Re: Full system on a 2002 R1???
What you have heard is BS... I have had a full system on my R1 since it had 150 miles... Yes there is some sputtering down around 2,000 rpms if you whack it, but I don't ride like that so it's a non issue.
But most of us won't be able to answer your question on the '02, no one has had them long enough to do the mods and find out the results.
