After the Procycle carb mod I ran into some issues. This is my fix. If you have a different fix let me know. Adventure Oz DR650 2b power mod: • DR650 project: transfo...
I have 2 DR650s. I ran the carb kit on my 1st one for a bit, with the airbox cut and an FMF pipe. It was loud, especially if it needed repacking of the pipe. I was riding too many miles for that. I use stock pipes now. Ti GSXR1000 pipes are rare and expensive now. Now, one has the allen-head screws, an adjustable OEM overseas needle, an extended idle-mix screw, and a snorkelectomy. The other has an adjustable KTM 640 needle and the other stuff. The breather filter has been moved away from the airbox opening. They both run great near sea level. Winter time is made better with a slight idle-mix adjustment. For higher altitudes, I could remove the airbox door. They can be returned to stock pretty easily. A lot of other needles don't have a great taper, or they can wear out the needle jet quickly. This is basically a simple upgrade that makes the stock carb easier to adjust for elevation and temp, with a bit more airflow from the snorkelectomy. I rip wheelies in 1st and 2nd.
Bought mine,rode it a few hundred miles, stretched it out on the highway and it was good for about 96mph.went home, backed off the valves a couple thousandths, took it for a ride,105 mph all day long with me on it 165lbs.thats the only power mod I've done and that was 20,000 miles ago.
I did the Procycle kit and have had no problems yet. 5000km lots of offroad. I followed Adv Oz's video for install. Love the power gains! Its like a totally different bike.
Dave, you said you followed Adventure OZ's video for the install. Did you clip your throttle spring? If so, how much? In the Adv. Oz vid, I think I remember them taking off 1.5 cm, but all the other material I've found says - if you're gonna do it, only take off 2 springs (~ 2-3 mm).
Yes , if i remember correctly i followed every thing Adv oz did. I think with all the experience those boys have i trust them. lol The procycle kit really unleashed the beast. I found that i lost 20km/hr off the top end but the DR is pretty uncomfortable up there anyway and 140km/hr is lots for me. Cheers
Wow! The fastest I've ever had my bike is 140 km/hr (87 mph). But here's what makes me wonder if I should clip my spring - I live at 3,800 feet with frequent jaunts up to 7500 feet. The average elevation Down Under is 330 m (1083 feet.) I'm not sure what effect elevation has on a carburetor, so I'm not sure if the potential issues with clipping the spring would be exacerbated at higher elevations. Anyway, that's what I'm trying to figure out.
@@843292 elevation effects the air/fuel mixture on a carburetor. As you increase in elevation the air becomes thinner but the fuel remains the same so you end up with a richer mixture.
For those wondering; procycle includes the correct spacer with a flattened side in their kit now, just like what is done here with the modified o-ring. ua-cam.com/video/UJbS5zwUTzA/v-deo.html
Issues like that, plus other annoyances, are why I tossed that CV carb and got a TM40. All issues solved, including that irritating low Rpm lugging or chugging, which is eliminated.
If you notice the area around where the carb draws air is so cramped and the carb needs to draw a lot of air in order to 'breath'. What I did was to fabricated a side cover for the box with a big hole and covered it with a wire screen to prevent debris from being sucked in, then cover the original hole on top of the box. The space then was left solely for the breather filter. With this it eliminated my surging at high speed. I am also using a procycle carb kit.
I was wondering about that surge. I just figured I didn't adjust the needle correctly. I was going to tear it down during the winter but perhaps I'll do this instead.
Gamet36 - you adjust the needle only once, that is when you get the correct idle mixture and rpm for a specific terrain elevation. It has a very minimal effect during high rpm operation, if I'm right :)
I got the ProCycle Breathe Easy Kit on my DR650 & cut out the top of the air box like on the instructions but I had the same problem with the secondary breather filter. I ended up making a divider to go between it & the airbox that way there not so close to each other & so far its been working good.
I like that procycle carb kit. I had plugged the vacuum intake when i first did the carb mode. Wasn't till later i had the same problem as you did. Must have read the same post you mentioned as moved that breather and also changed out the foam in there. Stock header/exhaust .. Had my problem in 2014 or 2015.
I had exact problem. . My float was stuck open and was flooding the carb. Wouldnt accelerate, hard to start. Filled my airbox with gas when I got home.
@@narrator-timothymckean Spoke to my bro and he told me he ended up replacing the carb with one from an SR500. A nice Keihn FCR42 would work very well 👌
Us Canadians too. If you want to know most anything about the 650 the Aussies are the best. Check out Biker Bits as well, another Aussie doing the 650.
Right on! Mark Victor - Bikerbits: ua-cam.com/video/EH3G8vE4yfk/v-deo.html Mark's videos on the DR650 were one of the biggest reasons I chose the DR! And his videos have also helped me avoid a lot of mistakes with my bike because of his open and honest approach to his mods. But, big shout out to Adventure OZ! I LOVE their disclaimers! So funny!
Biker bits was my deciding factor in buying the DR and OZ made me chop up the carb. It ran great for a few thousand miles, now I have this guys problem. It didn't happen suddenly like his, it slowly got worse on a couple hundred mile trip through the mountains.
I know this is old, but... Just bought this Dr used and riding it back home it started acting up like that, but not until i was trying to run over 55 MPH. I thought it was starving for fuel. Going to have check the position of that vent. What gets me is that killing the engine when paying tolls, every single time i had to give it full throttle for it to start. Well check position of that in the morning.
@@Gamet36: haha, there's a novel thought. I remember a version of I love Lucy from 60 years ago when she said "hey, remember when garages used be for cars?"
Great vid mate especially as you get the problem on film. I will remember that for future. I would have thought fuel / carb issue especially as you almost dropped it just beforehand.
Hi, I bad listen english voise) Can you write - what is the problem and how you fixed she? This only procyle kit, or dynojet too? And give please link to your forum topic with it.
The instructions for my dr650 JD kit says to cut a 2x4 hole which seems small, smaller than 3x3. Every other jet kit basically says to remove almost the entire air box top. I'm afraid to cut too much now.
Hey, are you still in the Grand Rapids Michigan area?? If so, I've got an FCR on my DR650 that was built up by none other than the man MXRob. It runs great and would be interesting to compare the FCR to your ProCycle mod. Oh, and I'm just west in Allendale.
2 questions 1). Where did you get the bag/luggage carrier and 2). How many miles are on the Bike? Dealer told me not to do any mods until 2,000 miles and I am there now same bike as yours though, 2015. Funny I have the same Luggage rack!
I got the bag from Revzilla I believe and I have 9000 mi as of today. I waited til my 12mo warranty expired before I did any engine mods. That way if I had a problem with it, they couldn't say it was because of the mod. I don't think it matters for the mileage if you want to do the mods. Adventure Oz did his before he hit 1000 I think.
It does what I wanted it to do. Keeps the wind off my chest at highway speeds so I don't feel like I'm being blown off the bike. Makes those long trips much more comfortable. I don't notice any buffeting on the helmet and I have clean air hitting my head. So it's good. Much like the trashcan mod a lot of guys do.
It wasn't. But I did end up turning choke full on to clear it. Once it cleared I turned the choke off and it ran fine. Once I got home I rerouted the secondary. I haven't had a problem since.
It turned out that I needed to turn the choke on to clear it. Then, once home, rerouted that secondary vacuum and all was good. It never happened again.

Midwest Michigan, Cool! Represent
so you didn't do what pro cycle told you, interesting
In one of Adventure Oz`s vids, he talks about changing that filter out for a much larger aftermarket filter.
Yep that secondary filter can cause the bike not to start if its real dirty. I am replacing mine, with a larger one I bought on pro cycle.
I like that procycle carb kit.
I had plugged the vacuum intake when i first did the carb mode.
Wasn't till later i had the same problem as you did.
Must have read the same post you mentioned as moved that breather and also changed out the foam in there. Stock header/exhaust ..
Had my problem in 2014 or 2015.
use a raptor 660r petcock if you can . it eliminates the vacuum function in the petcock
Thanks for uploading this, I have a jet kit on the way and am trying to educate myself as much as I can.
I got a 2021 with a 150 jet Dominator exhaust but no mods to air box. Running Avgas runs like a swiss clock. .
Plug the vac line and take out the stock tiny fuel filter in the carb inlet and put a larger one in line.
I had exact problem. . My float was stuck open and was flooding the carb. Wouldnt accelerate, hard to start. Filled my airbox with gas when I got home.
Could be more likely the float was stuck after the little drop ,
My brothers old XT500 suffered this same issue and has the old style carb, no vac slide. Ended up being float issue.

@Edward-pf3lo YES. YES it is.
Thanks for sharing, this info is much appreciated
Yep, same thing happened on mine. Not a float issue.
You've nearly got it. It's atmospheric surging. My DR is unrideable because of it beyond 90km/h. Bought the TM42-6 to alleviate. Will see how it goes.
How has the tm 42 been.
Well ??

I'm fighting with hesitation at WOT... too lean... too rich.... Can't quite get it
Bush Pig keep in mind you may have to play with the needle too not just the mix screw.
Try it at wot with the choke on. If it helps its to lean. If not, too rich.
What's "this?" As in ," you have to reroute "this."
Yes. The breather had to be routed away from the primary air intake. They were competing for the same air. After that it was great.
@@Gamet36 might be my issue. Thanks
