1. The carbs on my GS 650 GZ Katana seem to have a small petrol leak (shown in the pic marked by the red arrows). This does not seem to affect the running of the bike yet, and they are still in balance and idle ok.
I don't know the first thing about bike mechanics. What needs to be replaced to fix this? Is there a gasket or something that needs replacing?
Is it a major job? Do the carbs have to be removed from the bike to do this?

2. The Helmet lock is broken. It's not now possible to clip the lock shut, the hooks just flick open again. Is there a way of fixing this or will I have to purchase a new lock and hence have to carry an extra key all the time?

Thanks in advance for any advice/info.
