    suggestions please

    hey guys as you have most likely seen my other posts, i have a 96 blaster that i just got fired up today and idling perfect after 2 yrs of sitting. this is what i have done so far, but it still bogs when i hit the gas...
    cleaned carbs- they were nasty
    changed plugs
    removed gas tank and oil tank and cleaned both

    what i have not done yet is gotten a new fuel filter-

    my compression is also 120, 118- is this safe?

    it bogs instantly when given gas
    I think i need a tune up, but dealers are $$$

    Did you flush out the lines?

    Get a new fuel filter. See if that helps.

    If not, turn the high speed screws out say 1/8 turn and see what happens. May need more or less than 1/8. Can't tell without being there.

    Also, recheck your plugs. They may be gummed up with bad fuel.

    Glad to be of help.


    Use the stock Yamaha filter. Not sure where the best place to buy it is, maybe someone else here would know.

    You compression numbers are low, *compared to what most people say they have on a "stock" engine.

    *most people say that they have 150psi per cylinder.
    The Yamaha Service manual, which I have 2 sitting right here with me, states 134psi.

    I would say get a good gauge, borrow one if need be, and check it again.
    If you can, do it with a warm engine.
    Both plugs out.
    Throttle WFO and make sure if you have a choke it to is open fully.
    Fully charged battery, or use a jumper pack to make sure you spin the engine fast enough.
    4 revolutions should do it. 5 if you must.

    With them being that close to each other, I would say you are probably ok and it is just a low reading gauge.

    I have a Snap On Gauge, said to be one of the most accurate out there, and it reads higher than all cheap ones.

    Don't do as I did though and spend $200+ on the gauge set. If you really want a good one and don't want to spend that much cash, Matco has the same exact gauge for half that cost. Only difference is the name on the gauge. I learned this the hard ($) way.
