Secret Honda GL1000 Ignition Tuning Tip Revealed

If you’ve read deep into this web site, you know by now that I’m “old school” on the subject of GL1000 ignitions. I happen to like old-fashioned breaker points. There are real performance advantages with electronic ignition conversions (like Dyna/S). I’ve run them on several GL1000s without complaint. But, I do field lots of questions from individuals attempting to solve various problems with aftermarket electronic ignitions systems on GL1000s. Often the problem is shoddy wiring of the switched 12V feed which powers these units. Fuses (when used!) sometimes blow without explanation. Sometimes, the “black box” circuitry inside these marvelous devices simply goes “poof.” Electronic ignitions never fail on your driveway. You’re usually at least 50 miles from home and the nearest motel!

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!

Fuel filters are not included in Randakk Master Carb Kits. But, it would be a crime to redo your carbs and not take prudent measures to ensure a pure fuel supply! We recommend the OEM Honda filter as a high quality replacement unit for owners concerned about originality..

For others – we offer the Randakk High Performance Fuel Filter with sizes to fit virtually any carbureted motorcycle. Details here.

Problems with Aftermarket Float Valves

I get lots of emails like this one: 

“I purchased four “Napco Carb rebuild Kits” in addition to some parts from you like plenum seals, etc. I probably should have purchased your Master Kit. Anyway, 2 of the Napco float valves would not seat properly resulting in a lot of frustrating problems. With your recommendation, I cleaned and put the original Honda float valves back into the carbs. Problem Solved. Thanks!”Lee Korb – Raleigh, NC
