I want a new  chainset... but now I seem to have a problem. The framenumber starts with 3CX build 1988. But I have ABS and is imported in Europe in 1992.
Which chainset should I buy or isn't there any difference between? Thxs

Modifications / Timing Plate Mod
Last post by miatamarty - November 21, 2025, 04:46:15 PM
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?

Quote from: FJmonkey on November 20, 2025, 10:59:43 AM.....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.
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.
