    I've wondered if you could run inverted forks with the Acerbis tank... guess this picture answered that question. I have access to a set of YZ125 inverted forks and have pondered doing the swap-out.

    With the stock carb, you are limited to what (if any) needles are available. There may be other needles that came out of similar carbs from other bikes, but there hasn't been much work done on sorting that out for the XRL. That leaves you with shimming the stock needle to approximate moving the clip on other needles. As far as the needle profile goes, you are pretty much stuck with what you have. Most who mess with different needles are running an FCR carb. The "tunable" carbs like the FCR can be as much of a curse as they are a blessing though. If you have it tuned right, it rips. Getting it tuned can be a nightmare though. There are so many more variables to play with.... it can lead to carbs flying across the shop.:lol3

    I'd get so much better gas millage if I would stop listening to Sammy Hagar :D

    So what jets do you guys recommend for 0-1000', actually mostly between 0-500'? I have yet to do Dave's mods.

    Ya. Bike is going to be pretty front heavy with $120 of steel up there.

    I'll probably try and mess with the stock carb first. at least it only has one! The FRC carb scares me for jetting as well. :eek1
    We have had some later posts about jetting. Now I'm confused! Have to figure out what I have 1ST. Maybe buy some jets +/- either way so I have them on hand? Spark plug sparks but i oredered new plug anyway. Snorkel still in place. Supetrap muffler and stock header. K&N filter element. When motor is cold bike doesn't start (or at all) well when even 50 degrees F cold with full choke. I'm pretty sure i flooded it last go around. I actually think it might be a tad rich. Maybe? or, I don't know WTF I'm doing. :rofl

    My reccomendation to him was simply to reverse the Dave's mod step of raising the needle, dropping it back where it was, not replacing it. Some "jet kits" include replacement needles to address the different distribution of fuel delivery with respect to slide position. It's either trial and error, or duplicate someone else's findings and hope for similar results.

    It's been puzzling me how I can so easily tell the difference between running rich and running lean, especially since so many people seem to have trouble with that. It just hit me that I grew up in the era of adjustable main and idle jets so I've been fine tuning mixtures since I was a kid. When you can adjust at whim, and get instant feedback of the results, it's easy to learn to identify the conditions.

    That's running; it's harder to judge when it won't start. If you prescribe a starting procedure, then alter it until you find the recipe, that will help sort it out. Writing it down will help you from getting confused (e.g., crank twice for five secs with full choke no touching throttle, then twice at mid choke, then twice at no choke, then twice with throttle cranked open). Keep trying recipes like that until you find a reliable one. Raw gas smell in the exhaust pretty much indicates flooding. To know, pull the plug real quick and see if it's wet with gas.

    Here let me help! :evil

    I seem to recall a discussion here a while back about the jets from Dyno-jet not being the same matching numbers as the stock ones(Keihin) from the dealer or Jets-R-us?

    You know, same diameter hole but a different number.?

    That's a good idea. Be more systematic and write it down. Especially if beer is involved in the equation! My memory sucks.
    It was starting/ running fine (but not perfect) the weekend before last after I bought it, but then something changed. It's not run since, but I've not spent much time with it either. No time.
    Like I said, I was really thinking about just buying a pumper carb if I went the Suzuki DR650 route, from all the banter over there about them not running with the stock carb. I was hoping the stock XR carb is better, but not so sure now?
    Family stuff this past weekend so I couldn't spend any quality time with the XR. My motorcycle trip to PA next weekend is on the ST13. For sure! But I'm going to miss out on the DS rides. Oh well.
    I've only had two other bikes I messed (up?) with the carbs before and they were both twins with two carbs. One I got running nice. Honda. The other, not so good. Suzuki. :cry
    I think I'll get it sorted out.

    Anybody have any experiance with one of those inexpensive tachometer/ hour meters. Like in the $35-$45 range.
    Thanks,

    They also seem to not play very well with the stock needle.

    'Any goob' can tune a carb, so to speak, the fact the L even has a popular recipe indicates it's a fussy barstard.

    Thanks! I do remember they have a chart but can't seem to find it on their site.



    That pic sure does get used a lot on ADVrider...:evil

    I just want to know where he keeps the hair dryer on the bike for cold starts in the woods. :dunno

    Mine runs well with stock 50/152 from sea level over 4k.

    Do Dave's Mod and start with 50/152, then try going richer one jet at s time if is too lean. Mine likes the 50/152 combo.
