I know what you mean man. The hose I'm renting is "worth" 170 in a down market. There is no way in hell I would pay that to live here. House is small and has a small yard. Thank God I can transfer back to Ohio where land and homes are dirt cheap.
if you can get about 3grand to spend on your banshee right now it will be cheaper for you in the long run. I have a serval and its the shit for trail riding so you could look into that. Lots of site sponsors sell them in "kits" they come with everything you need to build it.
I would trade you everything you traded me. Cylinders, cool head, 24cc domes, pistons, only thing that wouldn't come with would be my intakes and reeds. I would need to sell those to get some for the cheetah.
I believe the spacer plate is used to correct the port timings for the added stroke. If your getting your cylinders ported for the 4 mil crank just get a cool head and cut domes.
