Yamaha R6 Overheating



The clocks on my 200 R6 got water in them and didn't work.
A 200 R6? Solid wheels and big blades on the hubs?

I bought a 2nd hand set and plugged them in, and all seemed to be OK,
but the bike now overheats to 99 degrees.
99 doesn't sound all that terrible to me. I seem to recall that when I
had an R6 it wasn't properly warmed up until it showed around 85
degrees.
Mine sits at around 79 deg when rattling along at usual pace - fan comes on
(I think) just over the 100 deg and true overheating starts around 117 deg
(IIRC), where it's advisable to switch off and let it cool down.
Yeah that sounds about right to me too. I remember on the mugello trip
seeing 115 degrees when we were sat queuing in traffic to get in.
The VFR used to regularly get very hot slogging through London traffic -
especially in Summer. It often saw way over 100 degrees and the fan
would cut in at somewhere between 105 and 110 degrees.
What did it used to run at?

Is the tempaerature control in the clocks, or is this another issue?
It won't be boiling until you get to about 110. Does the fan cut in
and out, is your coolant level right, have you plugged all the wires
in, in the right places and the right way round? These, and other
questions all need answering.

Please help, cos I can't get out on it like this?
Is it the gauge that's wrong or the bike "actually" overheats?
My guess would be that it's the clocks that are playing up.

Do the clocks show a low temp when it's cold, and warming up, or does
it just show 99 when you turn it on?

Cheers,
Kenny
