foam filters?

Is the foam from a mc shop the same product you buy from a dollar store?

The reason I ask is my norton was running great I change the foam una filter with cheap, sprayed it with the una oil and my norton runs like crap.

Any experience with this?

thanks

Yes there are many types of Foam. I tried it as a lad, probably for the same reason you did.
It disintegrated quickly and filled the carby with junk. Throw it away, clean your carby out, get it running
again and buy the real thing... Is my opinion.
