July 12, 201610 yr Changed my RL250 which was using 40:1 mix to an RL325 which has had rebore, new piston and rings. Should I use same mix running engine in?
July 13, 201610 yr Have you changed the pilot jet in the carb ? 250 is 27.5 and the 325 is 20 main jet is the same. I'd say yes just give it a little time to bed in, so don't rev it out
July 13, 201610 yr Author Thanks for that and yes changed jet. Have you changed the pilot jet in the carb ? 250 is 27.5 and the 325 is 20 main jet is the same. I'd say yes just give it a little time to bed in, so don't rev it out
July 17, 201610 yr My 250 with a 2mm overbore is on 125 main and 37.5 pilot on a VM26 and its perfect from walking pace. 27.5 was very baaaaaa on the VM26 A quote from Jim at BOC for the VM26 .
