Hey, turns out it was unseated float valves. Bikes been running like a bomb for the past week. However, while goin for a run about an hour ago all of a sudden the clocks died and the bike wont rev above approximately 4k rpm(estimate as clocks not working). Could this be the recifier?

Do the indicators work? most likely a blown fuse putting the bike into limp home mode. Check the rear brake switch wiring hasnt been touching the exhaust and shorted out.

These bikes have a limp home mode???

Check battery connections, earths, fuses (inc the one at the starter solenoid), check charging is ok.

If they cannot "see" the speedo then they are restricted to 5500 revs.

Yeah but ain't that just a speed restrictor rather than a limp mode?

You have a standard bike?

Standard intake and exhaust?

If so, you should be running 115 front and 118 rear I would say.

You have made it too rich :peace:
