(THANKS ENZO) sometimes the inner cable length on the stock cable may be a little bit too long for the aftermarket carbs and not allowing for a complete throttle slide lifting, so you may want to get a solder on cable end so you can shorten it if needed... our number is (END)sold seperatly Dear dratv, the carb fit perfectly on my CL90. i did re-use the main jet as it was identical (except orifice size) but the idle jets were different lenghts so went with the one it came with. thanks - gumpwood59 300012
