Keihin FCR review on a SE 950

Wasn't sure what to expect but I needed to get some non CVs on here as the stutter/judder bump stalling was getting to be dangerous despite adding a fuel pressure regulator that controlled it to a large degree. I use my SE for off road 99% and always at race speeds. With harder use it would just lose all connectivity at the throttle to carb and blubber. Not good when you need a boost of power or are skimming whoops at 70.

First impression? Dead off idle to I'll guess about 2200-2500 RPM when it gets into a hit that might be a problem if you aren't ready for it. I guess I'll be covering the clutch a bit more in nasty slow stuff. The CVs with H2W prefiltered jetting were awesome in this regard, buttery smooth.

Mid is absurd now, and the top feels the same on the street. From my first street ride to just see how they are I know I could bald my rear Teraflex in under 60 seconds with the same throttle twists the CVs would tolerate. Should be fun, maybe not for everyone but fun regardless.

I'll post again after I get her off the tar.

Thanks to H2W for both my original CV jetting and a good deal on these FCRs!
