Re: seat help
You can ... if it came with a low seat from factory you won't notice much of a change unless you modify your seat. If it came with a standard height seat you will notice a change ... and will also have to trim a bit of the body panel - but that's easy.
There are many options out there, and plenty of opinions here on the forum.
One other thing to check before you go spending lots of time and money is the seat height adjustment. It is the double bar plastic piece on the back/bottom of your seat that the latch goes over. You can loosen the bolts and adjust it there. Not sure if that will givve you all you need, but it is the easiest and cheapest thing to do first.
