G'day All. The seat on my XV535 is too low for me and I want to raise it by 10cm (the thickness of the two encyclopedias on which I sat, on the bike, which felt right). What I've decided to do it keep it simple: pull the seat apart and seperate the pan from the foam, mount the seat with it's plastic pan on the frame, as per normal, then built something 10cm high on top of the pan, then put the stock foam on top of that, and have it recovered. But what can I use to build up that 10cm? I know nothing about this sort of stuff - I'm thinking of something like, eg a sylicone, which I can get at a hardware and which will set hard enough to act as a 10cm high base for the foam - some sort of goo that goes hard like plastic. I'm concerned that just building it up with foam will create a vague mushy cushion. Any suggestions? Below is the bike as it is now, and further below is what it will look like with a raised seat. I will probably flatten it out a fair bit - both in terms of comfort and looks, I'm going less Harley and more road / brit bike with this.
