I have just gone through an entire engine teardown after a ring caught the exhaust port on the PTO side cylinder of my twin 600 SX. I have bled the oil pump and made sure I had oil prior to starting it up the first time. I also have a 50:1 mixture in the gas tank itself. The question I have is, how should I set my oil pump. I know how to adjust the oil pump, but everything i have read says to check the gap at the cable adjustment. I noticed I have two score marks on the top of my oil pump arm that the cable goes to. I have one mark at idle throttle position and one at WOT. I have set the oil pump cable to be right on these marks at both positions. I bought this sled used so I do not know if these marks were put on by the previous owner or are factory. I want to error on the side of being too rich than too lean and loose a piston in the process. My 98 600 SX has been jetted, boysen reeds, and piped. Will any of these effect where the position needs to be set on the oil pump? If so how do I know where to set it. Please help so I don't ruin an engine. Thanks
