I have a 81 SRX and used a v-max crank in it with srx stator and flywheel. I was wondering how to fab a whole in the frame to put the torque bolt that my v-max has. I think they put this on as an update but not sure....Also i have the single fuel pump that the srx 440 uses but the v-max crank has 2 lines coming from the crank, i was thinking about having 2 lines join into one, to the fuel pump. Or should i just plug one. Also im not running the oil injection and just going to run mix gas in it, the oil injection system is still on the motor minus the oil can and lines, should i plug them or just leave them??
 

i dont think the pulses will be right if you connect the lines together... i believe they will counteract each other and actually not pump any gas... just use one and tap and thread a bolt into the crankcase with locktite where the other hole was... you want to make damn sure that doesnt leak air or you will be buying a piston....
