    2017 XR650L blowing blue smoke at cold startup

    My 2017 dr650 with 11,500 also smokes occasionally on start up but theres never any noticeable oil usage so I just chalk it up to a little oil pooling in the intake, because if I’m really beating on the bike it seams to smoke worse the next cold start but its not every start on mine, and my dad has a 2016 dr650 that does the same, its normal just think of it as extra lubrication for the rings.

    650R Supermoto Cush or no Cush

    Cush drive will make for a smoother ride and prolong the life of sprockets and chains. But It’s really to each their own.

    dr650 dies when given throttle

    Yea it’s possible that the choke is partially activated and in turn the bike is rich and when you blip the throttle it just floods out.

    dr650 dies when given throttle

    I did the same thing to mine and it works flawlessly, got the idea from adventure oz. make sure the petcock vacuum is hooked up, or capped off and than make sure your choke isn’t sticking.
  5. Get rid of the junk ass k&n and stick to foam you will notice a huge difference k&n’s choke the bike out trust me I’v been there and done that. And keep the side cover on and drill 1, 1.5” hole next to the snorkel hole. And it will run better than it ever has.

    1990 DR350 - Hard to start, runs for 1 second then dies

    Well all these motors need to run is spark air and fuel, so if it bogs down, smokes black and pops no matter what you do than its not the carb. Make sure you set the valves after the intake valves shut this is the proper tdc. If you set it right and it still does this my best guess is the timing jumped.

    Keihin FCR41 - what bikes use them?

    My bad it was an xr frame with 84xl motor, and I don’t recall ever saying the old carbs are better..... their not, but I personally never had a problem starting my bike old bike, 2 kicks cold, 1 kick hot and usually around 25 kicks after a tip over. And what i was getting at when I asked why he wanted that carb was the fact that its an 89 xr600r, it is a great bike and will out last most bikes 10x over. But if he expects a totally different bike he should know that it will have better response but thats about it for the amount of money and work he would have to put into it the cons out-way the pros for me. And I have ridden a bike with a flat side pumper carb, and it was god awful on the trail to jumpy great response but way to peppy for the trail. Heres a pic of my old bike..... regretted selling it until i got my dr[emoji41]

    If you dont mind me asking why exactly do you want that carb for that bike, I used to have an 84xr600r and that was the dual carb setup and never wanted a better carb, as the older bikes aren’t really emission choked like the new ones.

    Yz450’s used them, maybe yz426’s, i dont know that it will drop in but should be pretty easy make sure you get as much of the hot start assembly as possible

    Will a xr 650r slip on for work on a Honda xr 650l

    Yes it should work But it will take some re engineering, heres a good post on what to expect to have to do: Xr650r muffler on a 94 xr650l will it work? https://thumpertalk.com/index.php?/topic/1046797-Xr650r-muffler-on-a-94-xr650l-will-it-work%3F

    Dr650 fuel in petcock vacuum line?

    Was the petcock on prime, if it was that bypasses the vacuum and lets gas flow freely
