Anybody got a known York A/C compressor for a 4kcsq? Anyone tried Michelin MXV4 (V rating)195-60x14 tires on 4kcsq? My tire guys says that sidewalls are stiffer and rubber compound is softer and no mileage guarantee. Are the tradeoffs worth it? Michael Conley bikeaudi@aol.com 92 S-4, 86 4KCSQ, 874KCSQ
