Hi guys. This might be a dumb question but I went to change the oil today on the 950. I just bought a kit off of cf moto parts. The filter I was sent was a hi flo 152. The oil filter I took off has a spring in the middle down on the inside. The hf152 does not. Is it missing it or just a different design. To be honest I don’t know where the last filter came from. It was given to me.
