left intake from factory tight

1 post in this topic

This is my 2nd new 07 450,the left intake on my 1st 07 450 was .003in straight from the factory. Same with my 2nd NEW 450,07. The other 2 intakes were .004in and exhausts .008. which I do like to keep on the bottom of the tight side anyway. Just giving heads up no big deal,Yamaha likes to shim on the tight side.
