For the experts i would like to ask what is the effect of a sport camshaft on a stock 500 engine with or without a 28 carburetor and also what can someone expect for a 540/camshaft/28carb. Is this modification worth?
Thanks for the info. So I purchased some new 540cc pistons and after looking at the camshaft was not going to upgrade it. But now after having it all apart, I was thinking I might as well upgrade it to a sport cam (passione500 has one that goes with 540cc that is a 35/75). If I replaced the camshaft and the crankshaft isn't worn then new standard crankshaft bearings would be ok?
Also, now that I am thinking about the camshaft upgrade what else do I need to change or be concerned about?
