You need three things to fire...compression, spark and fuel.

Have you done a compression test? If compression is OK then it's likely not a valve issue.

Are your coils properly hooked up? Left one goes to 1 and 4. Right one goes to 2 and 3.

Have you checked your plugs to see if you have spark?

If you have compression and spark then your problem is likely carburetor.

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
