Welcome. The clunk when shifting cold is normal.

Telling us the year and model might help get better answers.
Like most motorcycles, the Spyders have a "wet" clutch that shares oil with the engine.
Because of that you can NOT use "plain" car oil in it.

The engines are of a "dry sump" design and the oil needs to be checked when HOT.....not cold.
It is fairly easy to overfill but nothing on the stick probably means that it needs at least a quart....of MOTORCYCLE oil.

She says last time she rode it, it was stuck in 2nd gear. So I'm assuming her spyder has a limp mode. Will let you know more tomorrow. Thanks alot

The "limp home mode" usually doesn't apply for transmission problems.
Is this an automatic or manual transmission ?
From what you have said, I assume automatic and being "stuck" in 2nd gear is a common symptom of low oil, I think.
