I am in the proccess of rebuilding a new 49cc motor with headkit, crank ect. I was wondering about gasket sealer. i have heard you are ment to put the head on DRY is this true? and is it the same for the cylinder? Also i have some Permatex gasket maker red silicone that i was going use but i noticed on the back label it said not reccomended for parts in contact with petrol. So what should i use?

permatex ultra blue for crank cases and cylinder base gaskets wont be effected by petrol the red is great for exhausts gaskets works well with high temps

Sweet cheers mate! But do you put put the head gasket on dry? thought this made sense due to setting squish ect thanks.

i like the permatex aviation sealer. the brown disgusting looking stuff. I didnt have any luck using the blue hylomar or the hardening cement sealer. probably using it wrong.. but none the less ;p

yeah the head gasket goes on dry. only need that little copper ring it comes with. if its a cag.
