No compression

Hi,
i have this 2011 883L, with brand new pistons, rings, jars, pushrods and valves. I get zero compression at the rear cylinder, but good and proper compression at the front. Please help me out 😕

Squirt a generous amount of oil in the cylinder, if compression comes up at all it's probably the rings and/or bore. If no rise in compression it's probably a valve.

Got compression !! 👍🏻

I had wrong timing done. Minor mistake. Now there is compression. But the rear cylinder is spitting oil !

No ****, me too. Did you install the camshafts correctly? How about the pushrods?

thanks for the reply 🙂
I previously did the timing wrong. I think I missed a tooth or 2. That's why there was no compression.
Now fixed it. The problem now is, the rear cylinder spits oil. It's all white smoke, only from the rear cylinder. Since the piston rings and cylinder are brand new, I doubt the valve seals now. No idea. Will update here. Cheers!
