Hi all,
I bought new fuel tap kit (NC21 1987) few years ago after some reading on this message board. Recently I've noticed that the tap is leaking fuel so i took it apart and noticed that there is a small hole in the rubber. I think it might have been caused by shi**y EU fuel that contains some Bio additives. I had problems with fuel in the past because the bike is not running that ofter and after each winter i have to drain the carbs. I can tell the fuel has gone bad just by smelling it. The fuel tap kit was around 20GBP not including the shipping fee so the question is where can I find a tap kit that will be resistant to ethanol or whatever chemical they put in the fuel. Also do you think that shell v-power hight octane fuel will not degrade as much as the "regular" natural 95?

Greetings to all V4 riders (especially from Czech Republic )

high octane fuels often have more ethanol in them as it increases the octane cheaper.

id stick with regular unleaded.

I dont know anybody doing a tap kit at the moment.

LiteTek on here makes many replacement carb gaskets in ethanol resistant Viton rubber.

His website is here.. I don't believe he currently makes fuel tap diaphrams but I think he would be my first port of call to about ethanol resistant rubber parts.. send him a message and see what he says.

Try NRP carb parts in the UK.
They list NC21 tap kit.
