How hard? M1100 motor into 696

[Raux]

I knew it had a Marelli ECU- but intention is running:

-696 Throttle Bodies
-696 Intake Manifolds
-Remapped 696 ECU with Power Commander and stock 696 harness...

i don't know... seems that trying to fit small block parts on a big block motor. like i said before maybe the throttle bodies would work, but mating the up with the intake plenums might not. plus the motor sensors from a MM motor compared to one from a Siemens?
how are you going to remap the ECU?  you would have to build a custom map to match the original MM map and get it to work on teh Siemens.

You are probably right- I think sticking with the 1100 engine is going to be the easiest...

An 1100 engine seems to be a little hard to come by these days, and some places are charging an outrageous amount for a used one... So We have now been throwing around the idea of an engine build.

So far the ideas are:

-M800/M796 Connecting Rods to basically make 696 engine a 796

-Lighten Flywheel

-Lighten crank

-Port/Polish heads

-Dual spark conversion

More info coming soon...

Put a diavel engine.... in a 696, and prepare to jump to warp speed.

need pistons too. different deck height

[2-Skinny]

What is the amt of difference in deck height?

stroke is 8.8mm longer so a 4.4 mm diff

[2-Skinny]

Hmmmm.... seems that won't be as easy as anticipated either...


Basic engine mods it is I guess...

Raux- you did some research on boring for 696 cylinders- I know they have to be re-coated in some anti-friction nonsense, but did you determine any meaningful amount that they can be increased reliably?  Maybe pistons from another bike would work in there- maybe 90-91mm high-comp or something...

Also, as an update to my research regarding re-flashing the 696 ecu with 1100 flash:

Anthony at Mota-Lab advised that, while the ECUs look the same from the outside, "the internals are different"... and thusly he could not flash the 696 with 1100 data because they are just different.

Although I suppose he would have the experience/knowledge, I don't know that I am 100% convinced.

Apparently there are hundreds of tables of data variables flashed to each ECU defining fuel and idle control for various conditions- he (Anthony) said that each of these would have to be reprogrammed individually.

Which, to me, means that it COULD be done if a flash existed.  All that would need to do would be to flash the 1100 data tables that are ALSO present on the 696 ECU onto that ECU...

Is it REXXER that develops the maps?  Perhaps if they were to be contacted they have a way to generate a map to this spec...

Also Raux- did you determine M800 crankshaft will NOT work?  Stroke is right, but the swingarm itself (per the fiche) looks quite different than those from 696/796...

different.  shock mount butcould be fabbed.
but notsure of exhaust routing

for the piston 796 could work.

I
didn't. look too much into bore due to costs of work herebut seemed 90/91 might be possible. based on the practice head bought

[2-Skinny]

Shit- I meant M800 crankshaft....

someone. bought mine and did as far as i know
