Reply To: Bike start’s but revs to 6k after upgrades.
However even though the bike is running so much better it has a flat spot between 4k and 5k rpm, any Idea as to what could be causing this. !!!
Pilot Jets or Slide Needle too rich / too lean (you want to be in middle or just slightly rich due to having extra grooves compared to a factory needle that only has 3 which means its longer needle than factory) ,
like before above comments also, i mentioned plug check, you’ve still yet to report that. We have to see it.
