motor...YES! More likely though that the entire motor was changed because the previous one went bad.
Well...After changing hands 3 times it appears some work has been done.
If you have yourself a clean/good running srad, the point you seek to prove becomes a moot one. I understand your curiosity though. I'm old school myself and actually PREFER a good running carb set up over F.I. most any day. Easier to diagnose and easier to service if need be.
As long as you have a 750 power plant I would not get too hung up over the original engine issue. I know of folks who purchased 750 srads only to find out they had 600 motors transplanted in them and have looked at several over the years myself. Now THAT would be a bone of contention if ever there was one!
To be honest it doesn't phase me, I love the bike and I think with the future mods I have planned ( cam's etc ) it will be much more user friendly.
It was merely a nagging question in my mind, if it was original or transplant, since the conversion was so well done. I checked on the engine and it has 749 cm3 so it must be the 750 thankfully.
I'm going to do a compression test tomorrow just to confirm there's no issues then look into cam's and a few other things.
Though I was really of little help, you are quite welcome.
