I feel like Shade now...... buy a bike, trick it out... and sell it.
Here's what I have. 2007 Honda CRF150R (pics coming soon). FULL BLOWN Fletchtrick race engine, engine mods alone were $5000. Ported and polish job, hot cam, high compression Wiseco piston, complete crank, stainless steel +1mm valves, heavy duty clutch springs, Dirt Digger clutch, new water pump, custom built (literally........... one off) oil cooler system with braided lines and a billet cooler, full suspension re-valve and re-spring by Promotion Suspension for a 170-190lb intermediate level rider, new bars and grips and starcross knobby. Since putting it together, about 20 minutes of ride time. Also comes with white plastic and custom JJW Designs graphics (best part

). Will come with your number of choice, of course.
Over $8500 invested, I'd like to get $5400 out of it. I can guarantee you this thing will knock your socks off. Will blow away almost any 150R out there.
This bike scares me, so I'm going to finish my XR100 build. :P :P :P
