Im upgrading to the fcr39 on my 06 SM. I bought it from TT store so im not sure if it was already modified with the oring mod or if it even needs to be.

I did the Merge AP spring after having the o-ring mod for 6000 miles and one year. The o-ring was in bad condition and split half way thru...I'm not sure it would have lasted much longer. The Merge spring was like $20 and I think well worth it to not have to deal with it again. To redo the o-ring would only be a 3 minute deal so not a big deal there either.

I just did the Merge AP spring instead of the "O"ring mod so I don't have to worry about it:thumbsup:

To install the spring, the carb really should be removed. It could be done on the bike but, it may be more difficult and frustrating if you try to. I for one, would never try to do it on the bike Buck up, get with the program. R&Ring the carb is good for you, builds character.

However, doing the oring on the bike is a easy, one minute job.
