Does my DR need Viagra ?

Recommended Posts

Can't get that wheel up... O.K. I'll start off with this disclaimer..I know that wheelies are not the best indicator of performance or rider intellect. That being said it seems like every other post I read mentions a DR650's front wheel coming up with the blip of the throttle. Mine is a 99, stock carb, no snorkel, 14T counter sprocket operating at about 4800'. Are serious mods required to loft the front wheel with just a twist of the throttle ? I'm pretty sure I can live without doing wheelies...but it would be fun, just once.

Hi

I have an 08 and i dj jetted the carb i opened up the air box i put a fmfq2 pipe on i went to a twinairfilter and a 14t cs and there was no way the bike was doing roll on wheelies, now there are guys saying they can with just about stock settings i call BS unless they are supermen who can yank up the front end but i just installed the FCR mx carb and now the wheel comes up i think if you went to maybe a 14 45 combo you may get it with out too much trouble otherwise stock or close to it no frigging way i don't care who you think you are its not a wheelie machine:p

Thumpty, if you have the snorkle out and shim the needle it should have some lift in first gear with stock gearing. Open airbox and dynojet or flatside will have some wheel lift in second gear. With my FCR set with mild jets I have to be careful about grabbing a hand full in first because it will loop on me in a heartbeat. The way I am setup now, I can get some lift just using the throttle in second but have to help with a good yank (no clutch) to come up to a balance wheelie in 2nd.

The ability to wheelie is much more dependent on throttle response. The stock carb responds to throttle slow to there's no 'pop' to pop the wheel up. Getting the jetting dialed in or better yet a flatslide pumper carb will make wheelies very easy.

i have an 08 with airbox mod ,dj kit ,ground header, 14 t sprocket ,and supertrapp exhaust and wheelies are not a prob at all.no clutch needed i find it hard to believe some cant do it , mine comes up in second with no clutch just a little bounce to get her started then strait up she comes..

Jeff, I realize that you sell a wonderful flatside setup but what you should be telling him (IMHO) is that with the snorkle out (he didn't mention if the needle was shimmed) and a 14 tooth CS sprocket, is that ... the thing should throttle wheelie in 1st gear because, ... well, because it should. I did my quest for power 1 step at a time so I have been there from the enemic stock setup to overly rich flatside. There is a hell of a difference and in my opinion, well worth the money for the flatside but extra power can be found cheaply on this engine.

The day I pulled the snorkle out was the day I was hooked on the quest for power. I went with the dynojet kit and was drunk on power even though I at first was usig the stock Mikuni 140 main jet with the open air box and te DJ needle. I went on to play with the tuning all the way up to the DJ 170 main jet.The bike ran like a raped ape but still I knew that I could have better throttle response.

Then, I heard about the Keihin FCR39 MX and jumped on that. I was astounded by the performace (throttle response). I could wheellie at will in 2nd gear but I soon realized that I was using fuel like an Apollo rocket so then Rob did a dyno run check for jetting. Well, the settings are different now and the raw output is a bit softer now but you can have throttle wheelies and decent fuel economy.👍 I do love my flatside so I might have run off track for minute here. The main point is that you reallly don't need a sweet flatside carb to do throttle wheelies in first gear.

Mine will wheelie in second with no clutch, and it has stock gearing, dj kit, two bros m7, air box cut, and header ground. I find that I have to crack it in the bottom end to get it wheelie, this bike has the best throttle response in the lower end with the cv.

Thought it might just be the loss in power with altitude until the guy in Nevada chimed in....It would seem that ( I'm no expert, so don't beat me up too bad ) low end throttle response would mainly a jetting issue, gearing and pumper carbs aside. I say that because I imagine that just off idle the airflow is not large enough to have things like air box and header welds come into play. When I pulled my seat off to remove the snorkel I noticed that my secondary vent line was mashed nearly closed ( probably has been that way since I bought it new )...what effect does that have, if any, on throttle response ? Does the slide drill mod really work ?

I've done no carb mods or adjustment as of yet. I did order the Twin air filter from ProCycle yesterday. I'm stuck with the stock carb for a while..Need to get some new ridin' gear

I think too that if you try to make it wheelie a little harder you can probably get it up in second, stock. You'll need to weight then unweight the forks while at the same time cranking the throttle; be very low in the RPM when you crank it, the DR will never lift off in mid-high RPMs. Think of it as an asissited roll-on. This will definitely work from first too, especially with the 14T I would think.

usual mods for me (DJ, K&N, staintune, airbox mod, 44t rear) and i power wheel after she starts to move. 2nd comes up to with a little help from the clutch.

too scared to take it to balance point - dont know how far to go or how to hold it there.

another thing that you wouldn't think about but helps HUGELY is doing the suspension. The stock rear spring saps so much 'snap' out of the engine you wouldn't believe it. After putting springs in both front and rear the responsiveness improves tenfold I can now scrape pegs through a tight corner then simply lean up straight and roll the throttle on and it'll pop up straight away. I even did a 3rd gear wheelie today running 15/41, not rollon of course but snapped it up in 1st through a corner then banged it through to 3rd. But 1st will always pop up just rolling on the throttle, 2nd will if you give it a bit of a tug, clutch it, or are standing

If you do the DJ install AND drill the slide you should be able to get it up, and the suspension helps even more. Mine will come up anytime I feel the need so long as i'm not doing over 70kph since it doesn't have the horsepower, its keeping it up that I have problems with 👍 my record so far is about 200 metres

Its funny to me when people her say that these wont wheelie with the stock carb modded. My 07 , when I had the stock carb with dynojet kit, no cover on the box and just the Q2 muffler wheelied effortlessly in first , second would require a lil clutch action 50% of the time. I like to stand it in 2nd and shift thru as many gears as possible.

After installing the TM40 , it definately walks up now 1st & 2nd and sometimes if your in the right power curve , 3rd gear as well coming out of corners. But now I'm having trouble shifting while the wheels in the air , I think due to the acc. pump, its so snappy that its funky doin the quick blip to grab the next gear. I literally could lift in second and shift to 4th or 5th with the stocker easily......... what am I doing or have done wrong ?

my pretty much stock dr will wheely!

got snorkelectomie and shimmed needle plus second hole in slide, shortend carb spring by a couple of winds, and drilled a few holes in the back of exhaust, and header weld grind done. all easy and "free" mods.

i can lift the front wheel in 1st without clutch, wide open throttle, and you do wanna lean back a bit!, move your wheight to the back. then when shifting to 2nd the front wheel usualy comes down and compresses the front fork springs somewhat and with a bit of luck will bounce me back up in 2nd

to make this really really simple, have the bike in 1st gear. Get it to about 30kph. Forget about the your lean, seating position and all of that. Close the throttle completely for about 1/4-1/2 a second then open it up all the way. If the bike doesn't wheelie then you need more responsiveness so either swap the carb or do the DJ kit + drill the slide

Sounds like the DJ kit will help....I'd like to hear more opinions about the slide drill. Thanks for the input.

BTW...Qwerty, That's pretty much what I'm doing...not happening for me...I feel ashamed...

Others...Is it still a called stock carb if it's got the DJ kit, drilled slide, airbox open, etc ?? I guess that might just mean its the CV BS40 that came with the bike

Yeah - what humpty said . . . more feedback on the slide drill results. I've read posts saying that it made a miraculous difference and was the best thing ever, while other people say they noticed no difference whatsoever. Why such a disparity in results?

It would be considered a modified stock carb.

I'm out by about 10k's, just tried it myself. Make it 40kph or roughly 5000rpm thats putting you around about the peak torque and where the engine will be its smoothest and most responsive. Mine will actually wheelie directly off idle even in 2nd gear with just the crack of the throttle but I compress and release the suspension as a substitute for power/responsiveness

And no I wouldn't call it a stock carb cause its not a stock/factory carb anymore, its 'the' stock carb but not 'a' stock carb. Just say DJ and everyone will know what your talking about, its a dynojetted carb.
