2000 M900ie mods - HC pistons, big bore, or swap for 1100ds motor?

[Duck-Stew]

If the owner has a custom built shorty exhaust that he would want to keep...  It will require welding and such to get it to mate to the 1100 motor.

When cost comes into the equation (and it always does), and if it were my $ and my bike: I'd do drop-in high comp pistons and have the heads ported and such.  If it doesn't feel like enough 'uuumph' after that, I'd cut down the OE flywheel to something between stock and the AL flywheel.

I've run the JE drop-ins with pump gas and not had issues BTW.

Thanks Stu.  Good to know on the JE drop-ins and running pump gas.  What did you do with timing to accomplish that?  And was that on your '01 900ie?

My brother runs premium pump gas here with stock ignition and a PCIII with no issues. Its the carbed 900s that need retarded ignition and a more gradual ignition curve. I've not heard of anyone having issues with the 900ie .

Stu will know more.

With a light flywheel, light clutch and the top end mods you are planning, it will be an entertaining motor. My bro does second and third gear wheelies on his 01 900Sie.

You should probably get the hot cams from a 900Sie, just to seal the deal. I know a bloke with a set  haha sounds like it will be a sweet motor when finished!!

The injected bikes (with proper mapping) do tend to handle the increased compression better than the carbed bikes for the reason you mention above ( the timing).

The 1100 motor with the DP cams will *EAT* any 900 for breakfast, lunch & dinner.  Go for it if your wallet allows....

Same cams.

Absolutely, my Hyper Evo is quite vivid for a two valver.

Same cams.

whoops! all the better motor then!

Thanks for all the great input  Definitely consistent recommendations on mods for the 900ie.  Decisions, decisions!!  

The 1100s motor I'm also looking at is from 2007 and out of a Multistrada.  It has the DP race cams out of a Hypermotard.  Sounds great, but what performance do those cams add?   

I think the heads are otherwise stock.  With the hotter cams, any head mods recommended for the 1100s that would make a big impact?  Also available is a full Termi system and matching ECU.

What about flywheel mods for the 1100s?  Make it lighter?  By how much?

Thanks!

I have been working on an MTS1100. Didn't open up the timing case so don't know how fat the flywheel is or if it matches other models, but I'm guessing the same as M1100DS motors or possibly 1000DS motors, not sure. Check if it matches that of the 900ie with Nichols, never know your luck.
The motor is a wet clutch motor, but I don't know if any dry clutches carried over to the MTS1100s from the MTS1000. Stu, Eric or Speeddog should know.

From reports of the DP cams, yes they are a bonus for sure and are similar to the Evo cams.
I did a lot of test riding of this MTS and the motor is very smooth and civilized, indicative of heavier engine internals, unlike my Hyperactive Hyper Evo or M1100Evos which have everything lightened. I guess there is room to skim the flywheel.
Do you want an aggressive/sporty ride or more smooth and sedate? What I mean is that when I'm out with my mates who ride sportsbikes, I love my Evo motor, but when I take my wife on a date, or go up a dirt road, I would prefer the DS motor.

What's the 1100 motor going for?

[koko64]

Excited about this build. I want to do one but dont have the $$$.
Voyeurism 

[2001cromo]

I did this exact thing on my 2001 a few years ago and the motor has everything.
Bruce Meyers did the heads and Jay when he was still working for ECS built the motor.
It runs super smooth and clearly has more power. I'm likely going to part out the bike though as I no longer ride on the street.

You've gotten lots of good answers already, but maybe this may help.

Only thing that's not included in the above build sheet is the cams which were the DP cams which were exactly the same as the V2 torque grind cams. I think they were #230's or 203's.

Good dyno chart.

Thanks Cromo, that's awesome detail on the breakdown of the work/parts involved.  Super helpful
