1100 Evo Vs 1100 DS.

[koko64]

Asking the knowledgable here.
What are the differences? Including MTS and HM models as well as the Monsters. I understand the 1100 MTS only came as DS models, but were wet clutch.
Cheers.

Mts and hm are narrow cases

[koko64]

All 1100 Hypers are dry clutch, whether Evo or DS, so the only dry clutch Evo motor is in the Hyper1100Evo.

I know the intake ports are bigger on the evo engine. I have heard the cams are the 1100 ds dp spec but do not know 100% on that

asaik ( which isnt much)

the 1100DS motor is dry clutch in most cases, and is nothing more than a 1000 motor with bigger piston.

the 1100EVO motor is single spark, is only dry clutch in the HM, otherwise wet clutch, has lighter flywheel and timing gear. the timing sensor is also located at a diff location and is a different size as well. the cases are also made using a new vaccum method that makes it lighter and thinner( there is a significant weight savings on the EVO motor cases compared to the 1100).

It also has a different cam profile then the 1100DS does.

it also has composite material valve covers instead of aluminum.

LOL, "isn't much" .  Says the guy who fit an 1100evo motor in an s2r.

You probably know an order of magnitude more than the service personnel at my local dealership.

im just a wrench monkey slapping shit together lol
i dont know shit.

I don't think i ever told the whole story of how i came about that motor, but basically, i bought it off a drunk on the street without knowing if it was going to fit for not. He was heavily heavily drunk. The thing was sitting inside his jetski which was in a small ass garage at his mothers place in brooklyn. I paid a song for it and it wasnt even ready for its 600 mile service, ended up fitting pretty nicely.

According to the bikeboy cam chart, Evo cams have more lift and duration than the DS cams. The DP cams appear similar but a little different.

Pretty tough jetski motor.

1100 Evo has just two spark plugs.

Whereas 1100 Dual Spark does not.

Weird .

I think the DS with its heavier flywheel and innards will be smoother and easier to roll along at lower speeds is my guess. The light internals of the Evo, based on my riding experience of my Hyper (assuming the internals are lightened like the Evo M1100), are almost too much of a good thing. You can feel how instantly it spins up with corresponding engine braking. Certainly potentially very on/off riding requiring good throttle control at lower speeds. Great when going for it, but not so good in slow traffic. It leaves a narrow tuning margin for 1/4 and less throttle.

.... you ride my DS Monster...

I'll ride your Evo Hyper...

and then we'll both know  



Or at least have an informed opinion.



all care, no responsibility

Sooo...

HM1100 engine is not the same as M1100 engine?

DS or Evo ??

[koko64]

Good plan. We can conduct a vigorous testing regime.

The rear section of the cases comes between frame supports for a sturdy structure iirc according to Speeddog and Duckstew posts about frame and motor compatibilty. They know the details.
The swingarm pivot is encapsulated within the frame structure so the cases at the pivot are narrow enough to fit. It must give extra strength like the SBKs which is also useful for multi stradas.

I totally concur. The EVO motor picks up like a BEAST. I mean that is trying to go into the future. Mine is fully tuned out and with a 14/51 gearing (-1 front and +1 rear) its still pretty twitchy low speed.

When I had my DR650, the rideability of the monster in urban traffic really evident and riding them back to back revealed how unpleasant of a ride the monster really is.

a heavier flywheel would soften the hit, but the DS1000 motor case covers is narrower, so i dont think the flywheel would swap over.

Its not the fastest bike out there, but it sure wants to get ridden like it is.
