I am not a throttle maniac which helps with fuel mileage. both engines ran great and smooth. (any engine will run great if tuned correctly). I blew a rod on my picco ruffly a mth ago. and just blew my rod on my v-spec 2 weeks ago. I blame my fuel HAHA easy way outta that one... vspec had ruffly 5 gallons on it and the picco had just over 6 gallons. the reason for crankcase cracks was due to rod slop from the crank pin wearing bue to people not installing a new rod at the 1 gallon mark. o.s has revised the crankcase with more gap so no more cracking. every single engine should be tore down at the gallon mark for a new rod and bearings its just the nature of the beast. if you do this and seal the engines correctly you should have no tuning prbs. engines should run good yadda yadda yadda.. everyone has their own comments on threads like these you will get 100 diff. reviews. best of luck go with what you know and what your local hobby shop carrys
