48mm Big Bore Help

[16lanlev]

I have a 1986 Nq-50 and my piston and cylinder is all scratched up so i need to replace it, My plan is to switch from the 41mm to a 48mm but what else will i have to change to convert it? Thanks

You will need to modify the air box or switch to a pod style airflter, you will need a larger jet in the carb which is sometimes included in the kit. You will need to pemix your fuel in the tank and run the oil injection.
