400/4 F1 Cafe Racer Project - New Exhaust System - VIDEO WITH SOUND ADDED

[robnobrakes]

Mizuno Motor (copycat Yoshi) Short Exhaust System now fitted to my '77 CB400/4, replacing a 1970s Yoshimura 'Long' system.






Removed Yoshi Long system

Very nice house you have. Must take some cleaning The bike is nice. Is that brake disc safe?

[SteveD CB500K0]

Big house.

Big garden.

But does it have a garage?

That front disc is for trimming along the (left hand) edges of the lawns.

First link to open pipe (baffle removed, nice but too loud).  Second link to drilled end cap and baffle refitted.  The exhaust was too quiet with the baffle as supplied.

I can see that getting clobbered by speed humps, nice pipe, shame about the design work that clearly hasn't gone into it.

Possibly, but this was designed by Yoshimura who are a quality outfit.  I can't remember if speed humps were about in the 1970's when the exhaust was first manufactured.  Next speed hump will be interesting.

No issues with the front brake, so yes, it is safe.
