    Noisy bottom end

    racking up mileage rapidly on the new FE570. searching the forums, it looks like the later models are fairly bulletproof (after sorting out fuel pumps, filters etc) so interested to see what kind of work FE570 owners have had to do after clocking up a lot of mileage. VALVES: most riders seem to...

    05 End Cap Mod

    I modded the stock end cap today. I enlarged the opening just a little. I have 2 650s , one with the Akrapovic an other stock exhaust. It feels like the Akra give me at least a few HP more and the stocker feels a little restrictive compared. So I wanted to give the stock exhaust a little more...
