When i say coolant leak, I mean that one of the hoses wasnt tight enough and noticed some leakage so I just tightened the clamp screw which stopped the leaking... could that still mean trapped air then? Ive had a look in the manual and nothing on bleeding...

as ive just replaced the coolant today, could I drain the coolant and reuse it once ive replaced the stat?

ah thanks so much for your help. much appreciated

i suggested stat as its the most common cause of overheating, , and the easiest to eliminate, just remove from water jacket, suspend in warm water, on string, then slowly heat water with a thermometer in it, note at what temp the stat 'opens', you can see the bi-metal move?, if thats ok , then u can investigate more serious options? ok thanks sorry to be a pain but could you explain it as you would to a child because this does not make sense to me (im not that mechanicaly minded sorry lol) whats the 'water jacket'?

whats the cheapest option to eliminate first? buy a new stat, water pump or them test things?

fan will still come on if stat is not opening/closing as it should???, temp sensor on the rad will make the fan kick in???, i.e: rad coolant becomes hot because the water is not circulating through the water jacket, and the fan alone can not cope alone with cooling, as there will be no /or little circulation checki the thermostat this is what i thought... Will the stat be fairly easy to replace you reckon? its either that or the water pump as whitedevil said. ive already got sufficent oil and coolant. hope it nothing more serious

ok thanks, whats a 'leak down test' and a 'sniff test'?

Unfortunately I’m not too mechanically gifted… does anyone know where the thermostat is located on the r6 and how I can replace it.

Hi all. Brought a Yamaha R6 2001 about a month ago and everything was perfect ...Now it has suddenly started to overheat. When it reaches 117°C the red oil warning light will turn on and the oil level symbol begins to flash. My engine oil level is fine and is at the maximum mark. Today I replaced the coolant because this was low and one of the hoses was leaking…. Fixed this, then went for a ride and still the temperature rises (to about 116 - 127°C on average) It gets really hot really quick. The temp quickly rises and stays between 113 – 127. When I ride, it goes down only a little (about 109) but when I stop at traffic lights or when I’m stationary the temp will rise again past 118. When it goes down to 116 the light goes away and the oil symbol stops flashing. The fan works fine as I can hear it switch on and I can see it working. I don’t know what else it could be. I don’t want to continue to ride because I’m scared I’ll blow up the engine or something. Any help will be massively appreciated. Thanks in advance

10-15% difference in abrasion resistance (Disclaimer: Hearsay, but i'm happy to use it for a figure until someone proves otherwise ). Leathers act as a splint due to their tight fitting. And i've come off about 6 times in textiles (up to and including just over 30mph), and not once have i regretted not using leathers. Maybe at the higher speeds - but i'm happy enough. fair enough dude

dude get leathers! you will regret it when you fall off!

well done mate

all the best mate. hoping to do mine in about 4 weeks. let us know how you get on. get some sleep

I brought some Aplinestars SMX plus boots from ebay last night for £100 only worn twice. But before I did, I went into J&S and tried some on. Highly reccomened that you try on first.

wow thats very kind of you thank you. Im waiting on a friend to get back to me about his one so I should be ok.
