Default runing on first 2 cylinders

Hey my bike seems like only the first two cylinders get hot when first running. Is this normal till it warms up? bad ground maybe clogged jets?

could be, and PROBABLY is a carb issue. check your spark and the plugs first though, they're easier than pulling the carbs off. if they work fine, your problem is likely in the carbs.

I would say weak coil but if its 2 inline cylinders then that would throw that out. It wouldmost likely be plugs, carbs, or valves then.

Use your tongue, it's more sensitive and will be more accurate.
