Hello there I have a 1985 gpz900 project bike . I need new fasteners for the float bowls as most of the originals have stripped heads . I was to change them over to Allen screws and was wondering what size and thread type I need? Also I am changing the jets to 1.36mm mains because the previous owner installed carb pods and it runs like Shite. Where can I buy jets without paying for the expensive jet kit like the one offered by Dyno Jet . I just want to buy individual jets .
