You'll need new studs and and maybe new nuts depending on their condition. M6 is the size you need. Mine snapped a couple of months ago too and instead of using studs and nuts I've used standard hex head M6 bolts. Much cheaper and can be easily replace with a new one when it gets slightly corroded. Don't forget to use a dab of copper slip.

I got 8 studs and 8 nuts from my local Honda tippets for under £30.
The studs are cheap but nuts are a bit pricey for what they are.

Use cheap stud at your own risk. I did that and ended up with half the studs threaded and half snapped, which cost me another £100 and a day's labour to remove the engine and take it to a specialist who could sort the threads. Replace with OE parts or be a rectangular thyng!

Personally, i always use stainless stud and nuts, or just buy some long stainless bolts and cut the heads off. And deffo use plenty of cepper grease. I've been using stainless for over 20years and never had a problem.

The nc30 microfiche is on akhara.com (Daves nc30 page)

just click the link to the parts manual and you can see all the part numbers for the whole bike.

Once you have the part number either goto lings.com or davidsilverspares.co.uk and put it in there and it will let you buy it.

or if you have a local bike shop / honda dealer you can go there and ask them to order

they are exhaust studs - you need to get some coppergrease (copaslip) for when you fit them to stop them seizing in the head again.
