I'm lost.

Was doing some reading and somewhere I read that, 750 TBs are 88mm while 620TBs are 80mm, which made me look into my bike's specs: 45mm TBs vs 48mm... Huh?

Who's right and who's wrong? I'd like to install 750's TBs on my bike, once I get my hands on a DP ECU that is....  Cry

HELP!!! I might be in the wrong board, but, is a mod, ...  Huh?

I think all the fuel injected bikes use the same 45mm throttle bodies.  The injector size is prob different between models.  80mm is the bore measurement of the 620 cylinders while 88mm is the bore measurement of the 695/696/750/800 cylinders.

Yup, 88 is the cylinder bore, not throttle body.  That would be a friggin huge intake manifold.

I wonder how much else of the wiring is different.  Something tells me you won't be able to just drop in an ECU and the new throttle bodies without some other tuning.

FYI, the 696 uses a Siemens EFI system, not Marelli... I would love to check that out as it has the same HP as the S2R800 in a smaller engine.

The wiring is the same.

AFAIK, the throttle bodies are the same on 750 and 620.

At some point, they changed to a different type of TPS, I think it was the 695/800.

Perhaps some different injectors at some point too.

I know that the 900 used the same injectors as the 620. I would assume that the 750 did as well.

exact same or just same type?  they can be identical but have different part num = different sized valve.

I have a set of M750 TBs if you want them.

all 2v throttle bodies from ST2 to '06 sometime were the same apart from injectors, made by Weber.  ST2, 750SS and 900SS had green end feed IW031 (from memory) whereas 900M and all 620, 800 and 1000 motors use pico style injectors IWP043.  the throttle bodies will have different part number between models as the base idle setting will differ.  no reason to change between any of them.

'06 sometime they went to Bing brand throttle bodies with the balance screw facing rearward with a lock nut and impossible to get to with the airbox on.  don't know much more about them.  i've seen 620 and 800 with these.  695 may have a multy hole injector.
