Guest bigkahuda Posted July 30, 2013 Share Posted July 30, 2013 Hello, the temp gauge on my '93 VFR was not registering a change after running for awhile so I tested the gauge and it passed so I replaced the sensor with a new Honda unit. Now the gauge moves, but it takes a very long time (10-15 minutes of riding) just to move about 1/4". Where on the gauge should the needle be after a normal warm-up is achieved? I've even had it hot enough to activate the radiator fan and the gauge is somewhere around 25%. Is this normal? Thanks for the help! Link to comment Share on other sites More sharing options...
Member Contributer YoshiHNS Posted July 30, 2013 Member Contributer Share Posted July 30, 2013 Someone else who's actually riding can confirm, but I think mine was below 1/2 at leisure riding on a 70-80F day. If you let the bike sit and idle after a ride, does it go up? Link to comment Share on other sites More sharing options...
afpierce489 Posted July 31, 2013 Share Posted July 31, 2013 So, I had the same issue with my 93. In the end, I replaced the thermostat and sensor unit. Now my gauge sits at around 1/2 on normal days. On hot days it can get up to about 2/3 to 3/4, but as soon as the fan kicks on, it goes back to about 1/2. Link to comment Share on other sites More sharing options...
Member Contributer YoshiHNS Posted July 31, 2013 Member Contributer Share Posted July 31, 2013 Yeah. I was going to suggest that if his bike won't get to 3/4 or past that it might be a thermostat issue. Link to comment Share on other sites More sharing options...
Member Contributer gll429 Posted July 31, 2013 Member Contributer Share Posted July 31, 2013 i ditched my gauge long ago.. i just took the thermostat out and cut off the spring plunger bit and put it back in. yes it takes an extra 2 min to get up to normal. but i now never have to worry about over heating in start stop traffic. unless the fan goes on me.

Member Contributer mk2davis Posted July 31, 2013 Member Contributer Share Posted July 31, 2013 My 91 hovers around 1/4 most of the time. Only in sitting traffic does it go higher. Fan comes on at about 3/4. Link to comment Share on other sites More sharing options...
Guest Posted July 31, 2013 Share Posted July 31, 2013 sounds like I should try a new thermostat. thanks for all the great input! Link to comment Share on other sites More sharing options...
Member Contributer YoshiHNS Posted July 31, 2013 Member Contributer Share Posted July 31, 2013 Not just yet. If your bike sits at 1/4 during riding that may be fine. What you need to do is try to get your bike to overheat. If you can't get those temps up to 3/4 or past, then you have an issue. Should have asked earlier, but, did you replace the sensor with the OEM Honda part or an aftermarket one? Link to comment Share on other sites More sharing options...
