Oil Leak

IT'S GREAT TO RIDE!!!! My new problem is a oil leak it seems to be coming from the oil fill tank (for lack of a better term) maybe the cap comes lose? has anyone else had/have this problem? should I put a new oil tank on her?
still having the backfire problem, after a long ride it needs to sit around 15 minutes or so before it will start. I can live with it I guess.
Thanks everyone for your help I have got so far, it has helped.

there is an O-ring under the cap for the crankcase, maybe thats shot. is the oil coming from the cap?. As far as your starting problem, Im sure a new maintenance free battery will cure your starting problems

Rubline covered the oil leak, definitely check the o-ring. I just added a chrome oil filler cap and didn't realize that it needed an o-ring until I noticed oil around the new cap. Checked the old cap and sure enough.

For the hot start issue, the maint. free AGM battery is a must, also you may want to invest in a multimeter and check the r/r and stator wires just to be sure. I had similar problems and started with the battery. That worked fine for about two days and then it decided to not start at all when I stopped at a store about half way to work one morning. After investing in an r/r and with a little help from the folks here I found that the problem was the r/r, I replaced it and no issues since. If it is either the r/r or the battery it could put undue strain on the stator, which is bad news. Check the verses for what to check and where on the r/r and stator wires with the multimeter.


Oh, I forgot to mention, the day that it wouldn't start for me at the store I had the backfire two or three times while trying to get her started. Some of the more technical folks here could probably explain the reason for the backfire, but I'm pretty sure it's related to a weak battery not turning the motor fast enough to ignite the gas leading to excess gas which makes the loud boom once a spark does catch....or something to that effect.

Good luck.

I smile 'cause I don't know what the h*ll is going on.

Just to make sure you dont mean the tank on the right side do you?
The oil is on the left side the tank on the right side is coolent.
I have seen people think that is for oil.

With having one loose bolt, it wouldn't hurt to go over the rest of the bike and be sure any others you can get to are all tight.

That's a part of the maintenance schedule many over look. It should be done at the first 500 mile mark with a new bike, then every 6000 miles.
