Everything Affects Everything!

I was inspired to create this Tech Tip after reading an old post by Jim Myers on the Classic Wing Club mail list. The general context of the thread surrounded the issue of setting idle mixture screws.

My view – a proper carb rebuild on a vintage ‘Wing, properly MAINTAINED should be a once-and-done proposition that gives years of reliable and trouble-free service. That’s always been my personal experience!

Otherwise, if you use inferior parts or take shortcuts – you can take advice from Alec Baldwin

Pod Air Filters or Aftermarket Pipes on Vintage Hondas?

I get a steady steady stream of questions about re-jetting for aftermarket pipes on the range of vintage Honda motorcycles we support.

Shade Tree Diagnostic Tests!

I was very fortunate to grow up in a neighborhood and farm family full of excellent shade-tree mechanics. Mostly they were short on cash and long on resourcefulness.

I learned quite a lot by pestering these very talented home-gown mechanics.

More on Fuel And Fuel Additives – Fear the Corn?

Warning: Controversial Material!

Corn Ethanol Fuel

I grew up in a farm family in the South, so I’m very fond of corn. Of course I like grits, but my favorite form of corn is high quality bourbon! I have personally benefited from crop subsidies and understand the benefit of the emerging ethanol (made from corn) fuel market to corn farmers. I am sympathetic to their issues.

Kick Starting a ’75-’77 Honda GL1000

Starters are very reliable on GL1000s, but it’s nice to have a back-up. The back-up kick start lever is found only on ’75-’77 models. Honda deemed this extravagant redundancy was unnecessary and dropped the feature on later models.  I’ve actually needed the kick starter on several occasions to make it home when some aspect of the very reliable electric starting system failed. I also use my kick starter for another reason: it’s a good test of your bike’s overall state of tune. If it will start with the kick start lever, then you have a well tuned bike! There are many maintenance operations (like setting timing) where the kick starter provides some nice convenience.

Motorcycle Fuel Mileage Issues

Warning: Controversial Material!

I get lots of inquiries about fuel mileage these days. It’s no surprise given highly volatile fuel prices! Here’s what I know about the subject.

Vintage Motorcycle Carbs – Lean vs. Rich?

Carb Adjustment, Lean or Rich

Experienced wrenches sometimes forget that we operate with a set of understandings that becomes so ingrained as to become second nature. I don’t normally rely on gizmos like the K&N Air Fuel Monitor shown on my supercharged GL1000 (above). But since things happen so quickly on that bike, it’s a useful and entertaining tuning aid.

Tips on Buying a Used Honda GL1000

Introduced in 1975, the Honda GL1000 was a stunning technical achievement. The original, unfaired GoldWing was the world’s biggest, heaviest and second fastest bike available at the time (only the mighty Kawasaki Z1 was swifter). Novel features included a liquid-cooled flat four engine, belt-driven overhead cams, shaft drive, triple disk brakes, under-seat fuel tank, counter-rotating alternator, two oil pumps, “floating” piston pins, faux top shelter “tank” and detachable back-up kick-start arm to mention a few. Honda used the GL1000 to showcase its considerable engineering prowess and put other motorcycle marques on notice that it was a force to be reckoned with. For the first time ever, there was heavy collaboration between Honda’s motorcycle and automotive engineering teams on the ’75 Wing.

Brake Bleeding Tips

Bleeding the brakes on a GL1000 is straightforward and well-covered in any manual. However, this can be a most aggravating task. Below are some tips to reduce your frustration.
