1100 Evo Vs 1100 DS.

[koko64]

Someone mentioned that the Evo has improved cooling. Did the factory go back to oil cooled cylinder barrels?

Ung, when we swap bikes, we can each write our respective impressions here. Gotta organize that run.

For a Monster there are only two Ducati 1100 engine versions around that have the correct swingarmssetup.
M1100DS 2009 - 2010
M1100 EVO 2011 - 2013
Both of them share the newer Vacural tech casing and Siemens ECU.
M1100DS have dry clutch
M1100 EVO have wet clutch with a slipper function.
Special cams that are inbetween the old stock and DP,
Lighter flywheel and alternator.
New head with better cooling and single sparkplug.
Higher compression with new piston. Lighter gearbox.

The other Ducati 1100 engines around do not have the correct swingarmssetup.
HYM1100DS, HYM1100EVO - all dry clutch and MTS1100DS - wet clutch

But there are other alternatives.
M1000, S2R1000, 1000SS, - all dry clutch
Sport Classic - early dry clutch later wet clutch
GT1000 - wet clutch
they all have the correct swingarmssetup
and all you need to add is a pair of 1100 cylinders with pistons :-)
Note that I would not recommend to try to run these with Siemens ECU since it would require a
one-off timimg gear to be made.

MTS1000 - early dry clutch later wet clutch do not have the correct swingarmssetup.

All engines 1000/1100 have the same gearbox ratio, primary drive ratio, valve size, TB size.

Summary of things to watch out for when you change the engine on  a Monster

M696 M796 bike Siemens ECU
M1100DS / EVO engine
Just minor issue such as header and twin spark ignition coil

Monster "ST" -02 -->  Marelli 59M / 5AM ECU
M1100DS / EVO engine
Change timing gear, front valve cover to one with temp sensor.

Monster "888" -00 -- 01 Marelli 15M ECU
M1100DS / EVO engine
Change timing gear, front valve cover to one with temp sensor and the  spacer behind the front sprocket. (5mm shorter)

M696 M796 bike Siemens ECU
M1000 S2R1000 1000SS Sport Classic GT1000 engine
Major issue since the engine do not have the timing sensor in the engine casing. So a one-off timing gear will have to be fabricated. Engine temp sensor will also have to be solved.

Monster "ST" -02 -->  Marelli 59M / 5AM ECU
M1000 S2R1000 1000SS Sport Classic GT1000 engine
Just minor issue such as header and twin spark ignition coil

Monster "888" -00 -- 01 Marelli 15M ECU
M1000 S2R1000 1000SS Sport Classic GT1000 engine
Just minor issue such as header and twin spark ignition coil and the  spacer behind the front sprocket. (5mm shorter)

Note that the 1000SS engine have the shorter spacer behind the front sprocket.

No it is only the head that have improved oil cooling. The head even have "fins" inside where the cam is, on top of the combustion chamber.

Thanks hn. Cheers.

Some useful info there from hn 

Ung, when we swap bikes, we can each write our respective impressions here. Gotta organize that run.

Looking forward to it   

Nice weather this weekend, eh    I'm gonna go  tomorrow while everybody else is watching the GF.  Roads to myself I'll have

Got to ride an MTS1100 DS this week and it really compared differently to my Hyper Evo.

The heavier internals made the engine response smoother and gentle in comparison to the Evo motor in my Hyper. You can really feel the difference in flywheel weight making the DS motor more civilized at low speeds. While the MTS builds speed in a predictable way to reach a very strong midrange, the Evo motored Hyper explodes off the mark quite savagely if you have poor throttle control. Not surprising as it also has lightening holes on all the timing and primary gears.

I need to mention that the MTS was pretty stock with a Staintune exhaust from the cat back to the mufflers. It was very smooth with no surging so I guess it had a reflash too. It is a heavier bike than the feather weight Hyper, but quite light for a touring machine.

A good comparison will be Ungs M1100S DS with more similar mods.

Been talking to He Man who put an 1100Evo motor in his S2R. He put it in a nutshell when he likened the DS and Evo to "enduro" and "MX" versions of the same motor.

The problem I have with my EVO motor is that it pulls so hard off the bottom end that you expect this beastly powerband throughout.

You're unfortunately let down with a power fizzle out at higher revs.

Until I got used to it, I kept banging off the limiter expecting more. It doesn't help that the stupid dash goes farther than the redline (by 3k rpm). Its like the exact opposite of the original oversquare 1099 superquadro motor.

I love my Hypers fierce motor. Mods that give 100+ hp/80+ ft/lbs torque make it an excellent street bike.
The vivid acceleration means you can street ride with buddies on SBK's and keep up. Want to cruise, then snick up two gears and run in the closed loop map.
You do learn throttle control however.
