Hi , I was wondering if anyone can tell me if it matters about the colour of coolant I use when I change coolant. I am currently in a remote area that doesn't have a great deal of choice of stuff like that , unless you buy 10 litres of it.........the 2011 Yamaha XT660R has the red coolant in it at the moment , from factory I guess. I know that the colour means something specific about the characteristics of the coolant. I have had the bike for a few years but it has done less than 500kms.....( haven't been able to ride it for a heap of reasons) ....anyway it has sat around for a while and I want to renew the coolant....( also because it seems to run hot....maybe lean ? ) The header pipes will glow red after a minute or 2 of idling and I worry that it is getting too hot. ......( mostly noticeable in low light conditions) ....Is it true that it is is recommended to change the coolant after 2 years , regardless of km up? Can anyone confirm that I just .....1. empty the reservoir, 2. drain fluid from the bolt on the water pump casing 3. flush with water 4 . replace with the required amounts in radiator and reservoir ...1lt & 0.25lt respectively 5. run for a while and check for levels ????

one more thing ....if anyone can help......will it hurt to put a bit of injector cleaner ( Wynns or Nulon) in a full tank of fuel if I suspect that I had some fuel in the tank that was in there for a long time....could some blocked / dirty injectors be contributing to a "lean " running bike, keeping in mind that it is has done only 400 something Km in the 2 years I have had it? Yeah, I know....it is next to nothing.....long story!
cheers if anyone has a chance to comment on this...I'd appreciate hearing from anyone......Mick
