Hiya Reaper

Any more ideas on the noise? Does it increase with revs or does it increase with speed of the bike (coasting with the clutch disengaged)?

I'm betting on engine noise and that it's cause by a loose cam chain and/or too much valve lash (clearance) in one or more valves.

If you're used to water cooled modern machines, you'll generally hear more engine noises from your DR than your other bike(s). There are no water jackets to insulate sound and the cooling fins kinda vibrate like speakers.

Here's what I'd do:

I'd begin by draining the oil....and you'll need a new left side case cover gasket. (unless you're very very careful or very very lucky - maybe both)

.....then remove the left side case (trying to preserve the gasket if possible) When removing this you are separating a large piece of metal from the center of a large circular magnet so expect resistance. Try to move the case at 90 deg to the bike. The magnet makes this "interesting"

.....then adjust the cam chain tension See: http://home.germany.net/avehrenb/DR800maintenance.html

.....then adjust the valves See:
http://home.germany.net/avehrenb/DR800maintenance.html

Those sites will get you started if you require particular assistance for doing any of these jobs, you can get it here.

Maybe other riders can assist with sites with more complete photos but that's what I had on hand for reference.

It's basic service so dunno what you'd pay to have a shop complete the job in your part of the world. But.....the cam chain service is particular to this bike and not very common. So be certain the shop has a service manual or experience with the big DRs before letting them loose inside the left side of the engine.

For replacement oil, see the previous 10 or so posts.

If you found this helpful, you owe us photos (see, we've held you hostage already). For assistance with that (the photos) see: http://www.advrider.com/forums/showthread.php?t=919

Good....then I can also tell you to expect a few gears and washers from the starter motor gear train to come away with the left side cover (and some will remain in the main engine case half) depending on how they stick to the oil film.

It looks complicated at first but pretty much only goes back together one way.

Oil??

Hi All,

Good to brought up the oil issue i8lusaka, I wanted to ask as well, because there is a BIG debate on the Hungarian DRBIG Forum about the oils.

Lods of guys prefer the 10w-40 semi syntetic oil,but they reckon 15w-50 for the bikes with higher mileage. Someone likes the Mineral....

Anyone knows anything about the Texaco oils?

thanks
Gabor

My advice.
1)Keep to the viscosity the manufacturer recommends and switch to higher only when riding in hot places.
2)Use semi and change it often. Keep your changes to 2000km and you cant go wrong. Its better to use a little bit cheaper oil and change it more often than use an expensive and let it become tar.
3) If you feel compeled to use car oil, dont listen to the naysayers without doing some search before!

Rob,
I've a Scottoiler. One drip every 40 seconds at tick over. I adjusted my first chain 3 times and ran it for 25,000 miles (too much sideways slop). The second one did 15,000 miles (not OE and changed it 'cause I ran out of adjustment).

Engine noise

Hi ReaperX!!

Is the sound from engine similar to this?
http://www.youtube.com/watch?v=WqZkiTAJzX0

I had this pretty loud tictictic sound from the engine maybe half of the last summer, but that did not bother too much. My bike is spending wintertime in warm carage in other town so i think i try to find out what causes that noise in the spring. We have -15 celsius right now and had -25 couple of days ago so no ridin for a while.

Sad we have only just few centimeters of snow. I heard it has snowed today half a meter snow somewhere in the USA.

So all in all if the sound is similar and you find the right source let me know! Pictures of your bike wanted!

Any sugestions will be greatfully apreciated.
Many thx
The ticking noise may be the adjustment of the valve decompresor if is to tight or to loose I think from memory the front and back edges of the flat spot on the shaft maybe just touching the rockers if not adjusted to the right clearences as per manual.

I dont know for sure but when you first start the bike before it gets hot you may be able to put your finger on the end of it and see if you can feel any tapping by touching the compressor shaft
