Daniel says: A reader asked about the noise from the cylinder head on his rebuilt Honda CB72. I think that the problem is with the rocker spindles as they are different sizes from one side to the other. You have to size them which is very difficult because they look almost identical, it is a quirk of Honda engineering and the 72 has a number. The very small amount of difference in size is enough to give the symptoms he speaks of as any long term 72 owner will tell you.

About the Author

Bertie Simmonds

As a child Bertie (well, Robert back then… blame his sister for the nickname) was exposed to motorcycles thanks to his uncles. They would show up at his house with a lovely lady as pillion throughout the 1970s and 1980s. After a naughty time on field bikes (it’s what we did back then) Bertie passed his test in the early 1990s and became a reporter for MCN in 1995, moving to the sports desk and covering World Superbikes in 1996. With a change to Bike Magazine in 1997, he stayed until 2000 as news, features and road test editor. Moving into PR with Cosworth, Bert was bored with cars and returned to bikes in 2001 with Two Wheels Only, becoming editor in 2002 and leaving to be freelance at the end of 2004. With almost a decade freelancing, Bertie joined Mortons in 2013 and became editor of Classic Motorcycle Mechanics, a post he’s desperately clung to, to this day. And no, he’s never had a pretty girl on the back of his bike.
