Jetting / DG Steel RCM EXHAUST for a Yamaha Tri Moto 225

[acidtuch10]

Does anyone have an idea on what is the recommended carb jetting for a DG Steel RCM EXHAUST for a Yamaha Tri Moto 225? in upstate NY?

Thank you
Dave

Best bet is to buy a handful of jets larger than stock (Pilot and Main) a few spark plugs and start tuning. 3 people with the same motor, air filter, and exhaust can all have different jetting.
