Great read Phil, it was great to actually see all that work in the flesh. I emailed Racecomp to see if they still had some cams and got this reply

I have a set of cams, you
will need to use Daytona 955 headers
and open up the front of the airbox.
Cams are $2000 + GST
Option 2
is high comp 80mm big bore pistons, cams and H beam rods for $3600 + GST you will have a killer
engine with this option.


With the cams 150hp and the kit around 165hp

Bloody hell! That's great at least we have some options. The claimed HP is at the crank I'm assuming...? And what is GST? Probably a long shot to expect the 955 headers to bolt up to our 1050 mid pipes without more mods, anybody know?

Sorry Phil, didn't mean to 'jack your thread. But you know how hard it is to come about info on engine mods for these bikes.

No worries Bill & thanks Rob.

That sort of money probably extends beyond my desire to "maximize & optimize" this bike.

I've just returned from our Phillip Island GP. We covered about 3,000 km all up, including some pretty brutal unsealed roads that always ended up in twisty heaven. The bike performed absolutely beautifully. The only issues I had were very cold starts. It took 6 or so attempts to start her but no issue when warm. The torque when touring is amazing.

Unfortunately I did have a mishap about 300 km from home. We had viscous 35-40 knot crosswinds around Bungendore and I got hit by a huge gust just as I stopped at an intersection. I put my foot down on loose gravel but slipped and the bike was over in an instant. Scratched fairing, pannier & bits & pieces. Oh well. Put my claim in and let the insurance company sort it out.

Bill I'm a little curiuos about your attention to detail in the weight loss program for your Sprint. After all, you appear to have a Duc that would satisfy the lightweight sport-bike characterisrics you appear to covet for the Sprint.

GST = Goods and Services Tax in Australia this is 10%

Sorry about the tip over Phil, that sux! No mystery about the Duc - it's a race bike with a license plate and beats me up on the street. There's nothing like it but gets old. With a few key mods the Sprint does it all.

Edit: After giving this more thought, it was hopping on the Sprint after riding the lightweight Duc that made me want to cut some pork off the Sprint.

Sorry to hear about the fall over Phil, still rather that than a moving fall.

For sure.
Anyway I put my claim in, paid my excess and took it to the bike shop. It's all just unbolt and bolt back on, except for maybe some paint on the upper nose fairing. I hope I get a new lower fairing, not too keen on plastic welding & repaint.

Some observations on the bike after about 2,500 k travelled on the PI trip.

The fuel economy certainly has not sufferred. I was a little concerned about this after deleting the O2 sensor. At fuel stops (and there were many), I regularly re-fuelled less than my brother's 1200GS, always quite a bit less than the K1200S, neck & neck with the V-Strom 650 (poor bugger was red-lining quite a bit though...) and less than the Bonneville & 2 VTR100's.

The city cycle may be a different story though, but not excessive.

On the dyno, we did do a fair bit of work on the low (<10%) cruising throttle & ignition mapping and although it has plenty of torque down around 3k, it does sound a little rough until it climbs up past 4k. This may the bark of the Tridents though. By 5k its starting to spin very sweetly and the power surges from there all the way to the 9,700 red line.

I had no problem keeping up with K1200S on the more spirited sections and the torque really helped out of the corners. The PR3's are amazing!

The handling of the bike with all the swing arm bearings & links re-greased, new wheel & hub bearings was faultless. I put a little extra preload on the Ohlins shock as I packed the panniers, and preloaded the forks one full turn. This was pefect. We found some amazing twisty roads but often had to negotiate quite a bit of dirt and gravel to get there. Although the bike is filthy, it handled the unsealed stuff fine and the reward was always well worth the effort. Of course the V-Strom & GS had to wait a little....

I swear by the 6-pot Tokicos. The feel is fantastic and the braking effort is very tactile, not "woody" as some complain of. I think they are a definite improvement on the stock calipers and I never sufferred from the "sticky piston" syndrome.

Well I'm not the first to swear by the TB blue-printing and exhaust port matching. I've done 2 1050's now (including a friend's racing S3) and the gains are significant. If you've got the skill and the inclination, DO IT!!

Great report. Glad to hear mpg is still acceptable but what is your mpg now?

I was checking out your stock muffler mod and was wondering how much difference do you think there is between your stock mod muffler and the tridents, other than weight?
Can I get a copy of your current ECU map?

Great job and thanks for sharing. I hope my project comes close to what you have accomplished.

Philip
