    New gaskets, always & everywhere. If the old ones come off fine keep them but use for emergencies only. Mind, o-rings may be used quite a few times, but you may want to have a spare one or two.



    JM2008 is on the button with water in the floatbowl. Clearly this man is experienced in this, and now don't go ask him how he knows it :lol3:lol3

    Change it for a new one or throw it away and don't put one back on.

    I pulled a cheatgrass seed out of my recently purchased CRF float bowl the other day. How that could work its way inside I have no idea, but I like running a filter, and carry an extra bec ause sometimes they break.

    Maybe the PO installed the grass seed as some performance mod???

    woohooooo:clap Cleaned my bike good for once, got rid of two pesky oil leaks, andddddddddd did a valve adjustment by using the method where you let one side go down and do the other, seems to be spot on so I wont be going back to the hassle of finding tdc, happy day.

    Sure sounds a lot like what happened to a buddy of mine recently. His ran like a champ then stuttered and stalled. kick, kick, kick, kick, kick, start........ then same. Fuel system, carb, hmmmmm......? Hey why not throw a new plug in...? It worked !!! Looking closely at his old plug, it appeared to have a few small cracks in the insulator. Cheap fix if it works.

    I've never been able to get that to work.. I fully understand it, but it seems to never get my valves right.

    Old post but great for people like me , if you're still around can you go on to the next part of taking the top off and replacing the usual parts (for dummies) because I'm pretty sure my right intake valve has seen better days. It is almost all the way backed up on the adjustment so much that I'm running out of adjustment which can only be bad right?. :eek1

    I've seen that happen on quite a few bikes.

    Flies in when filling gas. Not sure how it gets past the petcock filter but those things aren't very dependable.

    Actually, the last time that happened was in Guatemala when a guy I was traveling with had his KLR start acting up, sure enough a little seed of some sort stuck in his pilot jet.

    Hence the reason I run filters. Cheap insurance and never had an issue with the filter itself. I'm sure you guys are stick of me quoting mileage, but I've never had an issue of this sort running a filter, or had to service the filter itself.

    Couldn't help myself. Doing the Borynack fork mods. Hopefully it works. Waiting for seals and shims.

    I'm not against running a fuel filter, but when I do it's a big one that will pass fuel even if it's fuel of junk. I don't like those tiny metal mesh ones that people use, you can't see when it's clogged and it doesn't take much to clog it, just a few drops of water can clog it and you'll never see it.

    Big filters for me if I run them:

    When the happiness wears off from the fork tuning, do the shock and it will all come back again. I had to wait a couple years between doing the front and rear so that I could fully exploit my happiness.

    I think rebuilding the head is for the advanced students. I sent mine to XRSonly. Might as well make the valves bigger while you are at it.

    I wouldn't run one unless it was large and transparent as well. But beware, I did buy a filter at the local auto store and it broke the first time out; very brittle plastic. I would have had a long walk home had I not had some spare line, thanks to the freebees from Motion Pro at the Nevada 200 Trail Ride, which is coming up btw.

    Anyone going to be there? Nevada 200? Anyone?


    Also, those 90 degree filters can be handy for making the routing cleaner.

    You must be a bit more pro-active than myself. The fork mod happened due to a needed seal replacement. I rode that single -titted pig for quite a while before my back said, "do the rear, idiot."

    Had I known, I wouldn't have put it off.

    Larryboy,

    pls give a link to your build-thread of that Beemer? If you already did I missed it, and if you didn't create such a thread I'd feel less stupid but more surprised :lol3

    Top Overhaul Service for Noobies


    - Take tank & side-plastics off bike and clean all superbly
    - Load bike on loadbed of truck and secure properly
    - Drive to reputable bike workshop, unload and tell them to do a top overhaul

    That was 4fun :lol3


    Nope can do I'm afraid, too many traps with disastrous consequences if executed wrong. My best advice is to put your printed Service Manual (you do have this don't you?) on your toilet, and read from A to Z those parts which are applicable. Then, if still in doubt, read it all again, and then decide for yourself if you want to tackle this.
    Mind, if you work as neat as Mdlak does (check his pic of his forks above) then by all means give it a try, if you get stuck have it finished by a friend or the above mentioned workshop. However, I think one needs to understand the workings of a 4stroke like blindfolded, and if you cannot dream it then maybe reconsider the DIY route.

    If your adjusters are backed up all the way you better start making plans now, as yes indeed, that is a bad thing.
