    How much squish band clearance is everyone running? I'm thinking about 1.0mm at say sea level is where it should be.

    What about head and base gaskets thickness stock? Any options?
    How about custom copper gaskets in different thicknesses.

    We're going to need the year make and model, also I don't think Husqvarnas use a head gasket unless their water cooled.

    Haha, sorry it did not correlate to my instinks. I only have ac models(except for street), but lots of these fellas have LC bikes. I had an 82 Honda 250r that required .7mm to keep the piston off the gasket I never figured out why til years later(circa 1993). To prevent the failure of their crappy gaskets, but I am sure the newer gaskets are superior. I put an old used copper gasket back into a 1955 Kohler Generator and it has been wonderful, albeit only a year or so with little usage. Check out my vids top see it in operation. One of my proudest builds. Good luck toolie! Chris

    1.0mm is a good starting point. I have had Cometic make base gaskets in many thicknesses for the AC bikes.

    Great, thanks.

    I'm not sure what current clearance is but I'd like to go in steps just to be on the safe side. The piston was replaced when I bought the bike and being an aftermarket piece it might be off. Just a feeling, compression seems a bit low.

    It is probably about 1.5mm stock. But ya, go down in steps and see what you feel. Contact Chris Workman at Cometic.
