he says he did gearing change, with intake and exhaust, so I wonder if he changed the internal gearing?

metal's build and mod threads should be on the site here ... same user name as his youtube ...

At the time, i believe the gear change metal mentions is from going to a taller tire and not from changing the sprocket.
