does anybody out there knows anything about R1's I'm having problems with code error 33

If you have continuity from the coil to the ignitor, the problem lies within the ignitor. The coils function by having a constant battery voltage on the red/black wire (you'll notice that ALL the coils have a red/black wire) - the primary windings in the coil charge up, until the ignitor "grounds" the colored wire (grey and white in the front, orange and yellow in the rear). As the voltage in the primary winding drops, it creates a strong magnetic field - the magnet (laminated iron) in the center of the coil charges the secondary windings, and the very high voltages generated fire the plug. You've already determined that the voltage on the orange wire is higher than the voltage on the yellow wire; that could only be because the orange wire is not being "grounded" on a recurring basis by the ignitor. (You have to remember that the meter you're testing the leads with cannot react to changes in voltage nearly as quickly as they happen; to really "see" what's happening at the coil, you'd need to use an oscilloscope).

Testimonial: "Thanks, the problem was the ignitor. I replaced it with a new one, and the bike works fine. Thanks again."

It is possible that the "brain" cycles the exup valve as part of the start up process.

are the cables in the right position to start with or the valve may move back when motor is warm

SOURCE: It appears the polarities on my original 2008

Had the same problem, the battery does not sit upright, therefore poles appear to be reversed, battery must be installed laying on side enabling you to connect the red wire to the positive. Dont connect battery to wrong poles this will blow the 50amp fuse and possible other damage
