Greetings All.... New Owner Of An '89 Needs Advice.

Well, I respect your opinion greatly Noel. But personal experience matters as much to me as theories, if not more. While I am aware that water enters the lines via the atmosphere, my impressions has been that DOT4 fluid are so hydrophilic that they draw the water in, attract it. Since DOT5 doesn't have this relationship with water, I can understand water not being drawn into the system.

But, if you did care to argue it, I'm not dogmatic. I put those points to you as much to show the other side as to hear your counter, if any.

But as you wish! As I said, your opinion is always welcome.

Using some one else's personal experience as a guide is only of value if they are qualified to understand and interpret their observations. The absence of an adverse reaction does not necessarily make something the right choice. My view is not formed from theories but research by people who are qualified and whose job it is to make these findings and in many cases, produce the original technical notes, not anecdotal evidence.

To look at it differently, why would you bother. They both SHOULD be changed regularly, It's a PIA to introduce it and 3 to 4 times the cost of DOT4 and you are addressing a problem that's not really there.

Automotive manufacturers have enormous R&D facilities and the trend is increasingly towards "sealed for life" cars (and bikes) There is virtually nothing to service on them now and with longer intervals between services.

It is not a bad source of information to keep an eye new vehicle trends and their choices are not always about cost. You could reasonably expect to buy a new vehicle today, put hundreds of thousands of miles on it and not put a spanner to it.

In the 70's this sort of reliability was something you would only find in manned space flights.

If they don't use something, why? you can bet they've tested it.

I find it at least a good reference point to start from.

I just use DOT 4... Because if the known issue with the clutch salve, my plan is to bleed some fluid out and replenish as needed every spring and again at the end of the season while changing oil. A few years ago I rebuilt mine, and knew there were some problems in the bore. This winter I bought a new one from Randy.

My parts from RPM arrived today. I was surprised at how quickly they arrived! Thank you for the fast shipping. Now I just need to wait for my SS brake line & I can get to work. I can't wait to ride this bike for the first time.

I'm still interested in this fluid issue.

Thanks

Yes he ships real fast ! I won't throw any log on the digital brake fluid fire.

You know, you prompted me to do some more reading, and I'm back to being on the fence and leaning on the side of conventional knowledge.

See, opinions do change.
