I got the GSXR muffler for $50, the rest was Jesse's pipe kit, DynoJet kit, carb bowl screws, adjustable fuel screw, shipping, etc.

I think it was money well spent!

The hole in the slide on the KTM is twice the size of the DR one.
I got 80,000km with no slide wear with 2 DR sized holes.

Thanks to 996DL for this clarification.
The spacer mod is to keep the needle straight. No other reason.
The needle jet will last much longer if this mod is done but you have to allow for the thickness of the spacer with your clip setting. 4th from top = top with spacer.

How bad was your weld? No 2 DR's have the same weld or amount of restriction. My header had 60% more surface area after grinding the weld and no turbulence.

It's great isn't it

I couldn't imagine how a pumper could improve on it either.

After 3 1/2 years of DynoJet kitted and dyno tuned bliss I tried one.

It does...

OK, it's official ... I am a rookie I rode today with some pretty experienced guys who took the dr places where I seriously battled to follow.

Put simply Jenx was too slow and too nervous. But those guys I rode with were so patient!

I took a tumble early on in the ride (some fairly gnarly single track) and dented the tank as well scratched the light cowling Oh and slightly sprained left ankle. Not cool. But I learnt a lot today. In fact a sh-tload.

So IMS tank, here I come!

I should have paid more attention in geography!

Jesse's justification for the spacer mod is based on the premise that the circlip sits on the top of the shelf. After examining the parts and reviewing MX_Robs carb needle images I'm not convinced that's how the DynoJet folks intended it to be. With the clip on the very bottom of the slide the needle sat square and was pointed straight down. And it also appeared to have a good clean path of travel in the jet tube when I cycled the slide before I put the carb back on the bike.

I suppose there must be something more to be gained with a pumper carb if you folks are all progressing to that after riding the tweaked BST-40.

Maybe I'll go there myself after I burn out the needle/slide/jet/diaphram stuff on the CV carb But seriously, I'm going to enjoy this level of improvement for awhile before I get a pumper carb.

And the DR650 can be a real money pit if you want to get carried away. There's always a point of diminishing returns with these things.

I may be looking at the successor to the DR650 before I feel the need to do much more to my bike.

Hey Ed-B, cool name! The DR can be a money pit but so worth it! Just some body & suspension mods for me.

Two thousand six hundred eighty four PAGES... wow!
(EDIT - hahaha... in the time it takes me to compose the post, we go to 268FIVE.)

So I'm finally pulling out the big guns for DR help and coming to ADV.

Bike croaked awhile back, no spark. Traced it to a bad pickup coil and spliced in a new one.


Time passes as I wait for a new gasket, finally got it all buttoned up on Friday night. Unfortunately, the darned thing still doesn't work. I now have spark, and it will run very briefly, then it dies. Based on Thumpertalk threads I've tried flipping the leads on the pickup coil but still no luck. So, I ohmed out the CDI with my non-Suzuki approved voltmeter...



Having never done this I'm not entirely sure what to expect, but the majority of the readings came out in range, EXCEPT for the following...

Column #11 was apparently an open circuit - no readings.
Column #9 was consistently low, around 30 kOhm.
Couldn't get a good reading on Column #10... to much inductance or capacitance in there or something.
Rows #9 and #10 were consistently high, around 100 kOhm.

So, does this mean the CDI is croaked? Are there better ways to troubleshoot this if the pickup and generator coils appear to be alive?

Next, the darned CDI is over $500 new Anybody got one for a 2006 laying around?

Going to Big Bend in a few weeks, gotta get this thing workin!

A parting picture of my hoss...

Alright, so inspired by nicomama's DRZ400 with the round Baja Designs headlight I decided to pick one up for the DR650. With the little headlight fairing gone I'm gonig to have to drop the windshield a few inches:



and a side view:


I'm going to have to go in there and reroute / wrap up all the wires as well.

My bike came with the scorpion s/t tires on it.
Very good street tires, they are radials, good grip, long life, quiet.

Hard to see needing better brakes off the track, maybe try better pads?

I ride every day around 50km through Sydney in all weather conditions (I don't own a car). I've got 5600 kms on it now and it's still in "stock" form - Ventura rack and bag proved to be amazingly practical.
I want to change the rear & front tyre.

Questions:

1. What is the best road tyre combination for the DR? I'm especially concerned about good grip in wet weather/rain and durability. Are the
Pirellis MT90 Scorpion S/T as good as everyone says?

2. What would you install (in order of priority and brand ) in order to improve front and rear brake performance (no conversion to 320mm supermoto rotor & tyres allowed )?

Thank you for your suggestions.

Since I lost two sets of bar end weights, I quit replacing them. They would have been in the way for the 'barkbusters' anyway. I've never felt the DR vibrate bad enough to care about. Stock bars are rubber mounted, so are the foot pegs. Make sure all your nutz-n-boltz are tight, especially the motormounts. The Zuki engineers did a real good job with the gear driven countershaft balancer.

Not for me. My DR runs perfectly at 5800ft and up, snorkle out. I have a V-Max if I want speed.

Edit: I think there's a thread on posting pics, but I don't know where or how. Oops, welcome to the site.

Sounds like the needle jet is leaking (under float), letting fuel past. It then migrates into the cylinder as Carb overflows into air box. Dangerous.

Anytime the bike sits, fuel is likely flowing into the cylinder. I would not run it until you stop the flow. Sometimes just rapping on the Carb Bowl will stop the leak. Try it. Good luck, be careful, could burn your house down
and for sure will ruin bearings if run with gas in oil.

Ride the Ninja!
OOPS. Too late.






I started out in the C group. Ran one session in the morning on the DR. Not bad. Got bumped up to B and ran the piss out of the ZX for a couple sessions. Then on the last session I jumped back on the DR. Being that is was hot as hell and late in the day there were only 3 of us out there. I lapped them both on the DR.

Actually it's a huge difference if you can even fathom that. There is no comparison in low end smoothness and throttle response. The vacuum carb's slide jumps up and down causing serious huck a buck at lower RPM's. Just try sticking your bike in 5th gear below 40 MPH and take a listen. Sounds great doesn't it?

Quote:

The GSXR muffler is a top quality piece, and that Two Brothers pipe kit that Jesse offers is equally nice. Perhaps the performance exhausts make a a better dyno chart, but what are we talking here, really?
FMF would love to have a dyno chart like the GSXR system produces. You are not giving up a thing except the tiniest bit of nearly useless overun running the GSXR system. And torque, which is really the DR650's forte, is far better. No, be proud you have the best exhaust system on your bike regardless of what you had to pay for it.

Stick this in your FMF-Q2 "performance pipe" and smoke it..... And don't even get me going on oversized header pipes like the FMF "Power Buster" a fitting name. Might be useful on a cammed up DRZ... totally worthless on a DR650. Yeah, I have the dyno charts.
