DIY Air Cooled Hyperstrada?

[koko64]

I'll come out on this one. Been thinking about building an adventure/touring bike using the HM1100DS as a platform.
My Hyper Evo is evil in the best way and I dont want to neuter it to the tune of 10-15hp by fitting a big tank and losing its intake mods. A CCW tank is an excellent idea for my proposed build, but not for my evil Evo as I have it set up. It is a light crank, race style motor that performs magnificently in its role and I wouldnt change a thing. Anything in the cases that spins has been put on a lathe or drilled at the factory, add to that higher comp, bigger ports, hotter cams and different combustion chambers giving the Evo a wonderfully aggressive character. My sportbikes mates struggle to keep up. Despite appearances the only thing the Evo and DS motors have in common are bore and stroke and valve sizes.
I would buy a Cagiva Gran Canyon if I found one but that aint gonna happen unless I move into Speeddog's neighbourhood.

A two valved, aircooled, lazy , heavy crank motor with an actual flywheel, fuel range, luggage capacity and the right ergos for me and the GLW is in my thoughts. We have tested the MTS1100, ST2, E900, E750, 900SS, 750 Bifaro etc and the Hyper suits us two up. So why not a DS 1100 Hyper with big CCW tank and DP luggage, screen and dual sport tyres? It will be down 10-15 hp on my tuned Evo but have a smoother mild cam motor with creamy midrange power. I have tested and tuned the DS1100 motor for others and it lopes along nicely. My Evo doesnt lope, it charges.

How does this recipe sound?
CCW tank kit,
DP luggage kit (got some bags and rear bracket for case),
Fabbri touring screen,
TKC 70 tyres,
Sargant Seat (got one customized for pillion riding),
Maybe slightly higher bars
PCV and optimiser tuned to the CCW pods kit,
Leave the stock exhaust CAT but maybe slip ons to not ness with luggage,
If needed a heavier flywheel from an early ST2 ( gosh they're smooth),
GPS mount,
Maybe some pod socks.
What else you reckon?

I have discussed this with others and what makes the Hyper DS a good platform are the MTS style motor, light weight and dirt bike ergos. Stepped seats are out because my pillion in a million cant sit "up there", so the MTS and ST2, etc are out. Water cooled 4 valvers are out and the Hyperstrada 821 and 939 are way too tall. I want two valve grunt and simplicity. E900s cost nearly twice that of an HM or MTS1100DS.

So I have outed myself here with this self indulgent plan. The same but two very different bikes.
The idea of selling my Hyper Evo and hotting up an M1100Evo has crossed my mind. Then I could find a HM1100DS to modify, but the HM1100Evo is a comfortable M1100Evo for old guys with old injuries. The Hyper Evo could in time also be my track bike as I have noticed my Gixxer now makes me suffer on track days. Old sporting injuries have caught up with me and I need a week to recover from a day at my favorite
track. Some spare Hyper wheels with slicks, hmmm.

Anyone know of a GC I can buy and send to Jenny Craig?

I like the idea.  Just out of curiosity, since power output is not the concern, why the pods?

[koko64]

In order to fit the 22L CCW tank, the kit includes small pod filters that look like they clamp straight onto the throttle bodies with no V stacks or airbox trumpets. This allows airbox removal as the airbox is displaced by extra fuel tank volume.  The little pods look like they dont have much tuning potential and if they maintain close to stock power I will be happy. It is not a criticism just an acceptance of opportunity cost in order to gain 10 more litres.

Since the oem airbox is mainly a baffle I dont thank the little pods will hurt too much.

Got it.

It's always annoyed me how the big trailies all weigh over 500 pounds wet and that they carry the weight so high. Such tall, heavy bikes with a high C of G are quite daunting for short arses like myself. I reckon the Hyper with CCW tank solves that issue as the bikes are so light and the fuel load is distributed along the length of the bike under the rider and centralized within the frame perimeter. Pretty cool.

Why not just modify an older 2V multistrada?

[koko64]

Maybe if I found a crashed one, but I would have to modify the rear frame to get a more level seating position for rider and passenger. I would ditch the front fairing and fit all the electrics in the airbox cavity and run smaller beast stacks. You go through extra cost re-registering a repairable write off in my state. A modified Corbin one piece seat could help too. The mass centralization of the CCW tank is very good. Much depends on a good score at the auctions.
The Hyper ergos suit me and my pillion in a million.
I have given this long and careful thought and looked at many bikes for ideas but it really helps to get different perspectives from the devotees here.
