What rpm is the engine running? If you are just letting the engine idle while in 2nd gear it may jerk back and forth due to slack in the primary chain. I usually idle mine up a little if I am just rolling around the beach or in town.

After I change the EHC for the wireplus the lights of the rpm keeps rolling from green to red in the 1 and 2, when I give gas and go round 60 miles/hour it begin to function normally.I try to adjust it but no changes.

If you are in 2nd gear and its jerky...... You must be going pretty slow. Put her in 1st and cruise a little higher RPM.

First thing i'd check if it's jerking back and forth in 1st gear is the primary chain adjustment.

Dude, as suggested check your primary chain. Several members here ride there bikes on Hawaii and all of us ride in town. Nothing wrong with your carburator being to big or small. And keep the rpms up, idle should never fall below 1000 rpm on these motors or you could possibly suffer from oil starvation to the motor.

Check out the "How To" section on servicing your Big Dog. It'll have all the info there and it's posted here in lots of other places. Easy to do
