Rc51:D will not start, changed out fuel filter , spark plugs, oil change ,pulled injectors and had them cleaned , still won't start.....Problem , fuel entering
1# injector and dripping down into left-side exhaust and out of the slip-on
joint.........The Fix......changed out fuel pressure Regulator............about
1 hour..... including removing the tank .......she started right up,

Good to hear she's running. :)
Looks like the pressure regular can fail either way, too little or too much fuel.

Now ,the next thing to do is have the bike re-mapped ,now all the crap is
out of her ,she is running a little rich...........

Glad you got it running.
