    hey dudes. i bought a 97 gsx a while back, finally got around to cleaning it up, cleaned up the carbs and ready to drop an engine in it. it had a coffman pipe on it with a solas sc x1 prop. what are the stock jetting and needle sizes? it has 142.9hs wit 2.0 n&s. also both carbs has a fuel pump . should i remove the second fuel pump? i want to go back to stock. thanks. also what rpms is it supposed to turn up?

    142.5 mains and 70 pilot, it comes stock with 1.5 N&S it looks like it was jetted for an aftermarket air filter and the coffman pipe.
