I fired up my 426 to let it warm up (doesn't get ridden that often), and found that the petcock is leaking externally when on. Is it likely the seal, or is there something else I need to look at replacing too?

Yeah, there is a couple of pieces of rubber in there that go bad

After mine was stood unused whilst away working for 5 month I had same problem. Turn petcock off after few mins of leakage and when returned next day it didn't leak just dryed out rubbers when coated in fuel worked again. But I changed rubbers to be sure. The old 1s weren't perished at all.

Mine sat 3 weeks, so not all that long. 

 

Is OEM the way to go for new rubber?

Oem Always best way but I just used from pack I have in lock up. Full pack bought from eBay for £5.99 but won't ever need any o rings seals etc as pack is 650 pieces.

In case I didn't make it clear, it was dripping externally when I turned it on. It's possible that it's leaking internally as well, I don't know, but if so it isn't enough for the bike to idle on (I like to let it run to use up most of the gas in the bowl and then drain the last bit)

we had pools of fuel ontop of engine cases pooling around the base head gasket area it was dripping straight from the tap when turned on. But stopped when turned off.

If you want my two cents, spend $15 and replace the whole thing.  IMO, you don't have more than a 60% chance the new seals will fix the thing, and you'll end up replacing it anyway.

Is there a reasonable aftermarket one? Retail for OEM is $60ish.
