    Throttle lagging under 3000

    I have a 78 650 special with mikes commando exhaust, uni foam filters, and VM 34s. When riding it will take a good bit of throttle to get up to about 3000 rpm and then after that it takes off. Would one of those torque inserts be what i need? It also has trouble getting past 5000 rpm any ideas?
