has any one had a problem with installing an open air box (pro design) filter in a raptor 660, and having to jet the carbs?.. i put the new filter in took off the lid and the bike bogs out on top end like 3/4 of the throttle open. i had a banshee and installed the same mod but never had to jett ?

 

If you let more air in you must rejett, or risk running lean and burning it up. You atleast need to bump up your main jet a few sizes.

 

you definetly need to get a dynojet jet kit(pretty good instructions included.)

 

Oh yhea if you are going to put a pipe on the raptor then I would do it before you rejet that way it will cut down on the amount of times that you will need to rejet the carb.

 

thank you for your help whats a good jet kit?.. also im looking to change my cdi any thoughts or sugestions on that?.

 

It's jetting. Your main jet.

 

I would look into the Dynojet kit due to it coming with instructions and a larger selection of jets to tune with.

I just installed one and I put in 160 and 165 mains from the stock 140 and 145 mains. It runs perfect.
