Going to look at a 2006 supercharged Apex no reverse it has a 280hp MPI supercharger (planning to lower boost to 10 psi-240hp) has head shim, Has boost-air/fuel and charger temp guages, bar riser, main guage relocation, lightweight aluminum drop brackets, mountain mod lightweight seat, flat top tunnel mod+tunnel lightening, lightweight gas rack, camoplast challenger extreme 2.5" track, custom under tunnel lightweight exhaust, AVID exrovert drivers, lightweight mesh hood, and was professionally built by dealer. What should i know or maybe look out for? Has about 800kms. This will be my first 4 stroke. Ive heard some bad things about SC and just wondering if ill regret it over a turbo? I ride 3500-8000 altitude and want a good reliable boondocking/ Climbing sled. Do they really feel that heavy? Any advice would be great thanks.
