fmf power core IV-2 test

3 posts in this topic

I purchased the new squared pipe and gave it a test downthe street (I have a plate). The first thing you need to know is it's really loud. Hell, it sounds like the race bikes at Carlsbad Raceway. It's at least 20% louder than the super trapp pipes on my XL 500 and XR 600 (each with eight discs).

I feel sorry for my neighbors, not to mention what happens when I cruise it on the street or in the National Forest. I think

FMF really overstated how quiet the new square pipe was going to be. Too bad somebody doesn't make a pipe with an adjustable gate (like the old honda 305's). Then we could cut the noise when passing sensitive ears.

Anyway, the bike feels quicker. Prior to, I had a Canadian pipe with no throttle restriction or air box lid. Mid range was noticably stronger. Or maybe race bark of the pipe just makes me think it's quicker.

I haven't rejetted it yet, but will do so this weekend. I should be able to give you better feedback next week.

Encinitas,

Please don't compare the WR to the XRs, sound wise. The increased compression, number of valves and RPMs of the WR make it a VERY hard bike to silence.

I think we will all be disappointed in FMF if their claims aren’t substantiated. I was afraid the ads were heavy marketing, but held out hoping for better technology.

Thanks for the news! Let us know how things go after jetting and your first off-road miles.

Jake
