Well decided to go with 103 build and stroker flat top pistons. Stock heads (for now), updated hydraulic cam tensioner setup. Decided to go with SE 44mm carb and intake too. But I'm having trouble deciding on cam. I am about 300 lbs and wife is about 105 before we even load bags up. We live near mountains so always going up and down hils. Was thinking andrews tw21 ??? Whats the opionion.
