Welcome

Welcome to the Dunstall Honda Blog.  I will be updating with my 1971 CB750 Dunstall build as well as everything Dunstall Honda.

The Build, Part 6 (Spring 2016)

The Dunstall Honda got some suspension and brake upgrades this Spring.  A new Dresda replica box-section swingarm was added along with some NOS Magura Power Levers, drilled and skimmed disks front and rear, a new MCP rear master cylinder and some Progressive Fork Springs.

The Build, Part 5 (Summer 2015)

The Dunstall Honda got a Hurst Airheart rear drum to disk brake conversion this summer.  The kit was available for a short time in the mid 1970s.  I based my conversion off the original kit and used the Hurst Airheart caliper and master cylinder.

The Ride

Went for a nice Fall ride on the Dunstall.  Possibly the last of 2012.  Lots of sun with brisk temperatures.  In other words the perfect weather for a fast ride up NY Route 5.  While not the curviest of roads, Route 5 offers fast 55 mph 4 lane blacktop with a nice mix of woods, stores, plazas, and neighborhoods all along the shores of Lake Erie.  I stopped for a few pics at Hamburg beach.

 

The Build, part 4 (June 2012)

Minor updates for 2012: Replaced the real Dunstall Decibel silencers with British made replicas from Brituro.  The new silencers aren’t exact replicas but they sound and look great.
