I read the main ingredient in carb cleaner is MEK, it is also found in lubricating oils? But keep in mind you have a wet clutch and some oils are not recommended for that set up. That ingredient found in lubricating oils would likely be called detergent oils? That would not be recommended for your situation, you do not have or need MEK in your oil and should get your new filter and flush that stuff out.

I am just not sure, it may not be an issue?
