DTR Problem (UPDATED) Need Advice ASAP.
Permalink  
 

Well ive noticed recently when i come to a stop my bike is leaking coolant just under where the stand is, i have to top up the rad every morning and evening before and after work.

 

Ive taken the thermostat out - still same problem

i checked the water pump was ok and its fine and turning.

 

i had the head gasket done around 1 month ago, if it was head gasket wouldnt there be problems stating the bike ? or any particular diagnosis for it?

 

the Expansion tank is FULL but the rad is near enough empty at the end of a ride, so maybe too much pressure ?

 

As you can see im confused and need some help fast before my bike blows up =) 

 

All Help Appreciated !

well clean everything and dry it and try leaving it on tickover to find the exact leak. sometimes leaks are missleading

do you blead the coolant every time you refill?

pics will help

I don't bleed it off everytime i refill it as im constantly refillng it, when its on tick over it doesn't seem to be leaking just after ive been riding it and e.g stopped at traffic lights or something.

What you guys thinking it is ? or could be ?

Thanks

Always go for Yamaha geniune parts yes its more expensive but will work out cheaper in the long run and less hassle ESPECIALLY when it comes to any gaskets on your bike

I used to buy all my gaskets from the nearby Yamahaha dealer, wanted to charge me £15 for a cheapo headgasket or £9 for a genuine Yamaha gasket.. Guess which i went for?
Oh and to be honest i've never used any sealer on my head gasket, just got the head skimmed and tightened each bolt to the recommended setting..
