traffic was a beatch going from fulham up towards the a4 and was hard pressed to make it through even on the svelt r1. Lots of coaches and heavy goods vehicles had joined the party and were sandwiched together
fans were on at 103-105 degC but kept on slowly climbing until i was looking at 118 and heat warning lights were on. forced stop twice to let it cool down with the fans and engine off. was beginning to get worried as obviously that will chomp through the battery.
once i could get moving again and keeping a big more regular speed going the bike was fine.
whilst today is far from cold its not exactly hot today. coolant levels are fine. Something i’m missing here? never had any of my bikes do that before.
What year R1? My 2009 ran much hotter than my 2004 and 2006 bikes.Still, if the warning lights came on then I would say it must be a problem. You’re not using just water as the coolant are you?
Had a bit of a play with it on sat. Topped the rad up and made sure the rad cap was firmly sealed. Ran it hot and didn’t stray above 105 before cooling down.
So either it’s an intermittent prob or maybe just airlocks/lack of coolant in the rad/pressure seal was off and that did it. No apparent leaks.
Check out behind the Clutch Basket, there’s a sprocket back there that runs a chain onto the oil pump…this also drives the waterpump …If the sprocket is walking of the splines it’s your problem…
