Top Speed in each gear

[revhead]

totally understand what youve written but with the original motor ,i fitted a full titanium ARATA 4into1
bought from a local guy ,also at the same time i fitted a k&n air cleaner ,the improvements were immense , wheni got the donor bike it had the guts ripped out of the air box ,and had a yoshi 4into1 and the muffler was empty and the bike wouldnt rev past 7k in any gear ,now it revs to 10500rpm but is slowwwwwwwwwwwwwwwwww ,lol
