Hi all, after 3 years my nc24 is done, many new and recon bits, and I think it look 'la nads du chien' but I have a problem ! a misfire at 7k that clears at about 8.5k and pulls well to the red, anyone got any thoughts ?
plugs are good, carbs clean and balanced, vacuum pipe to fuel tap is good, me thinking coil on way out or ht leads?

While some here sort the problems how about the rest of us get a chance to look at your effort?

I will put some pics up as soon as I get the plastics back on

That is the transition area from needles to main jets.

The carb internetals in the right place? what jets is it running. what exhsut system

thanks neo

I think main jets are 115, standard exhaust apart from collector box I knocked this up in stainless but copied the old one and is within 2-3mm of old one, I have however noticed some 'scratches' on the vacuum slide things could this affect things ?

could it be the needle heights maybe a little rich ?? my fzr 400 would bog and splutter at higher revs until i dropped the needles by one notch.
