Jump Starting a Vintage Motorcycle?

Warning from Randakk: Controversial Material! 

I am not a big fan of “jump starting” a motorcycle. In my view, this procedure should generally be avoided. I believe it’s better to anticipate, prevent, diagnose and fix problems before they degenerate into roadside “no starts.” But – sometimes bad things happen no matter how well prepared you are. Jump starting can be done in an emergency situation with relative safety if you follow these tips by Howard Halasz. I truly hope you will never need this information!

Recommended Honda GL1000 Timing Belt Change Interval

My recommendation for Honda GL1000 timing belts is simple: It you can’t verify their age – change them! Thereafter, my recommendation is to change them every 5 years or 25,000 miles…whichever comes sooner. Obviously, they should be inspected from time to time for any evidence of damage or deterioration which would warrant immediate replacement.

Here’s a partial list of problems encountered by amateurs when rebuilding GL1000 carbs. Often, I’m called upon to resolve botched rebuilds by incompetent mechanics, current or previous owners, brothers-in-laws and neighbors. Avoid these mistakes if you tackle a rebuild yourself.
