Rusty Rocket:

That was in a test involving four DS motorcycles and there was no mention of any modifications so I do believe that is in stock form.

Are those figures for the DR650 or 96" Harleys?

MxRob on Thumpertalk got about 40HP with a Keihin, GSXR pipe and airbox mod IIRC.

Another guy from Sweden got 48RWHP with a pipe, header, ported head, high compression piston, airbox mod, webcam, ...?

Don't forget to take only with pinch of salt.

We have two local dyno tuners who have given figures 20% apart for the same bikes for a couple known riders who were on both due to tuning at one and dyno day the other.

Before/After charts are much nicer to take with lots of salt. And vinegar... mmm

I've got a spare webcam I can use but I can't find a USB port on my bike at all :(

That's why I go to the same dyno.

HP talk......or torque?

It seems that the whole thing with these bikes is the amount of torque that they make AND where they make it AND over the range that they make it ..... not horsepower. High horsepower numbers are relatively easy to get, and even easier to brag about, but they, real or imagined, aren't much use if they give you a usable range of 700 rpm at the very high end.
If all I wanted was horsepower I would put a 1500 crank in a Hayabusa and feed the bitch nitrous or put a hairdryer on it or both.
For what the DR6fiddy is made and generally enjoyed for, give me reliable, regular gas, low down grunt over a peaky screamer anyday.
Having said all that, it is kinda fun to squeeze more out of any internal combustion engine.

As long as we enjoy it, we should keep doing it.

You probably have the wrong model then. Only grind # 223 will fit:

+1. Being able to roll on the power, 2 gears too high and still power out of trouble in the rocks and roots is a bonus.

Got bit by the no fuel filter bug today!

Luckily I only got to the end of the driveway. IMS tank and FCR-MX carb, I hadn't 'found' the time to install an inline filter. Bike seemd a bit hard starting & sluggish, then stopped dead, wouldn't refire. Pushed it back to the garage, opened the bowl drain, nothing came out. Pulled the hose off the petcock, had plenty of flow. Off to the auto parts for a filter & some hose!
Fortunately there is just enough room to tip the FCR carb over and pull the bowl off. Blew air up through the float needle port & put it back together. Connected the fuel line & filter, opened the tap and had flow through the bowl drain. Bike runs great now.

Funny how you can find the time to fix what you didn't do right in the first place!

Another question. Is that an old roman road? Via Appia??
