was just wondering if the is any jet kits out there available for the nc23?
or any other kind of tuneing?

Your probably going to be better off trying to find someone on here who has jetted a nc23 and find out what jets, needles and adjustments you need.

It will depend on if the engine is standard or not, exhaust and air filter..

Probably best speaking to either Graham France or Stimpy?

Just get it done on a dyno. They will fit honda jets to suit whatever mods you have on the bike. Dynojet is a name like Dainese where you pay a premium for something that you can get half price

out of interest what mods have you done to bike, when i had mine i just changed the standard 105's to 108 dynojets jets and it was spot on with the race can, when i changed to full system, modded head and race cams the only change needed was to lower the needles, it meant drilling the carb slides out to lower the needles to avoid buying fancy needles that were virtually non existent.

dyno proved this to work in both situations

I have some 108's if you want them?

ahhh right interesting,
erm the only mod its got is the can its an mtc but ive chopped it down to 8 and half inch will this make a difference if i jet it?

ooooooo woodzy i might be interested if it makes my performance better, what do you want for them mate?

You can have 4 108's for £14 posted?

petrolhead just to check, yours is a '89 K model yeah?
IIRC J and K models have different standard jet sizes, K being the 105.

Also thanks to brooky for the info, pretty much answers what jet sizes I will need!

yeah wozza mines 89' k model mate
last time i had the carbs off they were 105's on i remember that much lol

sounds good to me mate you want the money via paypal? pm me bud

just one thing to bear in mind is 108 dyno jets are supposed to be the equivelent to standard 110's.
