What are pros and cons of deleting acc pump and rejeting

His specs are for a 97.5 white pipe. I'd run 165 highs with the stock black pipe.
Those filters allow water ingestion a lot easier and that is the root of many 951 failures. If you can keep water out then the ski will run better and there won't be any accel pump to fail. The larger low speed jets help with the 3/4 throttle lean spot that 951's have(some say they do and others say they don't but might as well be on the safe side.
