Carburetor leaking fuel
As some of you who have read my other posts know, I laid my bike down a while ago and I am getting into the repairs.
I didn't fire my bike up for a while, so I was letting it idle to recharge the battery. I stepped away for a few minutes, and when I came back there was a considerable amount of fuel on the ground. I shut the bike off and wasn't able to identify exactly where the leak(s) came from. It's hard to judge how much fuel was lost, the stain on the concrete was about 1 foot by 2.5 feet. Maybe half a quart at most?
Part of the damage in the crash was a bent outrigger (footpeg/clevis mounting bracket), which has the fuel tank breather tube and carburetor breather tube clipped into it. To keep those tubes away from the exhaust, I had them tucked into the frame facing upwards (rather than downwards, which is their normal position). When I untucked them, maybe a 1/4 ounce of fuel poured out of them.
Here is my dilemma. In order to find out where the fuel was leaking I need to fire the bike up. However, I have read that if the carburetor is leaking fuel, its possible that fuel has mixed in with my oil. Obviously I do not want to run the bike if that has happened.
Is there a way to get some oil on my finger to smell it to see if it smells of gas? Forgive me if this is a stupid question, but it seems like removing the oil drain bolt is the only way to actually get at the oil, and I don't want to drain it. I tried removing the oil filler cap and sniffing, but it smells too much like fuel around the bike in general to tell.
What would you guys do in this circumstance?
Thanks for the continuing help, this community has already been a huge help on some of the other problems I am dealing with since the crash.
