Post by anderoo »

Hi . my nc30 struggles to do 95mph, its got the speedo deristrictor fitted, jets 118, 120. ive fitted a new air filter and its got a race can fitted. the bike revs freely round to the red line but seems lacking in power. any ideas

Fuel line collapsing when it gets hot and is drawing max fuel flow perhaps, or vacume tube?

That is usually an indication of it running lean. Is the airbox complete?

Where you based? What riding you doing?

You didn't buy it off a dude called Hamster did you? :whistle:

sorted nc 30 other week. took it to a bike mechanic to have a listen to it running,said it sounded a bit lumpy. did a heat test on all four exhaust pipes and discovered one cylinder was down,not firing. put new plug in runs like a dream.
