A LOT of blowby smoke after engine rebuild

It's not more slippery, but it keeps the parts from wearing better, not what you want.

For lack of a better way to state it, I choose the word "slippery", which in effect means reduces wear. But again, I don't think synthetic oil reduces wear under any normal usage over regular dino oil. Where the synthetic oil stands out is under extreem heat and in that it doesn't break down very fast - thus it allows an extended change interval.

Don, something you can do to speed up the ring seal process is to run the bike up to about 6000 in 5th gear & then close the throttle & let it come back down to about 2500 & run it back to 6000 & close the throttle again. Keep repeating this & it will help the rings to seat. What it does is when you close the throttle it creats a vacuum in the cylinder that sucks the rings to the cylinder wall. I've been breaking engines in this way for a LONG time & it works! I even do it to dragrace engines a few passes to speed up ring seal. The only thing I can think of if it still persists in smoking is that you may have installed either the top or second rings upside down. That would DEFINITELY cause a lack of ring seal. If it won't seal up & you have to take it apart I would look there first. Good luck, Ray.

Somewhere I read that I wasn't supposed to lug the engine but I'll try it. Thanks. I've done something similar but it wasn't all the way down to 2500.

And guys, I never used Synthetic in this engine. Valvoline 10W-40 for the first 200 miles and now Honda MC oil 10W-40.

This doesn't mean to slam it open & lug it. Slowly open the throttle to bring the speed back up so it doesn't lug. If your 1100 won't pull back up slowly from 2500 you have a LAME 1100. Ray.

It most definitely does pull.

Ran a compression test yesterday after a short ride. Good news. 150psi across all four cyls !! :-D Still smokes but I think it might just be all that excess oil I was dumping in those cyls over the last four years.
