2009 GS500F won't idle

[The Buddha]

You're in New Zealand - I dunno you have a place like Kibblewhite etc who sells high quality valves ?
I don't know what these things cost over there. But I would be pretty happy just swapping the head gasket if that's the only issue - you have 43K - its due for cyl/rings/head, but how easily can you get these over there. That would determine it IMHO.

In NC/SC area US, I am surrounded by Nascar mechanics. I have easy access to the best parts and mechanics on the freaking planet all in a matter of miles from my door. I'd do the whole thing, but well, if nothing was easily available, I'd be reluctant to put in that much $$$ into a bike I haven't ridden to know what its actual issues are all there.

Cool.

Thanks for the replies, I would like to do full top end rebuild but honestly I don't think it's worth it if I don't need it. Mainly because you can't by any new parts for gs500 over here and I have to import everything including head gasket. Secondly, I want to break even on what the bike owes me. We have no stores like kibblewhite but I did see that brand of valve on ebay, so if I have to I'll buy those.
