I would think so too, especially if he's riding at any kind of altitude. He's going to want to be able to flow more air. Even here at sea-level, I noticed a difference with opening the airbox and exhaust to flow better, especially at higher RPMs.

Open the airbox (cut open or door removal), find an exhaust that flows well without sounding obnoxious, and tune the carb (stock or other). The choked-off stock engine will thank you. THEN go tearing into the engine to replace a piston and/or cam.

You may get better performance than stock with just the piston and cam, but it's not going to be optimal without being able to flow more fuel and air in and out.

I would recommend suspension changes before messing with the piston. Probably LED lights too.

Hope to see you out on the trail. I've done the rest of the mods and the piston is next on my list. Let us know how it goes should you proceed.

Ever try to push start a DR650 with ammo can panniers on gravel?

I managed to macgyver a jump from some guy's pickup truck by removing my battery and connecting it to his trailer light connector. There were vehicles at the trail head all from hunters who'd packed in for the week. Fortunately the guy didn't show up to find me stealing a jump off his truck.

I'd almost killed my battery this way a year or two ago but noticed the tail light on.
You sound like a candidate for a dual-battery setup. Carry a charged spare. You could also carry one of those solar panels that folds like a map.

Thanks much, jessepit I appreciate your response. I am glad you mentioned the smoother motor with the lighter piston. Sounds like I need to plan on a winter project. :-) Besides the power increase, smoother would be nice, vibration is the biggest complaint I have with the DR650. Actually it is my only dislike. My KLR250 at 330 cc and my SV650 are much smoother than the DR650. That said, if I was limited to one bike it would definitely be the DR650. It is just such a good all around bike.

I have the stage 1 cam in mine right now and it makes the motor much 'crisper' feeling to me, but does not add much power above low and mid range.

By the way did you run regular or premium gas in yours?

Suspension mods, Seat Concepts seat kit, different handlebars that suit me, different gearing, (several sets of gearing) stage one cam, Turbo City WS with Laminar lip, custom rear rack, Cortech TriBags, DRZ-S rear shock, Hi Intensity headlamp bulb, true 50 - 50 DOT tires, Waterproof GPS and a few other touches done. :-) Thousands of miles ridden. :-) Just want a little more oopmh on the highway with a quiet stock exhaust, had a GSXR1000 muf on and didn't like the noise.

Was mostly just poking fun although I was serious about suspension.

The high compression piston seems like a hell of a value and will be on my Christmas list.

After the few years of keeping up with this thread and modifying my own DR, I still enjoy seeing how each rider makes the bike their own. One of the strengths of the DR IMO, personalizing. A good common base with an endless list of outcomes supported heavily by the aftermarket and penny tech tinkering brains around the globe.

Lookin' good MeterPig..!

Is it possible that you have an electronic flasher module, like those designed to operate LEDs at a normal flash rate?
The flasher is whatever is stock. I put mini turn sigs on a couple years ago. The bulbs are 12v 23W. Everything worked for years, but all of a sudden none work but the dash indicator still flashes.

I'm headed to the garage to dig around in the harness.

That's just one setup. My DR will be in the next movie installment of Transformers

anyone still accumulating parts for a quick change rear gear and rubber setup:

http://www.ebay.com/itm/2003-Suzuki-...d12389&vxp=mtr

no affiliation with the seller.

I've finally got a complete spare rear wheel and second drive hub for my ADV and singletrack setups.

Question Aqualine + Brittania Comp + HDB?

I'm currently running an Aqualine Safari tank with a Britannia Composites fairing and Fat bars. I'd like to add a HDB set of hand guards with clamps, but I'm concerned about clearance between the tank and the ABS portion of the fairing. I'm already hitting the tank before I run out of steering lock.
Anyone running a similar setup? Successfully?

Stock Flasher Relay

In search of a DR650 stock flasher relay.. I gave away my stock unit to a member doing a RTW trip after I switched to LEDs, but I am in the process of returning my other DR650 back to stock so looking for this part. If you have one please let me know! PM me please :)

Thanks!
