Possible overheat on exhaust
« on: July 13, 2012, 06:21:45 PM »
Hi Chaps

Any ideas on this - 2008 K8 water cooled.  The bike engine is right temp after affter a short ride - no warning lights, oil levels good, coolant level good, but...... I get a strong smell like overheating coming up.  Difficult to pin point.  Smells like paper when it scorches or a very hot iron when paper is put on it.  No labels on anything, no dirt on manifolds BUT ....... the exhaust can is getting very ...... like VERY hot.  When I sniff down the end, it smells like what I've described.  I read once that someone with a Honda CB600 had a poor fuel mix and it blued the pipe/can.  Now I look - mine could have a slightly pale yellow tinge - not clear stainless silver.

What do you reckon?   :icon_scratch:

So not new then...
New can or original? Someone hasn't stuffed something down there while parked possibly? Investigate with torch.

standard can - I'm reasonably sure nothing poked down it as rarely left on its own.  Garaged.  The surprising thing is the end part of the can is probably hotter than the black section at the bottom where it joins the stainless.  May call the RAC out on Homestart and see if they have got any ideas, if not got a very good local mechanic.

Ok, how many miles has the bike done? This sounds like a reasonably new bike hotting up. Mine still smells like it's getting hot, and it is.. If you're not getting any smoke and everything else is normal I wouldn't worry unduly..

If you're worried about rich running check your air filter isn't dirty..

I wondered that, but it is a 2008...

Cheers Chaps - thanks for the advice.  Got the RAC out for a Homestart to check temps - all OK - fan was coming in at 103 degrees which was exactly where they expected it.  Seems that the can does get very hot on some bikes.  I took it for a spin for about 20 miles and on checking the can again it was noicebaly cooler than round town!  Still got the smell on occasion but RAC said bike appears to be as it should be.  At least I'm happier now I know I'm not burning the catolytic or something stupid.  Will check the air filter - bike has just done 3900, but was services at 2400 just before I bought it in May.

At 3900miles its still barely broken the engine in dont worry about the air filter it will be fine unless you have done all those miles on dusty farm tracks in which case get a vid up

Lol Ian..

The smell is because it's new, 3,900 miles in 4 years is pathetic, a right result for you though.. :)

Makes you wonder why folk buy bikes to do 1000 miles a year, that's just a long weekend really.. It makes folk who actually put miles on their bikes look like high milers, and that looks bad when it comes to trade in time.. :(


'Trade in? Yeah sure, what have you got? What year? And mileage?? Oh, you haven't actually been riding it have you? Well that will put the price down sir..'

Polishers make the rest of us look bad, ride your bikes FFS!

I agree, the bike is 'new' so it smells that way. I assumed that a 2008 would have more miles on it too...  :headbang:

To be fair my dads bike is a k8 and its only on 5.5k (had only done 1000miles when he bought it at a year old) but thats due to a number of things least of which is his shoulder gives him problems if on long rides but it does mean that when mine does eventually go tits up I'll have a virtually new bike ready and waiting  :laughing7:

Bloody hell, that was a proper bargain wasn't it..

2,400 miles in 4 years? I did that during last month, i'm not joking either.. I wonder sometimes why these folk go to the expense of buying, insuring, taxing and MOTing a bike to have it sat in the garage for months/years on end doing nothing..
