It isn't worth whining about.
It is easy to say that. but if YOU walked out and saw coolant leaking from underneath your injection system and you knew you were going to have to do the same repair, I do not think you would be overjoyed.
Great write up Action. Glad it is a sticky
Just re-read. Lifting the TB tomorrow. Thanks for all the tips fellas.
May have to clean the grease of the wife's hairdryer before I put it back in the drawer LOL
If you put a thin coat of RTV on the inside surface of the couplers they will slide together almost effortlessly and removing them the next time will be a snap. this works geat for coolant hoses as well.
Try it you'll like it.
I did my 2002 t-stat last night and it went very well thanks to this thread. On the throttle body I loosened the top clamps on the right side of the engine because they were easier to reach for me. The thermostat was stuck wide open.
I just had to go through this procedure, not to replace the thermostat, but to replace the two short hoses that connect to it. I took the bike out for a spin the other day and parked it in the garage, came back out about two hours later and there was a nice puddle of coolant under the bike.
I stripped the right side plastics off and discovered it was coming out of a frame hole located under the thermostat. I pulled everything off to find the two shorty hoses looking like Oprah on a fat day, they were really soft and expanded. The end of one of the hoses was nice and wet, so I figured the coolant was getting by the clamp as the hose expanded.
getting those new hoses(not factory ordered)back on there was a pain in the ass, i got it buttoned back up within 2 hours of starting...all is well
The coolant hose connecting the two rads on my bike feels soft but I've never felt a new one. The bad is these are thin walled and this hose is long so I think even a new one will still have a soft feel.
I just did my thermostat tonight, well I have to put the throttle bodies back on yet. I didn't even remove the tank or disconnect any fuel lines. I propped the tank up with a piece of wood in the front, swung the throttle bodies out to the side and sat them on top of my shop vac(happened to be the perfect height, and in my garage at the time) The location of the t-stat wouldn't be so bad if they didn't go bad like guacamole sitting in the sun. I hope the new one lasts longer than 13k miles.
Nice! I had a dealer replace my thermostat because I was busy . . . er, I was going out for dinner, and . . ah . . . . I was in a coma at the time. Anyway, it didn't cost very much in shop time, BUT the mechanic pinched lines when replacing the fuel tank. It was a big annoyance. I should have done it myself. Thanks for the pics.
I usually slice the hose then pry the screwdriver around the housing. When it corrodes up after many years they bake together. Usually need a new hose anyways since they get hard and it's going in the trash. Wouldn't want to blow one of those hoses in the mountain. Russ

bad news usually as oil leakage from a head gasket, or oil passage swells coolant hoses from the inside out. Russ
Quick tip use dishsoap for easier rubber hose installation, does not affect the rubber, spit works good too.
The thermostat on my newly acquired 2004 VFR is apparently stuck open. In 75 degree weather the bike isn't getting warmer than 163 degrees. I think that the bike takes too long to heat up. In the parts diagram for the thermostat the part number and nomenclature is 37760-MT2-003 SWITCH, THERMOSTAT. Is this the correct item to order along with 91307-PH7-660 O-RING (13.5X1.4)?
I had some temperature problems with my 2002-model. Even in weather around 15°C (59°F. Yes, that's warm here) the engine temperature quickly dropped to 60°C (140°F).
Thanks to the good instructions provided in the thread, I managed to replace the thermostat. Now during one night I drove home when the temperature outside was +3°C (~37°F) and the engine temperature stayed above 74°C (~165°F).
Thanks for the excellent post.
As I have said before it was really stupid of the manufacturers to sandwich the thermostat between the carbs and engine.
Be glad when they get motorcycle people back in the design dept. instead of computer designers.
The VF 1000R put the thermostat where it belongs . In a easy to get to location.
Agreed, with all the plastic on the bike they could have mounted it in a better spot.
I have to rip down my 6th gen this weekend to replace mine.
Sorry to hear about that.
I have always had this rage fantasy where I create a movie, and in the movie I go find the actual designer or person that made that decision and kidnap them to come actually perform the repair so they can REALLY understand the grief they have cause thousands of people. Of course I have them call home and let people know they are working so the authorities do not go looking for them.
Just a fantasy.
With the thermostat not working on a bike with only 14,600 miles on it makes me think that the thermostat was not really designed/made to last.
