Billet Aluminum flywheel recommended. Stock flywheels, esp "Clone" are prone to failure and very DANGEROUS
Note: UT2s series Hondas (2012 & up) have Rev Limited coils and will require a new coil to exceed 4000 rpm. The UT2 coils (4 wire) can only be used with stock flywheels or 6693 ARC flywheels. If using any other Flywheels, you must run a UT1 style coil (single wire). Most 390 “clone”, 420s, and 460s have UT1 style coils already (However some Lifans and 420s have a rev-limited digital ignition)
The difference in the Kits is the main jet. We recommend you check the check your STOCK main . If stock main is a :
· #92 thru 97, use a UT1 kit,
· #98 thru #102 use a Hemi Kit’
· >102, Use a UT2 kit
Manufacturers have been know to use different jets on the same models. So it is important to know the stock jet size
