[QUOTE="Boozer, post: 198246, member: 25135"] i totally agree with the comment about spending money on riding education rather than on pipes and other go fast bits. If you must spend money, then go to a professional suspension tuner and have your bike set up for you, not the 'average' rider the manufacturer set it for. i originally had a FMF Powercore IV on my 250F and liked it alot. After a big accident, it was a total write-off. So i went and bought a R4 because the muffler is held onto the pipe with two springs so in the event of another big crash (flip it over at 90+km/h), the pipe should seperate from the muffler if needed. I fitted the R4 without the sprak arrestor (like my dealer told me. Why do i listen to my dealer??) and it ran awful compared to the FMF. So i went home and re-installed the spark arrestor and throttle response was better, and after some jetting tweaks, it ran not bad. But the FMF was heaps, heaps better, especially in throttle response and, funny you should mention it, the way it built revs. It sounded better too, as it had a tight, two stroke sound, whereas the R4 is a real RRROOORRRTTT, which sounds crap. If there is a Whitebros rep reading this, i would like to conclude that i am a very sad customer, and i miss my FMF very much! and before you ask, no, i can't afford to buy another FMF so ill have to wait until i buy a new bike, in a long, long time.:ugg: feeling all sad now [/QUOTE]
