WEll i ahve some 180 mukini mains.. think they should be good? i ave 155 and 160 dynos in there currently

 

180-185 mikunis should be a good spot too start (180-180 is not good). Keep an eye on your plug and what your engine is telling you while riding. Use the choke too test whether you could use more fuel.

Curious.. What exactly is the big deal with running a bigger size in the right carb?

 

The Raptor has 3 intake valves.....both being fed by the left and right carbs. BUT, the right side carb feeds the center intake valve more than the left....meaning it has a bigger port and more valve surface area too feed than the left carb. Hense the need for larger mains on the right side carb.

Makes sense.. But. what im wondering now still.. is HOw can u tell the differnce between a stock raptor carb jet and a Dyno Jet?

 

Motojoes i called them and they said they didnt sell mainjets that arent in kits i just need like some differnt size jets i dont want the needles and all that crap.. can anyone tell me a site where i can pick the sizes of jets i want (dynojets) and then have them sent to me or a number i could call?

 

I would call dynojet, they ship fast and sell individually.

 

Do you have to call them to get tehm individually because on there website they only sell it in sets.

 

So everyone else agree those look lean?
