NC23 Carb Synchronisation screws - alternatives??
Looking for the screw that adjusts the carb synchronisation between the two pairs of carbs. For some reason it is totally missing on my bike!
Any ideas
or does anyone have one? Also does it have washers etc??
My garage is looking to get one imported from Japan, but that is going to take atleast a month
!
I am desperate to get her running smoothly!!!

Odds are it's a 4x6 pan head screw, bog standard and nothing special.
I'd actually recommend to get yourself on eBay and replace with stainless, maybe allen bolts as this allows you to adjust without leaning on the head, which can distort the reading. If it's totally missing then it could have threaded and fallen out?
In any case it's worth putting a dab of mid strength thread lock on the screw so that it dries out by the time you've got everything set right, otherwise the screws can vibrate looser and upset the balance again.
