I need to change the cam of my 91 mod 735. Does anyone have any experience with a sports cam. Will it give more power, and how much ?. What will it do with the engine, some bad experiences ?. The price is not that different, US$ 200, for an original, US$ 450 for a sports cam. Prices are for just the cam, from Motornord in Sweden. Hope someone could share their experiences. Excuse my bad english !!
