Ok, i bought my Raptor about a month ago,enginewise, it has a whitebros cam, GYT-R exhaust system, and stage 2 jets. It has the stock filter and airbox lid on... I would think that i could take the lid off and put on an aftermarket filter, but if i put on a different filter with the lid off.. would i need to rejet it....

 

Yes unless your running rich now.

 

I was thinkin maybe 155/160 jets, any comments on this??

 

If its Dynojets 155/160 you should be close if not one step more 160/165

 

I have heard that mikuni jets are way better than dyno, is this true? and/or what brand do u guys recommend, thanks....

 

I feel the Dynojets are the best and they have way better needles then the stockers

 

I think the GYT-R jet kit is better than the DJ kit but that's JMO.
