    hi
    i have just bought a husky sm610 1998 left kick (no battery) and i am just getting it road worthy but have a question please.(could be 1997 model spec as it was first registered jan 98')
    i am finding conflicting guidelines for the valve clearance on this model.
    i have a manual that says the inlet should be 0.004 and outlet 0.006..... but then found on a couple of websites that it should be set to 0.002 on both inlet and outlet . could some one please clarify this for me as i dont know what damage it will do if i do it to the wrong setting.
    cheers for any help offered.
    thanks

    On the E start models .002.
    On the k-start models .004 Int and .005 on the exh.
    to loose they beat the top of the valves up and ding up the adjuster tips.

    Thanks for the info Up-tite, but unfortunately for me, this contradicts motosportz mike's post, so dont know what to set to now..... it is set at 0.004 and 0.006 at the minute and not 0.005 on the exhaust. Will this do damage or can i leave it at 0.006. I have never had a four stroke before so a little unsure, just had "Yappy-Jappy" two strokes before this. I just want to get it right (well, absolutely bang on, to be honest.... I have to have things done right) and planning on starting it up at the weekend and getting out on it.
    cheers again.

    yes i have read it again but still it contradicts .... i am really sorry and dont mean to offend but i dont know who has the most experience between yourself and "motorsportz mike"... so my dilemma is, who do i go with? obviously its my choice and my mistake if i choose wrong and quite possibly a costly one, who knows?????
    i'll do a bit more research before i run it.
    thanks a lot for your quick response, cheers.

    When in doubt, I listen to George.

    The input you got was off by 0.001 on the exhaust. Personally I would consider either 0.005 or 0.006 close enough, but I have never worked on or owned that bike - George has quite probably worked on hundreds.

    +1 George helped me get my 410 running today, talked me through cam chain timing and valve check.

    thanks guys for the extra input and to George....

    sounds like George is "the man who can"
    I will double check and set to 0.005
    thanks again :thumbsup:
