hi Guys
another pesky little issue
having changed the chinky rad for a decent oem that fits properly and running it i still have the dial needle never lifting off the peg ( if i am riding )
if i let it idle for several minutes the needle will lift off the stop peg and the fan will start
so the gauge is working
i am guessing that the wax in the thermostat is gone and its staying open
the bike runs pretty fine as it is
2 questions:
a)worth fixing ?
b)the part is nls by honda
there is listed a pattern version by " caltec usa"
is this going to work?
i guess the later oem version which is still available is not a interchangeable part as its a lot bigger according to the pics
thanks for your ideas
paul

Paul, sounds like your thermostat is stuck open, or there is no thermostat. Just install new oem one. Remember to also order new o-ring gasket as it wont survive. Remember, the wax you mention is part of the cold start system, separate from the thermostat.

hi fizzy
i dont refer the a efi model with a " wax throttle up " device
i refer to the standard thermostat that will usually use a wax core as the pressure mechanism
further to that
i found that for the carbi versions in their infinate wisdom honda have nls the part which is rather short
there is a different nr for the efi version in a different housing that looks longer and so probably wont fit
however i discovered on the bay that there is a usa company
caltric listing a carbie version question is : is that a decent product ( for that price it has to come from china )
and
that: according to some ebay sellers a cbr1000f 'stat will fit( my old touring bike that i still have )
the official diagrams list part nrs of
the
xx carbie are 19300mat000/ 601
will fit cbr 1000 f 19300mg000
usually in honda speak the letters refer to the material used
so i am wondering if they are actually interchangeable
as the 1000f version curiously enough is still serviced.... even being 10 yrs older
go figure...
look forward to a concise reply

What year is your bike? If it is a 97-01 analogue dash model it is worth checking the PCB on the back of the clocks.
These PCBs are getting old and tracks break. If a track breaks (or gets corroded) you can get very strange readings (or none) on the temp gauge and fuel level.

Not saying this is the problem here but always worth a check.

hi Duck
thanks for your suggestion, which i had already checked when replacing the lights in the nosecone
as mentioned the needle does respond when the engine actually warms up
but unless the bike standing still for a long time it never does
this is the same for both my bb's
so my question about the caltric and other honda part nrs still is open
thanks
paul

My 97 doesn't see a lot of temp needle movement either. And fans cut in before needle hits halfway point when idling a long time. I think its a feature of the bike. There are no symptoms to suggest its a problem.

Yeah my 98 rarely gets above 1/2-2/3 even when hot in a WA summer as well but he's saying it never really gets off the stop and even in winter mine will at least go to 1/4 when fully warmed up :unsure: :unsure:
