Then take it easy until you get to 1000 miles.


I recently completed the build noted in my signature. I did the 50 miles (and oil change) and made it til about 400 miles before I started riding it hard (meaning bouncing off of red line) this week. My buddys riding behind me didn't see any red hot pieces of piston ring or smoke coming out of my exhaust, so I think the rings are seated OK. Gonna change the oil and I'm getting it dyno tuned next week. I believe if it is put together right, what I did is more than adequate for a proper break in.


BTW, a friend got a 106 S&S set up done by T-man and rode it like he stole it right out of the shop and his runs great and doesn't smoke at 20K.


Good luck!
Doesn't sound easy to not keep constant rpm.

I'm just saying what they recommend. I don't think they mean that too literally. Just don't ride for 2 hours with the cruise on.

If you're gonna dyno it the tuner can properly seat your rings with several heat cycles.

I bought my stuff from Dragos Bike Works and on the packing slip it said to use Mobil 1. That's what I have always used anyway. And no, I am not trying to start another oil thread. Just passing on what a reputable builder recommends.

Yeah, I guess every builder has his favorite. My build sheet recommends Shell Rotella. I have always used SAE60 in my bike. Should I change to synthetic at this point, or just continue with What I have always used?

I'm a little confused about the pushrod and valve rocker installation. The manual states to find the base-circle, using the methods explained earlier, however, those steps require the pushrods to be installed. That way you can have the valves open and close and feel the compression stroke.

So, how can you be sure you are on true-TDC without the valves installed?

Since I used the quickie pushrods before, do I need to screw-in the pushrods and go through the whole re-adjustment procedure?

Thanks!

I would readjust the pushrods. When you're done installing the cams, the alignment lines on the camplate and cam gears should be aligned indicating that the front cylinder is at TDC.

Another way is to rotate the engine by hand watching the lifters. As each cylinder reaches TDC on compression stroke, the lifters will be on the lowest part of the cam and stop moving briefly. You can see it or stick your fingers in the lifter holes and feel it.

Use whatever oil your builder recommends for break-in. then go with what you usually use.
