I have a 2002 Raptor I want to put a pro design air filter on it with the alumunim bracket in the air box. My question is do you have to re-jet for that mod. Iam going to run it with the airbox lid on for now. I just dont like the stock set up but I really dont want to rejet my carbs for now. Thanks

 

3sportman- if that is all you are going to do, you do not need to rejet. The current issue of dirtwheels/national enquirer shows how to pick up a couple of hp on the stock machine with 6 dollars worth of jets.

 

So this must mean on an efi vehicle you don't have to increase air to increase the amount of fuel,RIGHT.

 

Thanks for the info. I seen that in dirtwheels where they increased the horse power for 6 dollars that is a considerable amount when some other bikes are only getting that with full pipes and k&ns. They cut the hell out of the air box though if I would of did that tuesday I would of had a pound of mud in the air box. Is it that hard to rejet? I thought that I would get the pro-flow kit in first then rejet for pipe and air box. Thanks

 

Could someone give me the details of the jet mods from Dirtwheels?

I live in Australia and it is very hard to get any of the ATV mags as well as parts.

I want to rejet but want to get the right parts first, the nearest Yamaha dealer is 3-4 hrs away (I am in the middle of nowwhere).

I found a company that sells the Dynojet kit for Raptor but is is $200 Aus (about $105 US) which seems a bit pricey to me and the $6 dollar option sounds better to me. Do you think the Dynojet kit is worth it? Parts are VERY expensive here compared to the States.

Thanks

 

RaptorDownUnder,
Private message with all the details.

 

Actually, the Pro-Flow filter by itself does help throttle response, but more importantly, it secures the filter to the intake and it no longer depends on the airbox lid having a correct fit, as on the stock system. It is worth the piece of mind.

 

money aside, without the lid, which provides the most power pro-design's filter or k+n. or is there somthing better?
