Curious if anyone is running a Calsci shield on their F3/F3S machine? I'm considering their 18" (shorty) dark tint, but it appears Calsci takes measurements of their shield lengths versus shield heights. Many mfrs measure their shield height in a vertical line up from the fuel cap > tip of the shield. In this measurement, I'm wondering how tall the 18" model is? Heck, if you have a 22"/24", I can at least get a ballpark idea. Thx for any info..
