I had been looking for a while now for Piston Kits for my 3 bikes.
The Z1 is a no-brainer. Weisco makes anything you need for a Z1 / KZ900 / KZ1000.
I was having a real problem finding kits for the cb450 and cb650.
I eventually found kits that drop right in after a little minor boring. No sleeving required. Nice little bumps in compression.
I wanted to share the links to the companies.
Check them out.
They have a bunch of good stuff for the Honda fours and twins.
Note that Charlie Place pistons are made by Weisco to special specs. I think Dyno Man’s are too, but I can’t confirm.
Charlie-Place has electronic ignitions and better regulator rectifiers too.
