Is anyone else having problems with the ethanol in the gas making the clear windows real soft ? they look like they are almost disolving them, i can't remove them because they are so soft that the outer part twists off from the threaded part. I plan on putting brass plugs in there

I have run into it as well, not sure if it's the alcohol or just gas breaks the stuff down over time, I could not see in them very well anyway....replaced with the stock plugs....Rob
