My FCR-MX has a very light throttle spring. When I got the bike, he mentioned that he had installed a lighter spring, I think from ProCycle. In fact, I almost find it TOO light. Often times, going slow, I will relax my hand and the throttle doesn't actually close all the way, and I have to make a point of closing it. I wish it was just a little stiffer. :)

Conversely, the throttle spring on my Polaris Outlaw 525 ATV, which uses the same carb, is freakin' STIFF.

I will need to tap into the tank near the top, or I will try to find another place to vent outside the tank that will not let water in.

I really don't want to drill into the tank, so Ill probably try to find somewhere else to vent to. Probably will try to find a small round ball that can float on top of the fuel in the clear line. I had a jetski that had an oil tank with a gauge like that, it worked great without any power or excessive tech.

Edit: I dont use the standard IMS tank cap, so venting to a tee on the cap would not work. I use the locking type cap.
It will be interesting to see what you can come up with. For me fuel gauges have only served as a rough guide ... I find actual mileage readings more accurate.

I've run my bike dry a few times ... and always ZERO odometer at fill up.
I've also run my reserve dry, so I know what my range is and know range of reserve as well.

Of course, you have to factor in conditions, head wind, load and road speed. I usually allow a bit of lee way and cushion. The 5 US gal. IMS generally gives 200 to 215 miles before running out. On reserve I can go another 25 to 30 miles. YMMV (after that you have to lay the bike on its side to get that last 2 liters that's hiding in there!

I agree!
So stiff I took it off and went back to my PC jetted stock carb. What a relief on my forearm and little noticeable difference in performance.
To me anyway

We're talking frame, wheels, tires, title, and all the other engine and body parts in bins (bike is technically complete except that the ?transmission? has some sort of issue, not really sure as the p/o took it apart and gave up with it).
I wouldn't pay more than $1K for it. I've seen running DRs in OK shape go for $1K.

Sounds like a good topic for a NEW DR650 Custom Dash Build Thread!
Go For It! I've seen some real beauties out there ... but would be nice to see them all in one place. Maybe add topic to DR index thread?

Tweak the suspension and no problems at all.

It depends on your size and preferences. I'm 5'8"/200lb/30" inseam and my GF is 5'4"/petite/30" inseam. We 2up a lot on the DR, even with luggage. Beef the springs for the payload.

I cut about 1" out of the rider peg brackets, so they're a bit lower. I added lowering brackets with 2 positions for the passenger pegs, so they're stock, 2" lower, or 4" lower. I also have Happy Trails touring pegs bolted to my skid. The best mods for 2up comfort for us though have been moving the Givi plate/topcase 3" further rearward and changing the seat to Seat Concepts foam.

Power is not an issue for me. My DR has a jetted BST40 carb, UNI filter, and stock exhaust at sea level. With 14/42, 15/42, 16/42, or 16/46 sprockets, it will still accelerate both of us and our luggage uphill from 80MPH (indicated) in top gear. Most stock cages under $six figures won't keep up with it to 60MPH, unless I'm babying it to keep the front end down in 1st.

It's no big touring bike, but if you're our size or smaller the DR can work. I'm more used to smaller ergos like on my old KZ440 and my YX600 anyway, but I've also spent quite a bit of time on a bigger GL1200 and a GS850G. The DR is more comfy now on the slab than my YX600 is. It cheats wind better, and I have the touring pegs to stretch out on. Phreaky Phil made a few other ergonomic adjustments to his DR and used it to do the TAT 2up with luggage, and he's taller than I am. There are a few others who rode from the US to Tierra del Fuego 2up on a DR too.

I put one on for my Blue Ridge Parkway ride and have not wanted to take it off.

It slips on over the grip and you position it so the heel of your palm presses it down. That way you can relax your grip and still keep the throttle open. I don't even notice it while riding tough offroad stuff. Got it on sale for half that price. a bargain if you ask me.

With my conservative solo riding, I get to 160 (+/- 5) before I hit reserve (alt 6000 and up). Since I'm riding locally, I don't think about gas until I hit reserve (low traffic situations so the stumbling when switching the petcock doesn't get me hit). Although I've ridden 39 miles on reserve, I put in 3.4 gallons when I did, it was empty. My point is: once I hit reserve, I have 35 miles to find a station.

fwiw: Although I get 60 mpg here at altitude, my mileage dropped to 48 mpg on my recent Kalif riding, no carb changes (snorkle out, + another 2" hole). (It's winter, the bike rode to Kalif in the truck. )

JUST the way I like it.

I ride roads often enough that when I need to stretch, wave, signal, point, pull something out of a pocket, etc... I do NOT want my throttle snapping back at speed.

I had a ZX-7R years ago with a slightly sticky throttle (it's always in the cables / routing), and have come to prefer a throttle that stays where I put it.

Now if I ever own a true dirt bike, yeah, I want the throttle to snap back on its own. But for commuting... I love light springs or just not fighting a throttle.

I first tried the Cramp Buster ... and similar devices 25 years ago. On a long, straight, boring stretch of endless pavement they are fine ... but very distracting in a any sort of riding where you are working the bike and throttle. Constantly gets in the way ... almost dangerous ... IMO.

But the MAIN THING IS ... the Cramp Buster does not solve the problem of a TOO STIFF return spring and still requires more force than it should. You can't do fine motor control on the throttle using the Buster. The palm of your hand is not good for accurate throttle control. Fine for steady state droning ... but nothing more, IMO.

The FCR Keihin Carb is much better. Light and easy ... and that is probably why most major dirt bike OEM's used the FCR over the TM. (now most are F.I.)

Maybe I'm the exception here. I use the extra-wide CrampBuster on all three bikes. Having come from ATVs and snowmobiles, both of which used thumb throttles, I had a lot of trouble adapting to the motorcycle twist-throttle. I found my right hand very quickly becoming numb.

So, somebody suggested the CrampBuster. The one I got was the wide one, since it's all they had. I put it on and set it up the "intended" way, to be used by the palm. Wow, that doesn't work for me at all. So I repositioned it. I moved it all the way to the left of the grip, and rotated it downward to about 45 degrees from level.

What I do now is I use my thumb on the CrampBuster, effectively making it a thumb throttle. The result is I dont have to squeeze the grip so much. I keep a very relaxed grip and can modulate the throttle very well, even in slow, technical situations. It's taken some time to develop the muscle memory and fine control, but it works very well for me.

Agree the Throttlemiester while riding offroad can launch you into the weeds !
My buddy uses one on his DR offroad and I don't know how he does it !

What I like about it is it's adjustable to any position. Even completely out of the way. No modifications, so it comes right off at any time or goes right back on. And it cost nearly zero.
