I am cosidering putting an ESR 310 power kit on my 85 250r does anyone know how much of a difference this will make. Will I get a lot more power? It is around $900 so is it worth the money? And I do almost all my riding at the dunes and climbing hills I think the 310 kit should help a lot but I need some input.

 

Before you go out and buy a new one you should check ebay. There is a duncan PC2000 power valve cylinder on there right now for a little over $800. That is a $1500 cylinder. I have heard very good things about ESR. I hear that the 310 kit really smooths out the powerband and makes the trike even easier to ride.
