i have a gilera runner which runs fine but when you ride for about 5 mins the temperature starts to rise i put coolant in there with water and it still keeps going up and down. its causes my bike to slow down and only ride at 20mph can any one help
bad connection or broken wire to the little sensor thats screwed into the cyl head!!! ive had the very same thing happen to me
ok mate thanks for you help i have stripped the bike down and im going to look at it early in the morning. just one more thing the coolant liquid do you have to mix it with water
yeah just use car antifreeze/summer coolant mixed 50/50.... people think i will just use plain water as its summer, but antifreeze has chemicals in it that helps keep the water ways clear and raises the boiling point of the water... in short use antifreeze all year round
