2005 RX1
I have a 2005 RX1 and it will not rev up. I rebuilt the carbs, put on new O-rings, needle and seats, readjusted, synchronized them, and still won't rev up unless you put on the choke a little bit and then it will rev up but it will backfire and sputter like it's out of time. I checked the timing chain, timing chain did not move. I checked the coils with an ohmeter, and bypassed the throttle switch. I have also done a compression test and that's good. I also checked the fuel pumps and put new fuel filters in. Also cleaned out jets thoroughly.

Any help would really be appreciated. I have taken this apart numerous times and cannot figure out what's going on and how to fix it. Wondering if this could be an electrical issue due to everything else I have done listed above?
 

As mentioned above, I cleaned the pilot jets thoroughly.

Thats what they all say and when you need choke to get it to move its usually the pilots. I have done them several times and they still run like crap. Tossed and bought new ones and back in business.
