Bike is going in to the mechanics tomorrow....

Here's the scene:

Monday night, ride home from work (50 'ish motorway miles), after I parked up. I notice that the overflow pipe by the left foot peg dribbled a little bit of water (probably about half a cup)

Checked the coolant level before going to work Tuesday morning, all looked well.

Tuesday night riding home from work, temp gradually getting hotter until it reach max, stopped at a set of traffic lights, just before I got home and 2 things happened:

1) the dash went into "disco-mode" changing from the normal display (with temp gauge flashing) to a pic of a thermometer to the F1 engine management warning, it kept cycling and flashing through the three screens.

2) steam pouring out the overflow pipe

Got the bike home and let it cool off.

Haven't used it since, checked the coolant level and you can see some at the bottom of the header tank, but way below the low limit.

The garage is only about 2 miles from my house so I should be able to get it there tomorrow without any issue.


To my mind I'm thinking its likely to be a blockage or an air pocket somewhere in the RAD or elsewhere in the cooling system that's forcing the water back through and out of the overflow - anyone else had this before?


Until this happened, I hadn't realised how badly designed access to the coolant system is! - Does seem daft that to top up the coolant you have to remove most of the body work? or is there a trick i'm missing?

You can top up with out removing panels. I posted method some time back.

Looks like the left hand rad fan burnt out, and then the extra load on the right fan blew the fuse. Waiting for a replacement fan to arrive. :-(

[O.C.]

Hopefully that should mean a quick(ish) fix

Sorry forgot to post a follow up....

Coolant issue all sorted.

Bike was in for an extended stay, as I decided to bite the bullet and have a slightly shorter Hagon rear shock fitted at the same time.

Being only 5'8 the bike is now almost an inch lower, its so much easier to paddle backwards out of parking bays and off of my drive.

Very happy. :-)

Result!
