89SRV

hey,
im new here, i ride quads and just bought a 1989 Yamaha SRV 540. it huals @ss, for as old as it is. but it had never been rebuilt so this summer i decided to tear the top end down. it still ran, but the one clyinder and piston where scored really bad but the other one next to the fan was fine. i figured b/c that one stayed cooler then the other one b/c it is right next to the fan instead of the clutch which heats up. so it had to be bored .020 over and got new wesico pistons and cometic gaskets(same as my quad )

so, when it was apart i was looking at the oil injection. i have decided to take it off and run premix with the new top end. i have a few questions. 1.what is the ratio of the stock oil injection? 2. what should i mix at now? i mix my blaster at 32:1 but i didnt know what ratio since its colder and everything. 3. can i take off the pump everything else, and then take everything out of the pump and put it back on to act as a block off plate? and then of coure take off the tank and lines.

Thanks everyone for your help. Jason
