I need a couple of carb parts that dont seem to be listed on the parts lists and drawings on CSMNL, The 2 parts i need are,
Locating dowel's between the carb base plate and carbs
Screws that hold the butterflys in place
Anyone know if these are available from honda or will i need to go to Keihin?

I don't think either are available from honda, they probably come pre-assembled.
The screws don't like to be reused, they have a split/flange in the end to stop them working loose, and usually wreck the thread when removed. Whatever you put back in there make sure to use some serious threadlock!

If you use the wrong type of screwdriver they'll strip.
There JIS screws, you need a JIS sized screwdriver to remove and reinsert them without stripping them.
I've removed and reused the screws many times.
I've also had bikes where people have knackered almost every screw using the wrong type of drivers.

It's a Japanese standard size, as opposed to our standard sizes.

So how does it prevent stripping the THREAD? Just to clarify im not having issues rounding off the screw head or removing them, it seems these screws are a 1 time use only hence why the thread strips (sometimes) on removal.

, but the heads of the screws them selfs as there buggers , as you only got to use the slightly wronge size screwdriver might seem like it fits and then strip gos the head , , as for jis screwdriver dont know , i use pozi screwdrivers my self ,

The screws are peended over at the end, that's why they strip. They're not made to be removed!
I think replacement screws in the same size and some good threadlocker would be the easiest solution.
