Not just the best Japanese motorcycle  – the best motorcycle available anywhere in the world. Period!

Intake Runner Leak Testing Method for Honda GL1000, GL1100 and GL1200

This Tech Tip is provided courtesy of Fred Reckling of Las Vegas, NV.

In my Honda GL1000 Carb Rebuild video, I show the method I use for testing intake runners for hidden leaks. I use rubber stoppers and a vacuum pump for this testing. My method works very well, but sometimes folks have a challenge finding the right size rubber stoppers and the hose barb needed to duplicate my rig.

Fred Reckling devised a slightly simpler method that works very well. This method works for GL1000, GL1100 and GL1200 intakes.

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
