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.
Got the head on.
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.
All done for now. Still fine tuning.
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.

The Low Season by Andrew Watson
Here’s the latest motorcycle film from our good friend, vintage motorcycle rider, and Philly native, Andrew Watson. You might remember his Waiting Out Winter video with Cast & Salvage from last year. We might not all get to ride a Royal Enfield in through Northern Indian but it definitely gets me excited for my motorcycle […]
