    which would be better a sheet of high-temp or high-density gasket material ?
    I want to use it for both exhaust and intake gaskets

  2. High-Temp...especially out of Exhaust gasket.

    Use Gasket Sealer too...

    My 2 cents

    well, believe it or don't, after 600 miles i still have the original exhaust gasket (the trick is tight/tight/tight) & i've replaced my intake gasket with black fiber material (thin stuff) gooped up with permatex 1A, it's held up for over 200 miles now.

    I have been changing exhaust a bit trying to get a temporary one to work while waiting for my new pipe from Roland at spookytooth... but the bad welding job with an even worse welder broke while on the road and when I went to remove what was left 1/2 stuck to engine and 1/2 to flange. So, I figure might as well get a sheet for same price as single gasket and I should be set for a long time :)

    Some of these chinese motors have poor welding and heat distortion of the mounting flange on both the intake and exhaust. I ground mine down untill both were flat. I made my exhaust gasket from scraps of high temp exhuast gasket made by mr gasket. I also replaced the studs with high grade automotive studs. Finally, I used two stainless steel nuts per stud to attach the exhaust pipe. The stainless nuts don't rust like the steel ones do. They are easier to remove if you need to. Brass nuts would also work well.

    forgot to mention that my luck prolly has something to do with filing the flanges nice & flat.

    gasket material

    I had lots of trouble with these gaskets also. Two strokes get very very hot. Hotter than 4 strokes. My solution was to cut and drill a gasket out of a small sheet of soft aluminum.
  10. Since starting my new motor it would not idle and was bogging down down up to about half throtle.

    I remebered reading this from augidog and flatend my manifolds.

    This fixed it :razz:

    The intake gasket looked like it was ok but when I put a straight edge across the screw holes on the flange I could see plenty of sunshine where the hole is:shock:

    I then realised that the motor was getting far more air than it should have via the flange.

    Today I rode it and adjusted the mixture then it ran like a dream.

    Pulled well from idle (yes now it does!) through to top end.

    :grin: :grin: :grin:

    I did replace the gasket with a new home made one.

    Also replaced and flatend the exhast side.

    Has anyone tried to use the Permatex - Moto gasket maker? [​IMG] If you use soft aluminum to make your new gasket, do you put gasket sealer on it? When you file your intake manifold and the engine where the 2 butt up together. Are you just using a file? Do you finish it off with super fine sandpaper? Don't you want as smooth and flat of a surface as possible? I hope these questions are not too dumb. Thanks for the input. I am mainly looking for insight on what is best to replace my intake gasket, but I am thinking about what to replace the rest of my gaskets with. Thanks again

    magic goo

    i have 2 motors i have replaced both original gaskets with thick paper ones
    on one engine and used the original exhuast and replaced the inlet gasket with thick paper on the other.
    i had the same problen with flanges as Psuggmog so i flattened and ground
    i covered all my gaskets with
    LOCTITE No 3 aviation form-a-gasket
    and all have sealed great and no loose bolts make sure you cover around
    the inside of the hole in the gasket this will stop fuel/oil getting into the
    gasket giving it a much longer life i've used it on cars plenty of times
    and have always had good results there too can't recomend it highly enough
    for any gasket/sealing job :)
