1123cc Big Bore Piston Kit for 1000DS

[J5]

I'm back in the saddle again. Nothing much to report.  The bike feels very strong. I'm keeping the revs to a max of 5-6K RPMs. I'll put several hundred miles on it before we wring it's neck on the dyno.

the dyno is a perfect place for running in

I'll be honest, I'm looking forward to comparing the performance of your motor to Ungehuer's.
I don't care that they have different mods, and are using different fuel on different continents on different dynos under different conditions.

Like the baddie in the Eastwood film said, "I've just got to know".

Yeah, me too.  I've been following this thread for 12 pages and still nothing!  Common man,  break that thing in
and put it on the dyno.  You've built enough suspense, it is now time for the big dramatic finish.

QUITE LOLLYGAGGING AROUND

If the pistons were matched to Nikasil coated cylinders (or similar) then all it needs is a good long ride of a tankfull of gas without ever turning it off at progerssivly higher RPM and throttle openings....

Get back home, pull the drain plug and inspect oil, refill....

PUT IT ON DYNO.......

Hey Travman

How's that bike going?

[TAftonomos]

I just boxed my "motor" up to send to Donnie.

Going with a similar combo
-big bore
-headwork
-cams
-crank lightened
-rods

I decided instead of spending a ton of money with Ducati Kaemna on lightweight parts, it might be a good idea to have the bike running and driving first.  I can always cut off the back of the frame and make a cool tank later....

[junior varsity]

wait, aren't you in ATL?

[TAftonomos]

yup. 

I know who is here

I'm choosing to send my motor to Donnie.

Since Christmas is coming would you promise to share the power outcome with us via a dyno reading when it's finished? Unlike some who are holding out on us.

This would enrich the two-valve sub 100 hp lives of many of us.

Sorry Koko, I have nothing to show so far.  All I can say is someday it will be put on the Dyno. I'm pretty sure it will happen this winter.  I do have a few hundred miles on it now and I'm no longer worrying about where I shift.  It is very fast. I not sure how to quantify how much faster since it has been many months since this bike was at its stock displacement.  It's quick and brutal enough that it scares me a little on the smaller country roads.  I don't remember that before the work was done.

Theo's future 1123 should generate more max horsepower than mine. Mine still has the stock cams and rods. Also my crank was not significantly lightened.

[koko64]

I'm just green with envy Travman.

[TAftonomos]

Only reason why I'm going with rods and crank work now is the condition (questionable) of the bottom end. 

I've been looking for a 1000$ or less DS motor for a few weeks now, and can't find anything.  Hence, it's time to just get the bottom end done and go from there.

I may "prove the concept" before dumping in money for the heads/cams.  The more I'm thinking about it, just getting it to run may be a challange on injection.  No one close that tunes the 5.9 ecu.  May try and start it on a stock ds1000 ecu and add a PC.

Subject change..... it's now got a 749R shock/linkage and triple tree on it
