yes exactly the same for both cylinder it songs good is my firt build i like it i think im gonna buy a old 107 cu inch and do it again but a real monster

 

If you can start and run it in the garage, you can save a lot of time on break in. Start it, set the throttle to 1500 +, let it run till operating temp. shut it off and let it cool off completely, repeat this 5 or 6 times and you are ready to go. That is how I use to set up engines for race bikes that you couldn't drive on the street. The heating and cooling takes the stresses out of the engine parts.

 

While the rings seal very quickly. The best seal you'll get is when the engine is "coming down in rpm via compression." This is when the ring lands are pushed against the ring grooves at their maximum ( in that direction.)

 

this is why a make yesterday run 2min shut down a bit then run 2-3 min shut down just to let the cylinder to be cold a bit just enough close to let my hand on it and i set my timming to 35 degree at 2500 rpm but i not run the rpm a 2500 for too long about 1 min just to set the timming

 

i just did the compression test for fun and i have 170 psi full throttle open but now i just finish the heat cycle procedure for the head gasket im waiting for the good temperature for ride it because here is 5 degree celsius now oufff im gonna check it after the break in procedure if the psi gonna up more maybe

 

This was good. I was taught by one of the best builders on here that 2 cycles to 150* jug temp is good to seat the rings.. I do 3.. Nice job
