The UT2 coils (4 wire) can only be used with stock flywheels. If using a billet flywheel, you must run a UT1 style coil (single wire). Chinese engines usually have UT1 style coils already. However, some Lifans and 420s have a digital ignition and will need a Honda UT1 coil to run the billet flywheel.\u003c\/span\u003e\u003c\/span\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eIf ordering for a 301, be aware some engines have large cam journals (.6357), but most 301s have standard cam journals (same as GX270s).
