Don't be shocked on the investment tag $ 17,250.00.
I am looking for some one to make a very reasonable offer. If you have some XS 650 ( 75- kit raicng sleeves, ignition etc) racing stuff to trade in we can talk. I can't race any more. Hoping this will be done up for the track. there are many stock Gamma parts that come with it as well.
Looking for around 14,900.00 OBO
