You may want to take a look at this,  I used it to "break in" my engine a couple of years ago, and it seems to have worked a treat.

Have talked to many Harley independants over the last couple of years about this very subject and most agree with it, Too do a good job with "Piston Ring to Cylnderwall" sealing, dont use "synthetic" oils and ride it like you stole it! 

I changed my oil after 50 miles, then again after another 200, and didnt start using "rock oil TRM" untill had 1,000 on the clock.

I have "no oil " usage at all, with exception of the very small amount from the breather system (I use a catch can to keep the cylinders and pistons crowns  clean).

That was interesting.

You will find Axtell, S&S and Hastings breakin procedures on the net. None are even close to this method. Axtell provides solid reasons why not to wale on the new motor.

I've read that article before.  No way I'd follow that interweb link method.

I tend to agree. Although it was an interesting read, I don't think "rather I'm sure "I won't be dumping the amount of oils into it that's suggested for breaking in.      I don't even change myselfs motor juice that often 

It's always been, for me anyway that a motor is run at 50mph with the odd short burst  up to around 70mph then slow back to 50mph for next 500mil of breaking in time. This is the first HD motor but have done a few other motors with what I just mentioned break in and have never changed oil like it said too.

Did a check on the rings and found the middle rings are almost polished  the complete depth of the face of the ring the gap ends were completely polished.
I've decided and ordered a set of Total Seal rings should be here the middle of next week. By the way the 07 stock rings are 1.2mm comp and 2.5mm oil these are discontinued by HD you have to go to 113 upgrade piston and ring I was told so went with Total Seal.

Someone gave you a bit of wrong information.
21951-11 std and 21953-11 .010 are the rings. EXPENSIVE!

Now why does that not surprise me.

It was my local HD dealership informed me they're discontinued. I looked up the the part number the cost was high a lot higher than Total Seals cost including shipping from your side of the pond.

I'll hit the dealer up with that part number and see what they have to say.

Thanks for the input

Rings arrived today from Phoenix, Arizona. Not bad going as it took only 9 days from date of ordering.

The rings that came despite  what the year and part numbers for my 07 ultra say the rings were the wrong ones 
Every where I've been looking I was coming up with the same size of ring 1.2mm top rings and 2.5mm oil. To big for the top  and to small for the oil.

Well I had to buy myself a measuring tool and do it the old fashion way.  I called Total Seal and gave them the piston grove measurements  over the phone.

For the 07 I've got, the rings are 0.43" top rings and 3.mm oil

NO where even from the dealer do they come up with these rings.

The reorder came today the rings fit and assembly has begun.

Been keeping busy waiting for the right rings to come.
I put on a new fork slider (chrome was peeling). 
Changed fork oil
Changed brake and clutch fluids
Chased down a short in the SPKR switch system and repaired
Replaced the rear brake pads

Got the cross hatching on the front pot done and cylinder on today will start the rear tomorrow.

Fingers crossed I have no more setbacks.

Something I'd look in to  about 50k down the road.

So after all that time and a billion bits scattered around the garage you didn't cock up anything?   Well done!   


Always feels good the first time you hear one fire up after it's been apart.
