• 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 The previous version was outdated and no longer supported.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!

oil leaks.

well got my first husky last night. 2004 te 450 took it out today and gave it a good inspection. fort of all the seller told me one of the o rings from the rocker cover bolts were missing. turns out 2 were and subsequently weeping oil. (I have replaced these with copper crush washers is that ok?) Now the plot thickens. the valves have just been done, but the rocker gasket also appears to be leaking! I know what your thinking, no big deal just replace it. however the base gasket also seems to bw leaking. I can't help but wonder how all these can be leaking. my worst fear is that the previous owner has cooked the motor and is all warped. maybe I'm just being dramatic. any input very much appreciated.
 
Its an 2004 in new bike terms that makes it 9 years old....., just replace all the upper gaskets/rubber cover seal, re torque the cyl.
Its most likely fine, the older twin cam motors are rock solid and a big plus is that the 2004 TE450 is counterbalancer equipped. Just do your upkeep and baseline the bike.
 
thanks mate that's reassuring. any idea what the torque settings are? I can't fond any English manuals or a parts fiche at all.
 
baseline- It's a new bike to you. Go through the entire machine and verify all settings, oil, carb, chain, hardware, grease, airfilter, exhaust, valve clearance. Basically give her a full service, over the top inspection to get yourself knowing where you started with her-baselining. This way you have less questions about what may or may not have been done before you owned the bike.
You start at a baseline reset of the original time to your 2wheels zero time.
Also different locations warrant more in depth inspection I assume this is a Yorkshire UK bike, moist area ridden, pay attention to water intrusion and bearing corrosion. Its a good machine (the newer ones especially 08 and on as usual are even better), in 2003 it won the world enduro championship with Anders Eriksson.
 
lol yeah you could say Yorkshire is moist lol. yes I will do just that. going to get the relevant gaskets check the valve clearances and go fringe there. already checked all the bearings and they're all good the front brake needs a clean up and new seals I think. not touching the fueling coz she starts runs and goes as sweet as a nut. thanks for the advise. any idea where I can get manual?
 
Fork seals usually leak due to dirt \ mud \ crude in the seals ...Remove the seals, clean the dirt, and stop the leak ...
 
thanks mate. if I'm stripping the forks though I'll just replace. they're only about £9. what are people's views on these neoprene seal savers?

Sure.. your seals may be very old and actually need replacing ... The set in my 08 TXC250 finally were changed after ~18,000 miles but were cleaned many times and this always stopped the leaks till a mud ride usually caused more leaks ...

And go ahead and look at that seal when you get it out ... Nothing more than a couple rubber edges held close to the fork leg by a couple small springs ...Probably will be just a small amount of grit in there somewhere causing the leak ...

I'd guess the seal savers would help wipe the mud \ dirt \ grit away off the fork legs before it gets pumped into the seal area ... This is not high tech stuff here ...
 
right folks back to my oil leaks. I've got a relatively bad one coming from the side casing. not just the clutch cover but the whole lot

so kickstart has to come off along with the oil line to the head. is there anything else and is it as simple as it looks as surely I'm revealing the very bowels of the motor? I'm a logical thinker but like to know what I'm getting myself into. as always any help appreciated
 
also verify your crankcase is breathing properly from the valve cover vent. Dont want to have pressure in the case.
 
seal savers are good especially win the muck where you ride. But like everything they need to be cleaned regularly as well. I always just washed them in the sink with soap then dried and reintalled them. (I stopped using them because is just mostly dry and dusty here not sandy/muddy)
 
where is the valve cover vent? this sparks ny interest as the leak seems to start more or less as soon as the bike is started suggesting pressure?

it is at the top right of the engine on the valve cover. That little black plastic elbow with a rubber hose coming off it.
 
sorry I appear to do a lot of talking to myself on here but I'm just getting to know the bike. I took the air filter out today. it's in desperate need of a clean (should have done this before riding I know) and behind the filter there is a small puddle of oil in the air box. I assume this is not supposed to be there? could it be that I ran it with too much oil for a while maybe?

atleast I guess this means it's not blocked lol.
 
No, no issue with some residual oil in the boot, lots of times just the oil vapor condenses as well as some splash oil migrates down the breather tube and sits in the airbox, its quite normal as long as your not over filled and have it pouring in there.
Most every racing machine (teams) simply overboarded the hose . I have done the same on most of my latest machines.
With exception I left my 08TXC450 hose in place and on the sometimes upside down crash the bike would make a smoke screen when restarted from the oil flowing out the tube into the intake tract. I prefer to have clean air in my intake tract rather than oil vapor hot engine air, but I did leave it alone on the TXC450 to keep things cleaner outside the bike.
I do install a breather filter (K&N type) just to make sure no dust or dirt get back up inside the tube/engine (on my 04TC450, 06TE450 and now on my 11TE310 (my TXC450 was the exception).
There is a "cyclonic" breather on the end of the cam opposite of where the breather fitting sits on cover, its simply a cam attached spinning disc that blocks direct access into the breather tube. The engineering intent is to capture liquid and oil vapor and fling it inside the engine so it doesnt go straight out the tube. Its a simple effective way to cyclonically recycle the oil while allowing crankcase pressure and vacuum to to be released as the piston and other rotating parts create pressure waves.
 
breather tube on my 06TE450, in wet places I would run it down below somewhere, also for less mess. My 310 hose and filter resides right up front under the exhaust header and behind the skid plate.
