    A Few ATC 90 Questions - Another Question

    I've recently purchased a 1974 Honda ATC 90 for $20, so you know it needs a bit of work, and I've got a few questions.

    #1: What carbs of other machines will fit this? I haven't got one.

    #2: The oil dipstick was missing when I got it, so I put in the one from my 200e parts motor. Will this dipstick give the correct oil reading?

    #3: There are no tires or rims. The rear hubs are 3-bolt, while the front is 4-bolt. What rims of other machines will fit this? Possibly with a change of the rear hubs to 4-bolt.

    Any help would be great.

    If you use a 110 carb and intake, it will work.
    You need the dipstick from a 90/110.
    No one can guess what front hub you have, but it's most likely a 4x130. You can use the rear hubs off a 200x if you want and have 200x rear rims, they are 4x110. You can use the front hub off an atc90/early atc110/early 250r/early 185s for the 3x100 bolt pattern. Or you could use the hubs off a later model atc110 to get the 4x130 bolt pattern or you could use hubs off a later 185s/200s to get the 4x130 bolt pattern.

    I did a search for the carb, and couldn't find anything, and I didn't know what to search for the rims. With the 110 carb, I need the 110 intake also, because I have the 90 intake.

    The problem I'm having now is that the piece that holds the intake rocker arm in place will not move. The one for the exhaust slid out very easily. I have sprayed on some penetrating oil and let it soak, but it still won't move. Does anyone have any tips that might help me get it out?

    if i remeber right, you can push them out from the other side.

    if not i think you can thread a bolt into the shaft and get a better hold of it.

    No, I can't get to the intake one from the other side. What size bolt should I use?

    If the splines on the hub of a 185/200s are anything like the ones on the ones on my 200m, they will not fit.
