Frequently Asked Questions
How many 07-0185 standard-size piston kits are required for a Honda CB350, CL350 or SL350 twin?
One piston kit with piston rings and pin is included. The Honda CB350, CL350 or SL350 twin requires two kits to replace every piston.
What must be measured before ordering standard-size pistons?
Measure every cylinder for bore diameter, taper and out-of-round and compare the existing piston markings. A worn or previously overbored cylinder may need machining and oversize pistons rather than standard size.
What clearances must be checked during assembly?
Check piston-to-wall clearance, ring end gap, ring side clearance and pin fit to the specifications for the exact engine. Install ring markings and gaps in the specified orientation.
