    help....valve adjust question

    anyone adjust their valves on the ltz250 ?

    I got the plastics and the gas tank off, got it to top dead center
    removed the intake/exhaust cover nuts to access the adjustment
    screws but .........................

    I cant even get the angled feeler guage in there

    I have searched the net for a service manual, either online or to purchase but no luck (surely they make one ?)

    it dont look too hard to understand, just a screw with a jam-nut
    open it to spec and tighten back down but I cant get a guage in there...............................

    what am I doing wrong ?

    I dont want to drag it 45min to the suzuki dealer
    thanks

    I figured it out,

    had to remove all the plastic and the gas tank

    set the motor to top dead center

    there are two removable access covers
    (one for intake and one for exhaust)

    under each is a small screw with a jamb nut, loosen the nut and turn the screw to set, then hold screw and tighten the nut

    while I had everything uncovered I pulled the carb off and cleaned every jet/orfic then put it back together

    it runs ALOT better............... time for some tires now

    next time I adjust them, ill take pictures and add directions
    so the next green-horn like me will have a clue

    I did have to bend a set of feelers to get it into the very tight spot

    no gaskets or anything where needed

    Thumbs up LTZ 250 service manuals..I know where to get them

    I know where to get these shop manuals for 1/2 of what ebay's selling them for. Go to sell.com and search for suzuki service manuals..a seller has them just like the dealers...$35.00 out the door! Hope this helps since this particular manual is very hard to come by...as with ay info for service on these bikes.

    thanks for the info, I will check the site for sure

    this post is almost a year old, I have upgraded the little zuki into an '06 yfz450 (but I need a service manual for it also)

    thanks again
