My 18 has been a belt eater. Stock tune. MTX weights loaded with heavy rivets in all locations. I put high torque secondary rollers in, Dalton 35* billet helix, black/orange spring. Primary spring broke and put a black/bronze in there because that’s all I could get in a short timeframe. I’ve had primary roller bushings slide out and cause the roller to bind, so am always checking those. I had a dealer go through it at the start of the season and they machined off some of the secondary(3mm iirc). To bring alignment into spec. Does anybody have any measurements on the factory solid spacer for the secondary, even with 3.5mm shims I can’t get the belt to even come close to the top of the sheaves setting deflection. Use 8JP belts. Belts just explode, have went through 6 belts in 1600km. Thanks for any help
