    Yes, I have joined that dark side...I sold my Dakar and bought a BRP. The previous owner had let this XR650R sit for a while while he rode his KTM, so I would like to do a complete fluid change and service the carb to make sure everything is okay. Right now the bike starts very well and runs well with the throttle on but will idle only for a few seconds then quit. It also slightly sputtered a coulpe of times, nothing big though,(i'm being very picky) maybe just needs some good gas run through it. Any suggestions and help would be great in bringing my new BRP up to tip-top shape.

    Is it uncorked?
    Does it have proper jetting? or a Quicksilver carb.?
    How long has it been sitting?
    Does it have fresh fuel?
    All that can contribute to the rough idle.

    If it's uncorked and has been sitting for awhile, I would think that the carb is clogged up. A simple tear down and cleaning the jets is in order. I don't think there are any Uncorked XR650R's out there that aren't on the dealer floor. Buy a Quicksilver for it as soon as you can, and always shut off the fuel when done riding for the day.

    Welcome to the Club.

    Its uncorked already, I just put fresh fuel in it but haven't run it a bunch. Sounds like a quicksilver carb is the way to go? What makes it so much better than the stock? Not sure about the jetting..what should the jetting be with the quicksilver carb? Also not sure how long its been sitting, a matter of months, not years though. Just bought a bunch of after market parts for it though..
    -baja designs dual sport kit
    -acerbis handguards
    -acerbis sahara 6 gal tank
    -black excel rims w/spoke kit
    -dunlop D606 tires

    An africa queens front fairing will be added later this year, along with a good seat. Any other suggestions?

    Looks like you've got a good one there. I've just finished the first part of my BRP project and it's set up similar to yours (Acerbis tank etc. I'll be posting a small project write up later this week). Took it for a 150miler this weekend to test it out, lots of fun, you should enjoy.

    I think jetting with the stock carb (uncorked) is 175 main 68 pilot and make sure the fuel screw is set (start at 1 3/4 turns out). Run some good fuel through it and it should be fine. Also check the valves. Let us know how it works out.
    Enjoy

    Thanks for the input.. I'll be going through the carb today and cleaning it. I'll let you know how it goes.

    The Quicksilver carb was the best upgrade I did, could never get the stock carb setup right. The next was a high output Ricky Stator with an 80 Watt headlight. The light from the BD kit with the stock stator is a little weak.

    Congratulations on the bike. I just finished going through what you are starting. Yeah, you can get it running fairly well IF you really do a super job cleaning all those small passages and spend some time sorting out the jetting. Mine is running well now.

    However, you can probably save yourself a ton of time and aggravation with the Edelbrock. If I had it to do over, I’d have started there. I finally bit the bullet and the new Edelbrock just came in the other day along with a 12 Kg rear spring. I’m currently waiting for my new speedometer to come in then I’ll wrench everything and get the bike inspected.

    If I counted my time on the stock carb at $30, the Edelbrock would have been cheaper... Changing the main jet isn’t too bad but all the others require a lot more effort. The Edelbrock has a couple of exterior adjustment and that’s pretty much it from what I hear. A lot of guys say it comes ready out of the box, I’ll find out soon enough.

    Some of the supposed benefits I have heard of is: Easy starting(!), better gas mileage, no peeing all over the bike, bike runs lying down so you can just pick it up and go after a fall, easy starting after the bike falls and you stall it, easy starting on non level ground, little more power (probably because it’s easier to adjust), crisp response off idle with out a lag and it doesn’t cut out on rough maneuvers; OH, did I mention easy starting?. The vast majority of owners love it and wouldn’t thing about going back while the people that never used it appear to nay say it. I did a lot of research on this prior to plunking down $400, and the fact that I bought indicates that research. I pretty much covered the cost by downgrading my luggage budget by $350... See http://www.advrider.com/forums/showthread.php?t=128969

    If ya do decide on the Edelbrock I’d recommend getting it here. http://www.barnumspro.com/

    Wow! Thanks for all those links, there are a lot of good stuff there..especially for dual sporting which I will be doing...One more thing, what would you suggest for a nice pipe that is not too loud?(neighbors)

    Until next time, my Sith Lord... :nod

    Ahh... You still have some good in you! I can feel it...

    I had the same concern, neighbors and avoiding Imperial entanglements...

    Initially did some research on that... Far as I can tell, stock is the best all around. Big bucks for aftermarket that only move the power away from the bottom toward the top. Seems like Honda did the pipe right...

    [​IMG]

    I went with the HRC tip (off eBay) and a Baja Designs Baffle. The neat thing about that setup is it’s QUIET and with the Edelbrock I can remove the baffle and go 4 clicks rich if I want to make some noise and have a bigger grin factor...

    I did the same, yet no BajaBaffel -- I switch it back to stock last night and went for a quick run-- I like the open pipe better.

    IMO you don't need the QS carb to make a BRP run right. My guess is you need new gas and a carb clean. Replace the plug. Do the simple stuff first. Have you tried raising the idle a bit? I prefer the "change one thing at a time and have patience" method of carb tuning to "spend $370 and get instant gradification". I haven't ridden a QS carbed BRP but it doesn't matter. This bike has more than enough power (for me) as is and I got 55mpg from my last tank of gas.

    Simple main jet, slow jet, and needle change will work wonders on the BRP. I had mine on a 175 main, 70 slow with the HRC needle and it ran great...but more importantly, it started easy.

    yes, and yes.
    be sure to put new plug in.... no sense in guessing about that.

    get the starting procedure down pat, 'cause if you don't you'll continue thinking something is amiss. [right fellers?]

    mine will be street-tagged just any day now.... yeah.:clap

    going to yank off that silly Polisport light, go back to stocker, but with an adapter for dual-beam lamp.... looks "normal"
