Here you are RA.

It gives you a rough idea how to set the float height.

I can never remember if their 5mm or 6mm thread.

You can use these or get some brass ones from Morgan carbtune.

WELDING TIPS
Bit of advice. Buy a good bed and a good pair of shoes, because if you aren't in one you'll be in the other.

FZ engine here has 6mm bolts. 1000 Genesis engine is the same so I can't see exup being different.
Genius idea with the welding tips! I would be tempted to drill the hole out in them. 0.8mm seems a bit puny to me?

Yes you can drill a larger hole if needed and I'd put a bit of silicone sealant on the thread (making sure you don't get any in the hole) to help it seal to the manifold better. :nod:

Did you get it sorted? My old Thunderace had a similar problem, and eventually traced it down to the choke springs being weak, so not closing off properly and letting fuel piss in

yes thank you for asking

"I also clamped the float seal down as suggested. I actually think that might be the culprit and the far right carb one was not as tight as the others. But it could have been the float height as well

Put the carb back on the bike and started her up and blipped the throttle a few times and no leaks. I had to set the idle by ear as my tachometer doesn't have numbers on it just a bar. let it run for about 20mins still no leaks.

So I took her out for a spin and she runs well, I will still probably have to balance everything at some stage so its smooth. "
