DR650 NSU spring

DR650 NSU spring

To our dismay, the Neutral Sending Unit screws, plunger, and spring had fallen out on Duncan's DR650. We pulled the side covers off and used a void scope best we could to inspect the engine for damage and any sign of the missing pieces. Several attempts yielded nothing. Duncan suggested maybe screwing in the powerful magnetic drain plug he had gotten. Upon screwing it in I heard a click and pulled it back out. This is what we found.

Suzuki DR650 - left side engine cover removed

Suzuki DR650 - left side engine cover removed

Our thought was to see if we could see any debris from the other side of the engine.

As originally mentioned in a thread a long time ago, I decided to modify my '11 Kawasaki Ninja 1000. Beginning in the late fall of 2013 and continuing through spring of 2014 I replaced/modified/enhanced quite a bit :-). This was a terrific project that I had a lot of fun doing and I thought it might be fun to do a thread that lays out all of the modifications that were done, why they were done, what the end result was, and include some pictures. To start with here is the current measured performance and the list of major parts and modifications that were done. Performance- -HP (at the wheel): 147HP @ 11,500RPM; +100HP from 6,300RPM to cutoff -Torque: 85.5lb-ft @ 7,900RPM; +74lb-ft from 4,300RPM to 10,200RPM -Top Speed: redline limited, hits the limiter at GPS indicated 161MPH (on track) -0-60MPH: kind of a worthless stat on a litre bike as controlling wheelies and wheelspin artificially constrains performance at a hard launch (it'll still do it in less than 2.5 secs). 60-80MPH roll-on (passing speeds) is probably a better real-world metric...top gear 60-80 <2.5 secs. -Economy: believe it or not, it's better. I have the fueling mapped to have a leaner cruise when at low RPM and small throttle openings. On a recent trip I had no problem getting 45MPG or more cruising at 75-80MPH; on the track it's not as good :-). Modifications- Suspension: -(rear) Ohlins adjustable shock with remote, Ohlins track spring, custom valved and sprung to spec -(front) Traxxion Dynamics AK-20 Cartridges, Omni springs, custom valving, TD compression and rebound adjusters, pre-set sag, sprung to spec, Maxima Racing Fork Oil Brakes: -(rear) EBC HH pads, custom HEL stainless lines -(front) ZX10R master cylinder, Vesrah pads, custom Hel stainless lines, racing fluid Exhaust: -Akrapovic titanium 4-2-1 full system Engine: -PowerCommander V with Autotune module -Ivans Performance ECU, custom ecu load, Ivans airbox modification -Fuel Cutoff Eliminator and Servo Eliminator Driveline: -Barnett Kevlar Clutch plates, HD springs -RK 525 GXW Series Heavy Duty X'ring Chain -Sunstar 41T rear sprocket, 16T front sprocket Tires: -Bridgestone S20 Evo Hypersport -Dunlop RoadSmart2 Misc: -Lots and lots of little things from fluids to fasteners to nuts and bolts, tail tidy, LED lights, etc.

The transmission for my 1992 K100RS 16V was rebuilt by Tom Cutter of http://rubberchickenracinggarage.com/.

Now it's just a matter of dealing with a few odds and ends and I'll be able to begin the reassembly process.

Sooo.... After deciding to return Yang to its factory height I figured I would take advantage of the opportunity to tune things up, get the various adjustments done, and maybe do a little upgrade here and there. This involves going to a different rear spring, setting the ride height, the preload (set for loaded), and doing a couple of things with the front while it's disassembled. Removal and replacement of the rear shock assemble came first. Returning the DR to original ride height involved flipping the spring perch, and remounting in a different bolt location. I set the height and preload and will no doubt be readjusting a couple of more times. Of note, the preload wrench for the Ninja works great on the preload rings on the DR.

I ordered a couple of parts for this so reassembly will be another day or so, but here is the disassembly (pretty easy stuff).

Thanks to Yun Lung Yang(https://adv-traveler.com/yun) who provided the necessary incentive without having to say a word, the implication being clear "what are you, a wuss?", much was accomplished today. Before. The Mighty DR - Before(https://adv-traveler.com/136/photos/506/untitled/5309/the-mighty-dr---before) After: After(https://adv-traveler.com/136/photos/506/untitled/5310/after) The farkles: The Farkles(https://adv-traveler.com/136/photos/506/untitled/5311/the-farkles) It was an impressively productive day. Yun suggested we turn wenches so I reluctantly agreed knowing that it needed to get done. Nearly 6 hours later we had virtually everything completed. AGrip(https://adv-traveler.com/252) would walk in from time to time assuming what was traditionally my role of "management" and point out things that we were missing. It was invaluable. The driving light mounts that I purchased turned out to be a failure. They simply didn't fit the application so Yun and Audrey drilled the reflector brackets and mounted the lights there. The kit did not come with a separate switch so, again on Audrey's suggestion, we ran wire in preparation for me getting a handle bar mounted switch and relay for the lights. The lowered Sargeant seat is MUCH harder than expected. It may not be workable but I'll give it some trial runs before making a final determination. The Sw-motech center stand is a thing of engineering beauty. It fit perfectly. It's funny, but coming from a BMW background I'm used to things fitting perfectly. On the DR with aftermarket parts, not so much. The Wolfman side racks were a bit off and had to be torqued in order to fit. Very Annoying. As I mentioned above, the mounting brackets for the driving lights also did not fit. The headlight guard on the other hand fit perfectly. The IMS gastank had a big warning label indicating it was, in the state of California, not to be used for anything other than racing. I guess we'll avoid California. Honestly, I can't believe we got it all done today. It was a lot of work.
