Z1 Engine Teardown – Part 2

Got my cylinders back from Powerseal. Bored out to 1015cc.

Got the cylinder head back from Mar Auto. Those guys are the best.
– I had bent valves and loose guides
– had 3 angle valve job done
– they installed all new valves, springs, guides, seals and set my cam-valve lash
– done super quick with a great price and good communication

Wiseco 1015cc piston kit. 10.25 compression.

My workshop space in the garage.

Sliding the cylinders over without a ring compression tool is the fucking worst. It took adam and I a long ass time and a lot of cursing. But we eventually got it.

Boom.

z1-finish-09

Got the head on.

z1-finish-07

Web Cam #118 grind.
Basically the mellowest cam upgrade I could find. I originally wanted to go with more lift… but this is my trip bike so I went conservative.

z1-finish-08

All done for now. Still fine tuning.

z1-finish-10

There are a couple little air leaks that I’m addressing, and and couple other tuning things.

Overall the bike fucking rips harder than before. Especially over 5k rpm.
I dig it.
