Question about BMW Motorcycles
Posted by Anonymous on
A lot of carbon build up inside the cylinder can cause this. Try running seafoam through the engine.

Make sure your fuel tank vent is not plugged. To see if this is the problem, the next time the bike starts acting up, stop and open the fuel tank. If you hear a whoosh of air being sucked in you know your vent is plugged.
The C8HA is still available, it is NGK stock number 2168.

I am going to have you do a series of things to clear up the problem. First come the basics >
Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new STOCK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Don't be cheap, use a lot of cleaner. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean and dry the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw. This process should get you back on the road unless other problems exist. Let's say that the bike is no better >
There isn't much more to do. You just rebuilt the engine.
Please rate this solution. Thanks!

This sounds more like a lean fuel condition than ignition. If it was stored over the winter without the gas being drained or a fuel stabilizer being added, you'll likely have varnish build-up in the fuel system that is not allowing sufficient fuel flow. If your engine is fuel injected, it's likely your injector is partially clogged. If it's carbureted, your carb jets may be partially clogged or your carb float may be sticking and not allowing the needle valve to fully open. Fill the gas tank with fresh gasoline, but leave enough room for a can of Sea Foam. The Sea Foam may be able to break up the deposits and allow fuel to flow again. However, there's no guarantee and the fuel system may have to be disassembled to be cleaned.

It's an engine safety mechanism, to shut down the engine when rpm goes beyond 10K.Even you are travelling at 140Kmps rpm won't reach 10K in normal case.Probably you have to change vacuum piston kit to resolve the issue completely.
