Crower sells a sleeved cylinder, a piston, gasket kit and a cam for %1,499.00. Is it me or is that price pretty far off from the rest of the market? An Athena kit and an 08 camshaft will cost $700 less for example and for $100 ove the Athena kit you get the ICECUBE. Additionally the Athena and ICECUBE have larger cooling pasages and do not use sleeves since as I understand it from my 2 stroke days, a steele sleeve will inhibit heat transfer to the cooling system. Does anybody have experience with the Crower kit? Is it worth $500-$700 more than a billit ICECUBE 276 jug or Athena kit with a new stock 08 cam for example? I am pretty sure I am missing something. Anybody?
