Cheers Paul. I ordered some from Saisei-Europe shop, they are
also Viton one's made by PMC (in Japan). I'm hoping they'll be
delivered soon so I can get me engine re-assembled before xmas.
Anyway, point is, has anyone else tried the PMC one's, they too
are pricey, but I'm interested to see how many miles they'll
last? If they're no more durable than the SuzukiPerformanceSpares
Viton one's, then I'll buy their one's next. As a side note, as Rob said
in another thread about Valve Stem Seals,
"Any "Viton" seals if installed correctly should last equally long."
