Im just about out of ideas on my lost mid-range. I used to always stay even with or out pull my buds sx-r . Now he absolutly blows me away. Top end is near normal and low end is stump pulling, But what happenend to my mid? I have the usual mods w/ pipes.. also the cluthes run pretty warm....could it be the springs?.. Im running a 51/43 helix in sec and 8cr's w/ 14.5 rollers. all which are new along with bushings in primary cover. any ideas ? It feels like it wants to go but ..like ..there's somthing holding it back....the motor is running perfect at the rpm level too ..... I got about 15000 miles on her an still runnin strong!
