749 Variations With DP Power Kit

The for model year ’04 is a bit to last years. It has the hottest of any Testastretta model (see the cam report), bigger valves, compression and a lighter crank. The non 749S — the 749Dark and 749 run the engine as the ’03 749 and 749S.

I got to dyno more than one of the 749S so far, but as far as I can tell the take away performance for of the rev range without really anything back. Pity.

But, I have only one ’04 and two ’03 models so so it’s not much of a sample. As goes on I’ll update report.

To some curves. up is a ’03 model, std and with DP power kit. The cheap Green is all std, red is power kit No air/fuel as the traces look a bit off to me it can be hard to get a good trace the std mufflers on these things finding.

Not sure why it loses power in the but that’s what I got. smooth, flat curve

Next another ’03 with the same power The main focus of these are the air/fuel curves. The asymmetrical DP have no x-over or balance between the exhaust for each so you can just stick the probe the muffler and go from there. gives a very clear of what each cylinder is And, for people who have to such equipment and experience as Performance do, the result is fairly

Lots of variation between and in overall fuelling. Really me actually. They have all the stuff and this is what do. It’ll be interesting to see how much they ride with a mapped ECU.

Duane currently has one of our customer’s with this exhaust for mapping testing/development with his U59 This graph shows and air/fuel — red is vertical green is horizontal.

The variation in is shown with torque in the graph. Both these are after cam timing with the ’04 ECU, and are vertical in red and horizontal cylinder in green.

is the first bike all std. Red is bike with the DP power Blue is the second bike the DP power kit. The runs power kit fitted (red and are both quite consistant so it appear they are quite Yellow is the third bike 749S) with the correct DP power kit.

You can see how the ’04 model trails the pretty much all through the RPM How they feel side by is another thing though. we’ll get a feel for as we have two who own one of each.
