Ottoco MLS Head Gaskets
Gasket specialist Ottoco has introduced high-performance head gaskets for the 1973-78 SOHC Honda CB750 and the 1973-84 Yamaha XS650. The multilayer steel head gaskets are designed to give maximum sealing performance and feature embossed viton-coated steel outer layers to provide an even clamping load across the sealing surfaces. The middle layer is made of un-coated stainless steel. Ottoco says no sealants are required, and they don’t need to be re-torqued. XS650, $49.50; CB750, $57.54.

Maxi-Dwell II Ignition
Campbell X-Pipe says its Maxi-Dwell II ignition for points-equipped Japanese four-cylinder bikes (including all 1969-1978 SOHC Honda fours) improves timing accuracy for improved running that rivals electronic ignition systems. Timing is simplified and made faster thanks to a built in switch enabling instant switching between cylinder pairs. The General Motors automotive ignition points are mounted on an aluminum plate and are said to last 20,000 miles. Campbell says point bounce or float is eliminated using these points. $99.95.

The DOT approved K3 (shown in Basic Red) features removable and washable interior padding, front and rear air extractors, and AGV’s XQRS quick-release shield that pops off in seconds. $169.95-$219.95.
