Re: fuel in oil
1a. Ditch the stock fuel tap and replace it with an aftermarket item that has a true 'off' position.
1b. Replace the float seals in both carbs.
The combination of leaky fuel tap and leaky float seals, along with the unfortunate coincidence of an inlet valve being open, are the cause of the fuel in the oil.
2. Dump all the oil and replace as soon as possible.
3. Hope that running the engine with fuel diluting the oil hasn't destroyed any bearing surfaces.

Re: fuel in oil
in addition to the above
you should clean the carb float bowls. The float valve should stop fuel coming through the carbs when the bike is not running but there could be dirt under the valve or the vale could be worn

Re: fuel in oil
thanks for the replies Does that mean the fuel in the oil made the bike run red hot and rough then not want to start or is the timing an issue to cheers

Re: fuel in oil
You should also check your fuel pump, when the diaphram fails, it allows fuel to enter a cylinder via the vacuum line.
I have had to replace the oil twice to ensure the fuel was completely removed.

Re: fuel in oil
If it was previously running OK and you have not made any changes to the engine, then the timing will not be altered. How could it be?al22 wrote:thanks for the replies Does that mean the fuel in the oil made the bike run red hot and rough then not want to start or is the timing an issue to cheers
