If ya cant redline your bike in 4th or 5th gear then you have either one or both of these things

1) your reed switch in the speedo needs to come out (dont cut the wires)

2)your exhaust is restricted in the front section,,,,,,take it off and look up it. there is a cone shape bit in it that needs to be cut out. Do this and you will have the ability to fully rev your bike and blow the balls out of it if ya want.

Read the rest of the link and do the rest of the stuff to if ya want but this much should make ya happy,,,,,,,,,YOU should also TELL your insurance company or your insurance will be void !

Only exhausts that have a number stamped on them 3MB-14610 will have the restrictor in them. If yours is that version take it off and have a look. While it's off check your PV is set up right, Turn key ON, after cleaning cycle check the slot in the pulley is aligned with the 4mm hole behind it...turn key OFF, then look in the exhaust port to see that the PV is flush with the top of the port.
