Question about 2005 BMW R 1200 CL

1 Answer

Blue smoke Got a used bmw r 1200 and finally got it running.....enough to see some blue smoke from the exhaust. Bike needs usual maintenance items but how much do I want to put into the bike considering the smoking problem? The engine sounds good while running (still could use a little carb cleaning) but the smoke concerns me. Is this common on Nighthawks? As long as I keep an eye on the oil, is it even anything to worry about?

Blue smoke is probably oil smoke, as you figured. Now, how long did you run the bike once you got it fired up? Did you ride it? I'm wondering only because if you just fired it up, seen the smoke and didn't ride the bike, the oil smoke could have just been oil build-up in the cylinders from sitting and could clear up with a few miles. If you did ride it and the smoke persists, then you probably have worn rings/scored cylinders/leaking valve stem seals. That can be overlooked if it is not too bad, and you keep an eye on your oil level, like you're thinking. If your using a liter oil oil every 100 miles or something, then you might want to consider a rebuild if you plan on keeping the bike and sinking a bunch of money into it. It all depends on the severity and your personal comfort level with the situation.

What type of oil should i use for my engine/gear oil / final drive for my rt 1200 08

First, you did read your owners manual right? The manual lists the BMW approved oils for your bike. It is also important to use the correct quantity of oil in the engine, this is listed in the manual too.

I use Castrol Syntec 20-50 for the engine and synthetic gear oil (90 weight) for the trans and final drive.

On my BMW 94 1100rs the oil was full, no longer than two months ago, it did leak at all and tonight i noticed i was not reading at all in the little circle window thing. I put in two qaurts and still...

You must check the oil with the bike level on the center stand is best.

Were you checking the oil with bike on side stand?? If so, your oil level is now much too high.

If it consumed two quarts of oil, you would notice lots of blue smoke from the exhaust.

Exhaust pipe comes out white smoke when start bike on side stand

Continuous or just for the 5-10 seconds.
If continuous you may have oil seeping past your pistons oil rings or valve guides oil seals.
Check your spark plug see if they are fouled badly (covered heavily and oily) or just covered by oil and sooth lightly.
If 5-10 sec it is normal as the engine is heating up there are normally a little oil seeping past the seals.

2001 dakar has 50000km exhaust is running very

garbage oil, maybe it wouldn't hurt to have the valves checked and adjusted. black smoke means oil is getting past the rings or the valves more than its supposed to be. clean the plugs often too.

Bike is smoking. Was not running for aprox 2+ years. Carburetor fixed and all o-rings replaced. Bike started and and is very heavy on fuel and is smoking. Please help

If it is black smoke you have not cleaned, adjusted the carbs correctly. If white smoke then you have oil entering the combustion chamber and or exhaust.

Black smoke and fouling plugs

The black smoke is a tell-tale sign your running rich , this is confirmed by your fouled plugs. Possible simple item: is the choke stuck on? If not I expect you'll need to dig in to the carbs, give them a good rebuild and retune them.
I hope this may have helped,

Changing the final drive oil on a 2006 r 1200 gs

I use a turkey baster and about six inches of fuel line. Put the fuel line into the final drive, then squeeze the bulb of the turkey baster and then put then protruding end of the hose against the end of the baster and **** the oil out of there. The final drive only holds a pint or so. My old K bike had an allen head drain plug, I guess the newer final drives have been "upgraded".
