    On a later case with a rectangular breather port, you need do nothing for an 80cu.in. motor. You can square up the hole a little so that the inboard and outboard edges match the gear (like matching intake ports). The actual timing is usually generous for a stocker or small stroker.

    Use a steel breather gear! HD or S&S recommended.

    S&S has a few bells and whistles over the stock gear ...

    Note;

    The S&S gears has added open timing built in ...
    With that, less case window grinding is needed to dial in ...

    What is the preferred way to check valve to valve clearance on a Shovelhead?

    Is there an easy way to do this?

    Right now.. Dragging an allen wrench through the spark plug hole appears to be as good as anything?

    Yep, there you go, or a piece of wire the diameter you need. You have to rock the motor a few degrees around TDC to find where the valves get closest.

    Cam specs will show the TDC lifts .....

    From the valves off seat to those specs and held there, will be able to see how much distance there will be between the valves....

    Think the engine is ready to go together for real.. Thanks for everyone who helped.



    Looking at the transmission now.

    It is a cowpie. The rotating shifter plate in the top is pretty loose. It wiggles a lot.

    Is there a standard fix for this, or is it not a big deal?

    Should I try to bore and bush it? Bronze or make a sleeve out of something like stainless? Delrin?

    What do you do with these things, if anything?

    Surprisingly, it doesn't seem to get a lot of lubrication up there.. Rusted springs. Debris from those not washed out and down into the transmission case, where you would expect to find it. Etc.

    PS: Anyone happen to know the stock rake angle for an 80 FXEF?

    I measure about 30 degrees?

    As far as I know all the four speed swingarm frames have 30 degree necks.

    You can check the clearance, but I find the plates rock a good bit with minimal clearance at the shaft. Bronze would be the bushing material of choice if you go that route.

    Thank you..

    I think I'll try and do something with it. There's about .020+ at the top, and about double or triple that underneath, where the plate goes it. It's wearing bell mouth really bad there. It's just really loose.

    I ordered a boring head for the mini mill and I think I'll try and make a sleeve for it.
