I'm still snowed in so I can't go out and do my "seat of the pants dyno" ride I usually do after work like this and the suspense is killing me!
According to these graphs: (Procycle, I hope you don't mind, if you do just PM me and I'll clean up the post)



And



You should be seeing around 36 hp and 32 ft/lbs. when I uncorked my dr, and jetted it properly, (stock exhaust, cut-top air box, KNN filter) it felt like it ran crisper with more low end power. When I did the carb upgrade, that was the most noticeable increase in pep. It almost has that fuel injection, instant power feel. I recently did the hayabusa muffler upgrade, and I haven't been able to ride enough to pin point my jetting properly, so I can't comment on how much different that feels. The exhaust note is much better, I can tell you that!

Thanks planeman! If the base line is an uncorked bike I wonder what the bone stock, off the show room floor numbers are in comparison?

just a quick question about those torque/hp graphs.

Were the exhaust, airbox and carbs (not jetting) the same for each level of modification?

What pipes and carb were used?


The torque # on the 780 kit is making me drool.

Bone stock peaked around 32-33 hp.
Individual DRs vary quite a bit. There is one local 'uncorked' bike that posted just over 39. (cut airbox, Q4, jet kit).

Buh.... so this shop said I need new keys, new battery, they want 1200 to get it running again from the fried wiring harness. They couldn't tell me why it went up in smoke.

Picked up this bike about 2 years ago and absolutely love it. I'm a photographer and use it to
go into the Everglades here in Florida. I have the Pelican case on the back for my camera equipment and it has
worked out great.

I took out the snorkel, did the needle shim and the mixture screw...could not believe how much better it ran after these
simple mods.

Here's a pic from one of my rides into the Everglades




Here's a couple of the pics I got of the Endangered Florida Panther during my Everglades ride..

Many thanks.

I am still running stock exhaust. The lighter can was on my to-do list and this is just one more reason to do it sooner than later :)

The 780 kit is BIG fun.

I bet it is,I was wondering how long a DR650 runs with 20 more HP then stock? Has anybody ran one very long?

The DR650 motor is pretty under stressed, no? ... my guess is the bottom end can handle it OK. The Oil cooler being a big plus for handling the extra heat from 20 more HP.

My concern would be the trans ... and 3rd gear specifically.

Probably be fine if not abused.
Too few examples out there to get much feed back.

No sense making a big production out of an easy task...

Are you using the stock tank? My IMS goes down pretty far. I can barely see my Carb without taking the other stuff off.

That was my first concern. With all that torque, you could always go from 2nd right to 4th.

As to abuse, "probably fine if not abused" why bother then. abuse it stock for the same effect as a babied 780.

Yeouch!
I would buy a used harness (eBay, etc?) and change it yourself.
No need to get new keys that I can think of since the ignition wires plug into the harness.
Even if the wires connected to the ignition burned you should have enough to splice in new.
I know very little about wiring but replacing the complete harness with a new (used) harness is easy if you just do as suggested to unclip and reclip one at a time.
I am never happy with any work a shop does so I end up doing my own work though.

Just my 2c
