Webers, once set up properly, will be rock solid reliable and have many performance advantages including better throttle response, more HP and much smoother idle with a big cam. If you find a retailer with good customer support I wouldnt be the slightest bit nervous about upgrading and getting them tuned. If you want a second opinion on a good baseline setup PM me with your engine specs and I'll get some choke/jet/etube combo specs from someone who can tune webers in his sleep.
