misfire and no power above 5k rpm nc23

Post by willpisme » Sun Sep 02, 2012 10:51 am

hi, my nc23 is misfiring above 5k and has no power. I bypassed the fuel pump and ran a direct gravity feed which sorted it for a few miles but the problem has returned. The tank is also completly full and i have fitted a new battery. Plugs are all new and a good colour and sparking. Its a very intermitent problem and im completly lost on what it could be???!

Its your speed restriction kicking in, check your connections behind the clocks and give them all a good clean.

I meant to mention i had a gold CDI as well so no restriction. Turns out it was a dodgey HT lead on no 3 cylinder. runs like a dream now!
