I personally don't bother with that kind of stuff. I just change the oil every 3kish. I would be prepared to run into a few issues that may or may not pop up from sitting. Its up to you though.

 

I plan on replacing the tires and getting a bike lift at harbor frieght...

 

Thanks for your input I wont get one...

 

I pretty much agree with what Yamaharley said. Oil probably in the crankcase. Only difference I would do is put 1 quart of oil in just to be sure. Once it all pumps up into the tank you will be changing it out anyway.

 

Thank you so very much

 

Don't forget to give the carb a good cleaning too, 13 years is a long time without gas through it. You may want to open the primary side and I think you'll find the oil you lost, they have a tendency to drain into it. Have fun with it.

 

Thanks any tips are greatly appreciated

 

I wouldn't add any additional oil YET.

I would pull the spark plugs and crank the engine over for 10-15 seconds a few times.
Then I would check to see if any oil returned to the oil tank.

 

Adding oil can not HURT anything with the exception of a possible oil overflow out of the tank. I personally would not chance cranking/running with NO oil. But to each his own.

 

I personally wouldn't crank it over if I wasn't for sure that it did indeed have oil in it. It may or may not have oil in the case. It'd be worth the couple minutes to drain/catch the case and refill with the proper amount of oil. My 2 cents. Take it for what it's worth.
