I just extended swingarm on my blaster about 3 in and my buddies are telling me I'm going to loose alot of torque. The only power mod a really got now is a dynoport pipe. I ride alot at the coal mines which involves alot of hills, being the the reason the got the swingarm. So my question is should I change any of the sprockets to try to regain some torque or would it be dumb? Any performance mod recommendations?
