WR450 Gas in the oil?
Posted January 08, 2006 - 05:50 PM
I have about 200 miles on my 06 wr450 and have done all the free mods (except the grey wire) and the jd jet kit. The last 2 times I have changed the oil I have noticed the oil level was very high and smelled of gas.
I asked the dealership about it, and they said that the petcocks on the yamahas are known to leak and may be flooding the engine and the fuel is mixing with the oil.
I checked the petcock and dident notice it leaking.
Any ideas on what would be causing this, and is it dangerous for the bike?
I was reading the posts on the grey wire and how it changes the timing to allow for the change in the throttle stop. Could having cut the throttle stop without cutting the grey wire be the cause?
Any help or ideas would be most appreciated.

I always turn the gas off, and usually turn it off then run it for a few moments to get rid of some of the gas before putting it away.
Any other way it could happen or any idea on things to try.
I was thinking of disconnecting the fuel line while not in use.

The dealer has admitted there is a problem, get him to fix it for free, is it under warrenty?

Regardless of whether your petcock is on or off, fuel should not leak into the carb and therefore the engine. The needle valve and seat's only job is to control the flow or completely stop the flow when the bike is running or not running. Although it is good practice to turn fuel off when you're not riding.
There is absolutely no chance that the JD Jetting kit or the needle jet will effect the seal of your needle valve or let excess fuel through while not running. However, it is a possibility that whom ever fitted the kit may have damaged or upset an adjustment.
