You'll need to give more information. What is it engaging at now? What color spring is in the drive clutch now? What weights are in it? Maybe you would prefer stock clutching in it?

It will engage lower being more trail friendly. Chek the plugs to see how it is burning fuel. If they look black, you can put smaller main jets in, also check oil consumption to see if the pump can be leaned. That will help with fuel mileage, I would say.
