    I love the new sprocket ratio: 14/48.

    After ripping around play riding on my XRL, I stop and see gas running out of the drain hose that comes out of the bottom of the carb bowl.

    i assume that the floats are stuck and overfilling the bowl and this is the overflow drain. Correct? If so, why would they suddenly stick? Any ideas?:huh

    Valves came in. get to lap them tomorrow. though i noticed the new ones i ordered (listing was for an XR600R but they share the same part number as an XR650L) have a diff shape to them. they are the same size, diameter etc but my concern is the recessed dome at the bottom.

    the stock valves have a wider dome at the bottom. these new ones are mostly flat with a small dome in the center. will this be a problem? will I lose compression? gain it? actually my main concern is will this modify the squish bands negatively and cause the motor to be less efficient. :ear

    stock valve is obviously the one on the right.


    Edit: they may look like diff sizes in the pic, but they are both the same size. these are the intake valves.

    give the carb bowl a good tap with a rock or stick (ideally, a hammer if you have one on you while riding) to help unstick the float needle valve. it could just be dirty and need to be cleaned.

    sorry for posting this question twice but i want this to be at the top of the new page so everyone can see it easier.

    Valves although look like diff sizes in picture, are identical in diameter / circumference. both are intake valves with the one on the right being the stock intake valve.

    if you have an aftermarket tank check the check ball in the cap.
    mine did this a few weeks ago and my little ball in my aftermarket cap was plugged and my tank hard as a rock forcing fuel past the float. just a possibility

    this is why i bought the cyclops enduro light, i hated my stock light set up, it was always too high or too low and always got knocked out of sorts!

    Man, I was hoping that was the issue, but not this time anyway. Good knowledge for down the road though.

    So I pulled the carb, removed the bowl, and to be quite honest, I found nothing out of the ordinary.:huh Not sure what to think. I bumped up the main from a 155 that I put in when new to escape the factory lean condition, and popped in a 165 main as I am removing the snorkel and doing a full exhaust while everything is opened up. Also finishing the Dave's mods, and doing a valve adjustment check. I'm at 4,500 miles, so it probably wouldn't hurt to have a look at them.

    So, is there something I am missing on the overflow issue? Something to look for?

    When removing the snorkel, and adding a full FMF exhaust, is going up 5 on the pilot from the 55 I put in to make it run good stock, to a 60 sound about right? And replacing the 155 I also put in it to run good stock with a 165 sound about right? Motor all stock besides these intake and exhaust mods running a stock air filter. I have a 170 but that might be too much.:ear Please chime in!! Thanks!!

    No, but if there were a bike that was, this it.

    Occasionally, they will bind, sometimes they are on the border of being out of adjustment, and the float valve can wear a ring in the seat.

    I took my new and newly plated XRR out on it's maiden voyage in the hills near my house. I'd actually never been on this trail before and was thinking how lucky I was to be on my XRR and not my XRL. No sooner did that thought cross my mind when I run across this poor schmuck on his XRL attempting the same trails. He was backing down from a failed attempt on a steep part of the trail and said this was his 4th crash of the day. Not saying I couldn't have made it on my XRL, but it would've been a lot harder.

    His bike had the relocated battery, XRR sprocket and fork brace and pivot pegs and pipe. Pretty nice 2005 with 10K

    My XRL feels a lot heavier and less powerful. Now I felt like I was on a dirt bike. I've got a windshield and Pelican on my XRL though.

    My xrl has all the usual desmogging/derestricting mods, Daves mods, uni filter, Big Gun exhaust, a few parts changed/removed for lighter weight, and slightly lowered/revalved suspension. I'm 6'3" so the bike fits me well. The bike runs mega strong now with instant throttle snap, and I've NEVER came across a situation in the dirt where I needed more power...the bikes a tractor that also revs quick and hard when needed, and I've never failed to make any obstacle because of a lacking on the bikes part. If that guy couldn't make the hillclimb with his similiarly modded xrl, it wasn't because his xrl didn't have the power...he just didn't have the ability. I've been riding since I was in my early teens, and I've taken my xrl up some unbelievable hills, feet on the pegs, in complete control the whole way.
    I'm not trying to brag, just saying the bikes very capable, its usually the rider thats lacking :D

    But then thats the case in alot of situations :evil

    For a stock piston/compression ratio the 160 is going to be to rich.

    The overflow is probably some dirt in the needle and seat. Open the float bowl drain screw and turn on the petcock. It may flush the debris away. If not then you'll have to open the carb for inspection.
