Thanks Phil. I actually took some rubber car floor mats and cut those out of that a few years back. Basically I just followed the shape of the knee indent area of the gas tank and recessed it about an inch back from that all around and from the bottom of the tank.
And re the center stand. I know what you mean about this issue. I haven't mentioned the following before, but yeah, I did run into a similar issue with mine when I was bolting it up.
What I did to get it to swing forward enough was to take my bench grinder and ground down the two little stopping "nubs" about 1/16 inch or so along the side of 'em that swing along the bottom of the bike's frame rail. That allowed the stand to swing a little more forward before the those nubs land up against that section of the frame rail.
There still appears to be plenty enough of those nubs left to be strong and sturdy enough to support the whole structure whenever the stand is being engaged.
I do think an alternate plan might be to slightly grind down the bottom and back corner of that frame rail mounting area enough to allow those nubs to engage further forward.
Yeah, it does seem a slight shame that one has to do this to get these stands to work perfectly, but I've just chalked this all up in the "Minor/Personal Preference Adjustment" column.
