Re: Main 30Amp fuse blowing
Are the all fuses at their OEM size? There isn't much that isn't protected by fuses smaller than the 30 A main. So it points at a short somewhere, ex. on the R lead from the starter solenoid to the R/R, fuse box, and ignition switch. You could try removing the FAN, HEAD-LO, and HEAD-HI fuses and checking to see if things improve. Just keep an eye on the temp and stay away from situations where it would get hot (pull over if it goes above 225 °F).
There shouldn't be any dead spot. Your ability to go to higher RPMs tends to rule out a clogged fuel filter unless you're somehow also backing off on the throttle. Make sure that your kickstand switch isn't being tripped by a weak spring. Do you have an EXCVA? I guess it could also be the secondary throttle not opening correctly.
