Sorry to revive a thread that has been beaten to death, but I just got a Busa shifter 99-07 compatible, and it does NOT fit my 2005 SVS. Every thread I found on here lead me to believe that it would work, but alas, it did not. It's like the threads on the shift linkage rod are off. I can thread the linkage rod on to either the new shifter OR the arm-piece that attaches to the shaft that runs into the transmission. And YES I know they thread opposite directions on the linkage shaft. It is as though one of the threads on the linkage is at an angle-the angled threads fit perfectly into my OEM shifter, it will not fit into anything else. The non-angled threads fit fine into the Busa shifter, but then the angled threads won't feed into the shift arm, and vice versa. Anyone have a solution? I checked and re-checked this a couple of times I am at a loss. I cannot get the Busa shifter to seat itself unless I put it on the wrong side of the shift linkage. I know this is a bit confusing, but I don't know how else to explain it. Thankfully, I bought the Busa lever as a spare, but I would really like to get it working, or at least figure out where I can get a folding lever that will fit my bike....
