Re: Proper Break-in and Making your engine last.
I think 4-500 miles is a lot for break-in also. I went through 2 tanks of gas at 16:1. At that mix, it didn't have much power do do much harm. I went through a lot of full throttle on & offs (mostly trying to start the #%?* thing)
I've been only riding a few blocks at a time.This week went to 20:1. Starts much easier and runs better. Went on a 3 mile trip to the store today. With the shifter kit installed I didn't use much throttle except dodging cars.
Mine 4 cycles at higher rpms, so it's like a governor anyway.
I think after this tank it'll be ready for some carb tuning and be broke in enough .
