® Real issues
Items either characterized wrongly or completely ignored on many motorcycle user forums


The images above depict the number one issue facing vintage Japanese motorcycle owners today: receded valves. Yet, do you read about this on forums? No. Not a whisper. Instead, they insist that compression tests are unreliable, inaccurate, inconclusive, and excuse poor compression as non-existent -- a non-issue, thus ignoring why their engines have low compression in the first place and run less well than they should. This issue should be at the very top of their threads, it should be thoroughly discussed and warned against, and remedies enumerated and qualified. Most Internet powersports user forums are insidiously vacuous, self-focused, self-promoting, iconoclastic, unresponsive to the industry and exceedingly unhelpful to those seeking help. They are places no rational, intelligent individual should have anything to do with. Here's a short list of topics misrepresented or ignored on forums. See how many you are curious about.

In short, practically any given subject being discussed on the average user forum is way off base, steeped in lore and myth and unqualified opinion. Why doesn't the truth about the things in the list above characterize forums? Why did it take online forums more than twenty years to agree with career techs on the subject of carb rebuild kits, and far longer about OEM ignition points? And most still argue. Why are forums, instead of disseminating real things, inexplicably enamored with Chinese replacement parts; "velocity stacks"; repair practices originating in, at best, 1940s car manuals, and at worst the imaginations of unqualified hacks; the weight of mass opinion; "M boxes" and a myriad of other empty, meaningless things? Why indeed! I don't really know, but the fact that they are should indicate something, should be a warning.

Do you know that forum members have seen this list? I link to this article (via this censure of forum deception) in most of my forum account signatures. To date only one person has started dialogue with me about these issues.

Motorcycle user forums are on a different planet than is the powersports industry. Forums are not the clearinghouses of powersports knowledge. They are not even a part of the industry. They are rebel outposts and absolutely clueless, pecularly isolated communities contemptuous of facts. And they want to stay that way. They have made up their own truth, a different, false set of facts, and they will not listen to reason.

User forums have a responsibility to their members, one they are not only ignoring but perverting. Because people depend on them. I welcome civilized dialogue on these issues.
