Aaen pipes, 49/45 helix with green spring set at 80, primary has 8dn10 with 4.5 in tip and 3.1 inner red spring. It pulls real hard but over revs slightly.
Max RPM I get is about 9300. Should I change the 3.1 to 4.5. If I use my Y-G-Y spring it is even worse then the red. I am so close and just not sure how to get the last little bit out of her. Someone suggested to change gearing.
I have reed spacers, middle layer removed from head gasket, SRX rear heat exchanger and stock gearing.

Change The 4.5 Tip To A 5.5 Nut And Bolt.

where would I find 5.5 nut and bolt. Does Yamaha make them?
