Default Re: ngk spark plug for slant head

Yes Greg your 100% correct in fact before i put in the second gasket I was getting blow by out of the single gasket when I swapped to angle head because of to much compression.
However when I put in the second gasket "Even though one would think this will not fix your blowout issue " it did & the only reason it did was because " like you stated Greg "it lowered the compression" & stopped all that black oil from getting all over my bike and my legs
