  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

449 getting hot

My 449 has never missed a beat just been serviced by dealer and out for a ride today coolant spilling out of the overspill don't thonk the dealer changed the coolant but will find out tomorrow.
Anyway just kept topping it up all day only taking 200 ml a time but chucked some rad weld in at the garage just in case, the fan didn't come on at all although the water coming out was boiling so routed the live wire direct to battery so on all the time?
Got home fine and the bike was fine all day
Anyone had the same or can help I off to Spain trail riding for a week next week and need it sorted please
 
Sounds like maybe a bad temp sensor or bad fan. Test the fan with some direct power to see if it spins.
 
yes still overheats with the fan on constantly spoke to the dealer who didnt touch it when the service was done he suggested changing the rad cap (he said have replaced 2 or 3 or could be head gasket!!! but hasnt had one go yet) which i did (have a terra as well) and seemed fine so ordered a new one will drop the coolant and refill with new coolant only takes a litre or so anyway and hopefully that cures it
 
just for info the fan wont come on until gets to 94 degrees so seems to think a faulty rubber or spring on the cap as fan still working but you will hardly see or notice the fan on anyway unless under constant real strain

If the bike overheats with the fan on constantly (wired to be on all the time), I would suspect the head gasket. If any of the head bolts gets loose, it allows combustion gasses to damage the head gasket with seepage, then, once it makes it all the way thru to the water jackets, then overheating starts.
 
However, a bad radiator cap will allow boil over even though the engine is in normal heat range. If it won't hold pressure in the system, its a goner. Put a new cap and some fresh coolant before you get worried about expensive things. If the oil isn't milky, there is little chance of a bigger problem.
 
new cap should be here tomorrow coolant drained flushed and fresh silkolene in just need a cap, however if it does it again then off to the warranty man!!!
ps oil is fine

Actually, my head gasket was leaking and there was no milky oil.

A leaky head gasket does not necessarily lead to mixing of coolant into the oil, it leads to mixing of combustion gasses with the coolant (over-pressurization of the coolant system and overheating) and/or allowing coolant into the combustion chamber (white smoke from exhaust pipe).
 
The 449's run very hot normally, especially if you do not carry sufficient speed to properly cool the radiators. The fan is only there to help intermittently at stops, turns and signals.
 
well new rad cap arrived started run upto speed and bingo no leak and fan kicks in just fine yipeeeee
thanks for your help
