^ it does kinda, but I never mess with these contraptions more than to set them to run at stock specs or vry minor mods, and I have to say I have never had a head gasket failure on any of the countless mopeds I have owned over the yrs, not to say it can't happen, but I don't worry about it. Do you find a good seal when you delete the gasket or do you have to smooth the head/jug to get a good mating surface?
