Stomp77 Posted October 21, 2003 Report Posted October 21, 2003 I just rebuilt my shee, with vito's power piston's and a tdr Hi-Po crank. I have started the break in with amsoil 100:1 premix at about 44:1. I started the enguine and let it idle until hot giving it small blips on the throttle. I let it cool for 4 hours and rode it around the yard nice and easy for five minutes, I only got into the power band in 2nd 3 times. Its cooling right now, and i am about to go out again. only I read a post just now where someone said that you have to break a new engine in using regular old dino oil becasue there is virtually no metal to metal contact with synthetics. Can i safely switch to kawachem for the rest of the breakin at say 32:1 and then go back to amsoil? or should i stick with whats already been run thru? its my first rebuild can somone help out on this one? thanks..............

PassionRE Posted October 22, 2003 Report Posted October 22, 2003 Dino oil for the first 2 gallons of use on overhauls and re-rings...Jim Quote
rzcolobanshee Posted October 22, 2003 Report Posted October 22, 2003 Your rings will not seat with synthetics, put dino through it, you need to start the breakin process all over, and if you are running a richer mix you need to richen up your jets because you have a leaner air:fuel ratio Quote
