Randy - RPM

I'm waiting for a new set of carbs from RPM. Randy asked if my timing plate was slotted. Don't know. He did mention that he thought there was a thread here. For the life of me I can't find it. Help?

Au contraire my simian amigo... DOT 5 has substantially higher wet and dry boiling points than DOT 3/4.

However, DOT 5.1 vs DOT 5 are very close

DOT 5 wet: 356°F
DOT 5.1 wet: 356°F

DOT 5 dry: 500°F
DOT 5.1 dry: 518°F

That said, I have DOT 5 in my '84 and DOT 5.1 in my '89. There is a subtle difference between the two.
Both front brake systems with identical components, Spiegler lines, R-1 calipers and 2001 FZ1 14mm masters.
The lever feel with the DOT 5 is softer (not spongy) than the system with DOT 5.1.

If you are using DOT3, 4 or 5.1, keep it covered/sealed from the air when possible. They will absorb moisture. This is why we need to change/flush the fluid when it gets dark. This is also why some of us have converted to DOT5 (ok for street but can't take the higher heat of hard frequent braking.

I leave it closed. There is air space under the covers, and when the bubbles make it there you are set.
