The DR will see occasional use by me on the trails, but that won't be it's main use. It will mostly be used as a first bike for my girlfriend who's wanted a motorcycle for a couple years now. She's already taken the MSF course and got her endorsement. The DR makes a great bike to learn on so I feel it will do well in this role, with one exception - seat height. If I'm not mistaken, the DR has a stock seat height of 34.1". My girlfriend is 5'4" with a 30" inseam. I've got the bike on 17" supermoto wheels, which effectively lowered the front end by 2". I'm going to try lowering the rear by moving the rear shock bolt to the other hole as I've read can be done. This should have the added benefit of fixing the steering geometry. Switching to the 17" wheels without lowering the rear at all changed the rake/trail enough to cause a bit of a wobble at 80+, so hopefully that disappears.

The question I have is this: After I lower the rear as mentioned above, my math tells me that the bike will still be 2" too tall for her. What are your recommendations for dropping an extra 2" in seat height without destroying the steering geometry or causing the tires to hit the fenders when the suspension compresses? Anything I do has to be reversible and ideally wouldn't be too expensive. I will of course have her give it a try after I lower the rear to see if that is actually enough, but I suspect it won't be.

I appreciate the advice [if anyone actually bothered to read this long-winded post] & I have to say, this thread is great. I've learned a ton from reading this stuff.
Her inseam is enough for an unlowered DR with stock tires and seat...once she's comfortable on a 370lb bike. I easily ride an unlowered DR with a 30" inseam.

Fix the geometry, as mentioned before, by factory-lowering the rear. It might be low enough for her as is then. If not, Seat Concepts has a low seat re-covering kit for the DR now. You could also slide the forks up in the clamps and get lowering links for the rear. The DR can be made really crazy low for a dualsport.

If you lower the suspension, you're going to want a lower sidestand too. There are adjustable ones sold on Ebay. Some people also make their stock stand adjustable by cutting, tapping threads, and inserting a threaded rod with jamnuts on it.

I'd recommend to actually have her check the bike in it's current form, before making any additional changes, it's likely a very good fit if it's already 2 inches lower than stock. Seat height does not need to be equal to the inseamn, at least not on a DR.
I have a 29" inseam and I ride the stock unlowered bike, it is a bit on the high side for me but absolutely manageable given the relatively low weight (for a 650) and the narrow seat (this helps a LOT). I wouldn't be surprised if she almost flatfoots the bike in it's current form.

Shorai Battery

These were cool mornings, not cold by any stretch, 50-52 degrees. Each time I was getting ready to pull the seats off the bikes and use my jumper cables and you try it "just one more time", and it would finally start. Had NO confidence in that battery.

Wife's DR200 failed to start several times, not even on cold mornings and would randomly act like the battery was completely flat necessitating a bump start. I checked it each time and the battery connections were tight. Have been running a good old lead acid battery for over a year now with zero issues.

That was a few years ago that I had the Shorai in my CBF and since then they have increased their recommended battery size. To get reasonably reliable performance from these batteries you have to way over size them, which makes them even more expensive. Personally I wouldn't use one of these when a good old fashioned much cheaper battery is good for at least 4-5 years of service for me.

This is one of the threads about the new batteries, lots of technical info but interesting read over the winter.

Thanks for all the answers. I'd say the "consensus" is that the Shorai is not a good battery for the DR, at least not for serious off road.

So Ive had a DR650 for a few years now. I put a RM250 front end on it and had the shock redone. Bigger tank and wolfman luggage and a concept seat. The only mod I havent done is a pumper carb. I live about 20 miles from Jessi at kientech and he has new pumper carbs in stock. The bike runs great and will handle most of what I throw at it. I miss the snap that a dual overhead cam motor has to offer. Would a pumper carb over come this or would I be better off with a more modern bike?

A pumper carb gives better throttle response and low-RPM luggability than the typical CV carb.

There are now all kinds of things you can do to a DR motor. I'd talk to Jeff at www.procycle.us about high-compression and big-bore pistons, aggressive cams, and big-valve heads. Talk to Kientech and MX Rob about exhausts, EFI, and iridium sparkplugs. 14/42 sprockets will also give you a bit more grunt than stock.

What exactly do you want the motor to do differently?

I have had the CV carb and the pumper with fmf header and Gsxr pipe. IMO save your money and keep it stock. If you want real changes you have to go big bore and then the cost and reliability weigh in and then I think you should just look at more modern bikes.17 year old air cooled technology is best left alone and stock.

I'd suggest you go as low as possible to start. The DR is a heavy bike for beginning riders, especially females who are apt to have limited upper body strength. I think guys sometimes fail to take that particular point into consideration. I've had good results with a Seat Concepts standard height kit with FIRM foam. Then use a belt sander or electric carving knife to shave it down to height and narrow it a bit along the sides where it meets the number plates. The firm foam is good stuff; it can be shaved thin and still offer better support than the crap stock seat. I tried the low kit and did not like it. It was too soft and felt like it had a dip cut in it that kept me in one spot crammed against the tank. Most of us agree the stock foam is trash. While you're pondering the Seat Concepts kit, go ahead and take the stock seat apart and shave the hell out of it so she can see where she stands. You may want to pull the factory foam off the pan entirely and try a couple layers of carpet padding or some such to start. The cover will go back on and tuck under the pan enough to be usable without the staples. I know all this must sound fairly crude. Please bear in mind I'm a redneck from Kentucky; we go at most things with a pocket knife, baling twine, and duct tape.

IMO 17 year old tech needs fiddling to get the best out of it. A pumper and pipe make a big difference.

My experience: the CV stock vs.Pumper/header/GSXR pipe made a small difference,to say nothing of the drop in gas mileage and the $700+.
IMO,not worth it. (BTW,jetting per Kientech)

At least 90% or more who changed out to a pumper carb would disagree with this statement.I may have lost 5 mph,but the fun factor out ways that big time.It all depends on where and how you ride.It's the way the fuel is delivered.Nothing wrong with stock,but most us just can't leave things alone.It makes the DR motor run like it should.People who have bad mileage have poorly jetted/setup carbs.Talk to the people with the Dyno Jet kit who get crappy mileage,it's over jetted. Stock HP is 34-36,with the mods about you are close to 40.HP cost money,If that is you want to do.And it runs a hole lot better.And you don't have to spend 700$ if you do it right.
Stock cark/Dyno Jet vs Pumper is apples and oranges,for me how and where I ride it well worth it.
My FCR-MX DIYwas right around 200$ installed and running.Exhaust:35FO,mid-pipe and flange right at 200$.Took some time ,but then again I am a cheap/poor bastard.

Im speaking for myself.Sandwash is speaking for "90%"
You do have to spend $700,as stated unless your buying used stuff.
You say"some people just can't leave things alone" that is part of the problem
I say start with a $18 engine sprocket and a tuned carb and keep your MPG and better altitude compensation.

A flatslide with an AP will provide quicker response than a CV, but in the case of the DR, it's not a dramatic difference. I'm happy I swapped to the TM, but I'm also happy I found a used one.
I've heard the DR650 motor described with a lot of complimentary words, but "snappy" ain't one of them. Look at its power output on a dyno chart. The torque curve is pretty flat, not spiky. It's more of a tractor engine than a sportbike.
You might be better off lowering the gearing and adding 1/6 turn throttle tube if you want to feel the acceleration faster...
