Default Break-in Before Breathing Free?

Hello -

I am going to pick-up my '07 Street Glide in the next couple of weeks (why do we work so flippin hard?).

I am 100% certain that I will add V&H slipons, SERT (if they are back in stock by then), and K&N (or some other preferred breathing apparatus).

Do you think it is BETTER for the bike to go through break-in before doing the mods?

I am thinking I'll ride her stock through break-in then get into that stuff. In the past I have jumped right into the mods to get them running "free-er"...I like the idea of being able to really note the diff, as subtle as it may be, between stock and exhaust/air/fuel mods...but mainly thinking about what's best for the bike.

Any issues doing it right away (aside from the sucking sound on the 'ol bank account)?

Thanks!

SGN

No issues. I would just follow the HD break in procedure. It's quick and
easy.

My dealer recommended I wait at least 500 miles before a dyno. Shop around for parts prices. I got my SERT from Mark at M&M Cycles for just under $370 and my pipes V&H Tru Duals with Oval Slip Ons complete for just under $800 shipped.

A stage 1 done before delivery is quite common and if anything it would help your bike during break-in. Think about it, bikes run like crap stock so that's why we DO a stage 1. Why not have the bike run good from the beginning of it's life.... just follow the same guidelines(rpm's and speed) during the break-in period...

If you want it to run strong and not burn oil on down the road, run it like you stole it from the get go, vary speeds, take up fast and let off to seal rings, just dont overheat it. I wouldnt let some rookie tech dyno a new motor, I had rather be in controll of its break in. First 50 miles is the crutail period, after that whatever you do doesn't matter much.

+1 That old way of breaking in engines is....well OLD. That way was good back in the days of very loose tollerances in the engine building process. So the piston rings had to find a "Seat" so that oil wouldn't blow by into the combustion chamber. Now, engines are built to very exact and close tollerances and the rings are seated and theengine is well on it's way to being broke in before they leave the plants(Assuming HD runs every bike on a dyno after assembly, which I am pretty sure they do).
Here's a very good read on the break in;

You want your break-in period to set the stage for the next 100,000 miles. In my opinion, anything that helps the bike to run better, run more efficiently, more effortlessly, and run cooler is better for the engine during that crucial break-in period. My new bike gets the intake, exhaust, and electronic modifications right away.It also gets immediatelyswitched tosynthetic oils.
