Proud owner 93 Katana 750.
Running a V&H SSR2 full exhaust system a Factory Pro stage 3 jet kit & K&N air filter. Dyno was 100 hp last season and she ran great.
Dropped in a new set set of GsxR 750 cams and she ran even better, however needed tunned in a bit.
Ok, so I took her back to local shop that installed the jet kit & dyno tunned her last season and here's the big issue. Got her back and runs like Sh%t !!! around 93 hp w/a giant hole in my mid-range!
Starts and runs great until gets to 6-7+ grand, missing and surging sounds really fat, add some throttle and the r's drop baddly, but once she pulls out and above 8 grand or so she comes back to life. The shop can't get the bad spot out infact it's way worse than it was before I took her in to get dyno tunned.
The shop said they dropped the needles all the way down took out plastic spacers on the needles played w/air fuel and basically gave up!! Really need tunning advice.
CP.. someone anyone please!
