Got pissed as I wait for my new seat and decided WTF - not gonna keep the old seat - lets rip her up - peeled off the vinyl - breadknife to the foam and glued er back on - dropped the seat height 2" .
Kept some extra in the front for the boys and narrowed it down a lot in the front 1/2- left the back for the fat ass the same.
Yeah I know - did the whole thing in 1/2 an hour off and back on and I know I could have stretched it tighter but couldnt be bothered.
That said - not that hard to do BUT - as I said the breadknife cuts the dense foam pretty easily -it doesnt leave it all that smooth - SO if you want it tight and smooth then you will have to use - don't know - hot knife maybe - or another layer underneath the vinyl.
Be careful NOT to cut the vinyl or rip it when peeling it off the seat pan and go for it.
IF I was leaving this one on I would make it more purdy!
