I continue to tweak "The Unicorn". I've learned a lot this year after doing some more modifications. Three things have really made this bike awesome for me:
1) I ditched the stock subframe and built a seat that bolts directly to the tunnel frame. This lowered the seat a bunch and put it at a better angle.
2) Added a set of pegs behind the chain case. This puts me more in the center of the bike which I think is crucial for the long track. They are an inch or so lower than the stock pegs.
3) Built a custom bar riser that brought the bars up a bit and back about 8 to 10". This accommodates the rearward riding position.
For me, this was a total game changer. I now stand up almost all of the time in a very comfortable stance. This really distributed the weight much more evenly. So much so that I had to ditch the fat ski because I was getting too much float!
This has worked out so well that I am going to build up my 950 Super Enduro with the same type of set up.
