Monster 1000 Engine compatibility

koko64 said: There's a long term plan; 1100 DS, DP cams, thin head gasket, split FCR 41s, ignitech, 100 hp.
Thats the way to go.
For a first gen Carbed Monster. M600, M750 & M900.
Parts needed:
Engine:
1000DS from M1000, 1000SS or Classic range. Not MTS.
1100DS or 1100 EVO from M1100. Not MTS or Hym.
Header
Use a M1000 DSS but the rear one needs a bit of "adjustment"
Or modify the M600 or M900 header.
Ignition coils with dual output

12mm engine mounting bolts hole
Just put a 12mm t=1mm copper pipe in the engine casing.

Thats about it

If you want to go the injection way you also need
- wiring harness
- ecu
- fuel pump you can use a external one and use the drain hole for the return fuel line
- TB  it is only the rubber between TB & airbox that is fouled by the frame crossmember
- instrument

/Henrik
M600 -96 with M1000DS engine DP cam, TPO Beast DP header running modified 15M ECU.
This winters upgrade 1078cc, Pistal HC & some head job.

Thanks Henrik

It sounds doable.
If there was a problem with the rear carb hitting the frame cross member I would relocate it if I was going to the trouble to replace the whole motor and the issues associated with that.

The other option (and this all depends on price), would be to get Brook Henry to fit big valves, ST2 or Vee Two cams and reconfigure the heads with raised ports and narrower included valve angle on a 944 motor. He has come out of retirement. In Oz DS motors are worth alot of money, even a 900 carbed motor is 3-4 grand.

Henrick:  How does the rear cylinder port on a M1000 header need any work?  Suspension clearance? 

[hnracing]

koko64: Just make sure you get the correct FCR41, one of each type and adjust the inlet so the bowl is in correct level.
Duck-Stew: The old type swingarm with a hoop gives you clearence issue with the rear header.
- The original M1000 DSS header needed the rear first part to be adjusted to clear the swingarm.
- The DP M1000 DSS header needed the spring mountings to be relocated to clear the swingarm.
And the front header to be shorted a bit at the rear end. To move everything forward.

Hi  All

The above can be done also on a later monster series as i undersetand or these motors are compatible only with the old Ms?

What year Monster are you thinking of swapping the 1000/11000 engine into?

[Duck-Stew]

Dude dug an 8 year old post out of a peaceful retirement to ask 1 question in someone else’s thread as his post #1 and then vanishes...   

[stopintime]

It took you almost half an hour to reply, so of course his attention span is greatly exceeded..... Young guy perhaps?

Must be.  Guessing this is dead in the water...

A 797 swapped with an 1100 motor might be cool.  All 821/1200 bikes require engine mounts to the heads, so that’s out.

Heck, you can BUY an 1100 Scrambler with a warranty. Why swap?

1100 Scrambler needs more breathing mods than is 'possible'.

I like the 797. It looks very basic and light. Ten plastic pieces removed + a proper engine = fast & fun.

Cylinder head & throttle body swap?  Could be good.  The new 1100 is quite restricted with that single TB.  I rode a Scrambler 800 and it felt SO weak compared to an S2R800.

[stopintime]

Maybe EURO5 problems are solved with only the one TB .....  Anyway: no reason why an 1100 Desert Sled shouldn't have a good engine

+1. Motor felt pretty soft when I rode one.

Anyone that have seen the Scrambler 1100 dual spark cylinder heads IRL?
Want to know if they are just the old ones or a version of the evo cylinder heads.
The spec of the cams seems to be softer then the standard 1000/1100 ds cams.
Note that the gearbox have the short ratio gears. So without the long 6th gear.
1=37/15 2=30/17 3=28/20 4=26/22 5=24/23 6=23/24
Maybe the intake could be used for carbs.

Close ratio box on an 1100 twin.
