    Nope, 190 never a passenger or any heavy bags, prolly 20 pounds of tools, that is not the issue, check my links above for the full story.

    Let's keep this thread short and sweet, this is being discussed a LOT in other threads.

    Had the stalling and rough idle problem. Pulled the idle actuator and cleaned with Q tips(12) and carb/choke cleaner. Put it back together then cut the crankcase hose going to the air box and plugged that end. Took janets advice and went to Auto Zone and got a $10 air filter and 3/8" double barb splice and this is how it looks.

    That is great stuff, you should ask Gadget Boy to add it to the main sticky thread perhaps! I'll be checking it out this winter.

    P.S. don't go through deep creeks with this setup :)

    I did something sililar to my X-Moto about 3 or 4 weeks ago. I used the same filter but my hose is shorter and the filter is mounted in the up-right position.
    Have you experienced any soiling of the filter from blowby? Mine seems to be turning black from it and i only put a coule of hundred miles on it like this. I am guessing its being caused from the shorter length (the oil not sticking to the sides of the hose before reaching the filter element).
    If this length is working, I can do that, but if not, I may reroute it even further (maybe under the seat??????)

    One other note...... My cold start issue went away for a couple of days, but I have been gone for the last 2 weeks. When I started up this morning, it died several times. Temperature here is low 30's this morning.

    Did I miss something, has it been concluded that the crankcase vent is a/the culprit, for dirtying up the t-body innards? Tapping it with a filter instead of having it route to the airbox might be a good idea, but I don't think it proves anything, yet.

    Probably not the absolute fix but having pulled the idle actuator this weekend to check the cleanliness it was still clean and didn't have all the gunk in it like before.

    The pictures that i posted were the ones i took when i first did the mod. I have since also ran the hose and filter to an upright and higher position to avoid the creek crossing possibilities.

    Yes the filter gets a little blackish but that tells me that at least its not getting to the idle actuator due to the cleanliness of mine with the mod.

    I am also running a little different fuel mix than straight out of the pump..... nothing special, just a little ChemTool for cleaning and a little Mystery Oil for lubrication.
    I also use the prime twice, twist twice, prime twice start process.

    I wouldn't say any of it is absolute, but I can tell ya that i just went out after 4 hours and it cranked right up.

    Another successful startup at 3PM.... thats after sitting about 5 hours.
    Then another one a few minutes ago........
    To me, it looks like something is doing better than it has the past year or so. I just haven't had time to deal with the existing issues, but it looks promising. ALL THANKS TO THE INPUT ON THIS FORUM.
    It'll be down into the 20's tonight and I will check it again in the morning....... we will see what that brings.

    Its been 5 days since my last post on here about the starting after the crank breather modification.
    My bike has been sitting (unstarted) and nothing done to it.
    The temperature is somewhere in the low 30's / high 20's.
    I tried starting it and just like a horse that you haven't ridden in awhile, it snorted, farted, and kicked.
    I can say (in my case) that this mod did not correct the "Multiple Start Syndrome".
    On to step # 2............
    The injector modification?
    The "plug in harness" I read about?
    Any suggestions?

    Check your valve clearances?
    Could be the intake valves are way too tight, perhaps, or slightly open all the time. Similar issue with a friend of mine, turns out the valves were out of spec inspite of low miles.

    While I know that there are tutorials out there for the valve adjustment for the X-bikes, is there anything else that I should be aware of before tackling this?
    IE--- I have done the valves on my other bike and ended up cutting and modifying the top brackets so the head could be removed and replaced easier.
    IE--- I have machined down specific tools to fit into the sparkplug recess.
    IE--- I have had a spare seal on hand because I knew it would ruin the existing.

    Nothing frusterates me more than to come across incidentals that keep me from putting it back together complete.

    They are easy enough to check. You will need to have tube spanner or a 18mm spark plug socket turned down to external 24.5 mm. You will need an extension. I use the 3/8 flexable extention. Once you get the rocket cover off find TDC and if you need to replace a shim I would take it to the machanic. I took my bike stripped down to my BMW machanic and it cost me 1 hr labour and he through in the shim.

    I noticed a difference in the bike immediately so hopefully it will help with your starting problems. My bike has done neally 50,000 k's and apart from the fuel pump issues it has never let me down.

    I had an issue... :(: It's only fair to post about it as it could happen to anyone so here is a heads up. Mine had been blowing Fuse D, she did it three times, once pulling up to my house, second time pulling away from the petrol station and again today while parking up. Fuse D controls Dash, brake switches and diagnostic plug. It also seems to effect the indicators. Anyway, I the front brake switch was not working and was only tested a few weeks before so i suspected that. Sure enough the wire had got stuck under the tank and a wire had broken and was shorting when i fully locked the steering to the right. Easy fix and now i've routed the wires for easier movement. I've got a country if that makes a difference. The wires are really tights on mine and needed a bit of attention. Might be worth a quick look.
    Cheers for everyone who replied when i had my problem. Wiring is not my thing and this got me worried. I considered myself very lucky to just find a broken wire.
    Me and the bike have had words. She promises to behave herself in the future and I promise to clean her once in a while and not look at sports bikes so often....(when she's about).
