New Moto Guzzi Door Mats Available Now
When I had my H2's head apart 35 years ago, I put a grease fitting in the head tube. I put a couple squirts in there every couple years, and the original bearings are still smooth and not notchy. I don't know why all motorcycles don't come that way.
I was an auto mechanic briefly in the early eighties - I recall when new autos started coming out with either no option for a zerk or a plug, and you had to install your own.
My old triumph has zerks on the swing arm bearings. :BEER:
At my next regrease at 50,000 miles I'll change the bearings out to rollers.
