I just got a ‘79 NF75 pop and a few rides in it collapsed a drive bearing. So I’ve fixed it up but now it tops out at 45kmh and kind of pulses power when full throttle, feels like it’s trying to go faster but is being restricted somehow.
The carbs got a stock 92 main jet and everything else is stock too, any ideas on getting more oomph out of it? Surely it should happily cruise along at 70-80kms
Any help appreciated,
