Thoughts on engine break in via Dyno
I'm sure there must be mixed opinions on this, but...
I recently completed installation of new cylinders and pistons going from a 103 to a 107. These are matched by the builder to his ported heads and cams that I installed last year.
My challenge frankly is that with the heat where I live I really haven't been riding. So it took me some time to even get a 30 mile ride in to seat the piston rings.
I've been planning a usual break in procedure with oil changes, etc. based on riding that's not happening and then after about 500 miles get the bike re-tuned which I'm hoping won't be too difficult since it was done after the head and cam install.
So all this said, are there risks associated if I simply went to my Dyno tuner and have him run the bike and tune even though I only have 50 miles on the new pistons and cylinders?
Thanks as always!

I had my guy break my 106 kit in on the dyno. After that a full tune. On the dyno they can control everything. Its not going to sit there idling, like in traffic, unless he wants it to. Controlled environment is why I chose the break in procedure on the dyno

Thanks folks!
In regards to whether or not I need another tune after adding 4 cubes... I'd rather just do it, even if for my own edification.
And yes, my tuner is very good and conscientious

Mine is going to have about 50 miles on it and some dyno time before I pick it up . After I get some miles on it the final tune will be done.

My thoughts on this. Fuel isn't the only consideration. Doing nothing else besides going from 103 to 107. You added compression.
