I start it check for leaks let it warm up ride it for 15min normal not beating on it then let it cool, retourqe head and cylinders. then repeat once more then just ride it.

I just freshened up my top end also... it was right before I joined BANSHEEHQ.

so I ran my first quarter tank 20 to 1. I let it warm up while i check for leaks.

Took it for spin. Then I let it cool down. drained the fuel retorque head. Ran a

normal tank of gas 32 to 1. Finally then change the oil or tyranny fluid.

There are a million ways to breakin. Everyone's way is the best. Years ago I was told:

 

Start the motor and let it warm up. Go go a cruise varying the throttle from 0-1/4. Shut it down after it is at operating temp. Let the motor cool down completely.

 

Start the motor let it warm up vary throttle from 0-1/2 but not too aggressively. Let the bike come to full operating temp. Shut down and allow to fully cool again

 

Start the motor and let it warm up. Again vary the throttle from 0-wot until operating temp. Ride until operating temp and shut Dow again allow to cool completely. Retorque head.

 

I have not had problems and I get a lot of life from my motor. If you changed nothing check jetting always. I do not run any different mixture than I run when normally riding a motor that is broken in.

 

These heat cycles take maybe 15 minutes you are just trying to get the piston skirts to hardent and allow the rings to match the bore.

 

Don't ride it like you stole it and always allow the motor to come to temp and you will have a long lasting motor

Thanks guys. This is my first attempt to a rebuild and I think everything is going great but I am still a little nervous when I go to start the shee for the first time.

[ticktock]

It's not bad to rebuild. Keep things clean, install clean parts start clean you will be fine

 

When I do a rebuild I normally pull the motor. I plug the intakes, exhaust and I take the motor to the car wash and pressure wash it to remove all the crap. Then I take it to the hobby shop (I am in the military and most bases have a spot to work on cars for a nominal fee, they furnish a place to work and tools) and I use the solvent tank and clean it up more removing everything.

 

Then I disassemble the motor and I like to bag all my nuts, bolts parts and label them. Clean everything again, make repairs and assemble. Cleanliness is next to godliness!! Haha

 

There is a lot of knowledge here from professionals to backyard builders and everyone likes to talk and help!

Well when I had an guy that a few people on here know, his name is Kevin Herr. Anyway, he told me to put it together, start it, them said look for leaks listen for crazy noises. If it all sounds and looks good, ride out like you stole it. He has built a few engines, I'll take his word for it.

ride it like you stole it..

 

warm up break in results in more frequent rebuilds.
