I would start off by changing all four plugs first. but it has been known for '99 - '01 stick coils to go bad more frequently than any ther years.

WHEN CHANGING THE PLUGS, DO THE WIRES GO 1234 OR IS THERE ANOTHER CONFIGERMNT?


You got the wires right, but the coils might be off, I think the 1 and 4 and then 2 and 3 fire. Something like that. I don't know for sure. I'll send you the site. Hope this helps.

On a bike like the R1 that uses 2 coils to run 4 cylinders, most always 1 and 4 run off of the first coil, and 2 and 3 run off of the second. Both cylinders run buy the same coil fire at the same time, even though they are not both on the power stroke.

The motor will still run with the leads to the coils reversed, but runs much better when they are on correctly.
