Do i need to rejet the fcr mx if I add the Yoshi RS-3 full exhaust system?

Yes, If it was jetted properly for the old set up then you probably just need to go richer on the main

Get the FCR from Epic motorsports / Sisneros Speedworks and he will jet it for your exact set up before it gets mailed to you.

I've got a full Yosh RS2 on my DRZ400SM. The stock carb has been jetted for sea level and the airbox modded.

Will the jets supplied in the thumpertalk kit match up with the RS2?

Carb comes standard with the following:

- 200 Main Air Jet

- 160 Main Jet

- 45 Pilot Jet

- 100 Pilot Air Jet

- EMR or EMS Needle
