So I'n breaking in my tomos, I just put a new piston and rings, old cylinder and head......I'm following the wikis instruction on how to break in a kit. I keep hearing a pinging noise in the engine (the piston) and I dont wont my engine to seize up like last time so am I doing anything wrong or right? is it natural?
Right now im doing 4 min heat cycles, I let it idle for 4 min and blip the throttle alil then I repeat 4 times and so one with the throttle even higher.(its in the wiki)
