the DR650 thread

Getting close to 2-1/2 years now. No problems whatsoever. The thing is, 98% of the time you aren't using any of the additional 20 HP. It sure is handy when I want to pass a truck uphill.

[opium89]

Parts finally arrived so....Pine-Sol dip, new main jet, new pilot jet, and new KTM needle and the hesitation off idle is now completely gone. Only issue I am having now is some pretty obnoxious decel popping at > 1/4 throttle. What I mean by that is the decel pop is minimal to nada if I don't get on the throttle much. It's only on decel when really opening it up that the popping starts to get bad.

In an effort to remedy, I tried adjusting the fuel screw, seem to improve a bit the wider it's open, but still present no matter what. However, it does go away if I throw the choke wide open...

I set the KTM needle on slot 3, right in the middle, as this puts the spacer at the exact same location as the stock needle. I gotta say, these needles look nearly identical to me. Is anyone with me in suggesting that I try raising the needle up a slot and see what happens?

Almost there.....

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

I am gonna try it myself. I was trying to sell it and I was hoping the dealer could get it fixed quickly but 1300 is just too much.

Buy a kit, I'll help with the install, then ride it like normal so I can have a baseline for when I do the DR in my garage.

Ok, I get that this is apparently really necessary. I'm a complete noob, but I managed to successfully change my stock tank to an IMS, or so I thought... Seems to be fine except that when I put on the long vent tube on the gas cap, the engine doesn't stay idling for more than a few seconds. I take it off, make sure the other end of things is covered up, and my bike runs fine. So what's going on here? Should I purchase a shorter vented tube, or did I route some things up incorrectly?

I bought my TM40 about 10,000km ago and everything seems fine with it. But wondering Is there any preventative maintenance for the TM40's - apart from changing fuel filters etc??

I've never actually pulled one apart and don't really want to unless its necessary. I know I wouldn't have to with 10km on it but what about 20k 30k, etc

Sounds like you either didn't reconnect the vacuum hose on the petcock. There should be two hoses on it. or your vent hose is clogged. try blowing some compressed air through the vent hose.

Or when you want to tow a truck uphill...

re: Everglades

Ever have to run from an alligator??

re: 780/790

Jeff's been running his hard for ages (like he just said) and it's fine. Adding 20 hp to an almost-40-hp motor isn't that big of a deal. I ran my WRX at 400 hp (224 stock) for four years and it was still running strong when I demodded it to get rid of the payment (since I ride 99% of the time).

re: Fork Solution Kit

I FINALLY rode my DR today after last weekend's Fork Solution Kit installation... .47kg springs and Gold Valves. WOW, nice improvement!! All I could do was ride asphalt and an unusually smooth stretch of "what used to be a gravel road." But the few bumps I did hit were much better controlled than before. Hey, to whomever it was that bought my Intiminators -- get the stiffer springs! I think they'll work better with something better than the stock sponges.

It will pop on decel.
The BST carb has no coasting enrichener.

Tune for performance.

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..

This is exactly what my DR was purchased for, though as it turns out I love offroading just as much as photography. Very nice pictures..

My other one doesn't pop much at all. You don't think tweaking that needle a bit might help? I find it curious that it all but goes away when the choke is opened up.

That's because the choke is an enrichment circuit.

Almost there.....

Two Things:
Raise idle
Go back to stock muffler

Evil 3rd gear strikes again

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.
