Nice one Tony, I can see in a nutshell that you would greatly benefit from a seat reshaping, if you get someone to unstitch the vinyl cover and remove the "hump" you will then get a lower riding position, much greater confidence off road when the bike goes sideways as you would have feet ready to be planted on the ground and, all you need to do for the front is to lower the the fork legs distance by adjusting the yoke to your required meaurement.

Then apply the "Law of Kev-relativity" i.e. heavier grade oil in the fork and set of spacers will make the action perfect for your requirements. I would have suggested a set of high performance coil springs such as ohlins but you don't want to mod it too much. Yet springs and seat can be easily and quite cheaply returned to original.
