jet kits

[midnightjoker27]

hey guys sorry for another jetting question. i want to buy a jet kit from jets are us and they have 2 for the 450r carb sizes as follows.
the first is 160, 162 then up to 195 in increments of 5.
the second is 160-205 in increments of 5.
my mods are as follows:
416 11:1 wiseco piston, full hmf comp series exhaust, hotcam stage 2, 05 450r carb, uni filter, cfm airbox with lid.
i ride at about 800ft elev. so do you guys think i wil need up to 205 or should i just get the first one. sorry for the novel but any input would be appreciated.

You won't need anything over a 190, go with the first kit. Btw that kit is for the 04-05 450R carb. that has a 42mm bore, which is what you have and want. The other is for the 06+ and they have a 40mm FCR carb. Idk if the jets are the same but that is why there is 2 different kits.

Ya you should be fine with the first set to 195.

I would start with the 195 and if you can still rev out fully I would leave it in there and let it ride:cool:
