I installed them on my '04 Suzuki SV650. I didn't buy their replacement dampner rod set, just modified my own, which is fine. Their instructions for the SV said to increase the size of the holes in the rod and that was it, however they work much better if you braise or weld the small 1/16'' hole as well. The replacement rods they sell do not have this hole either. I didn't have any problem removing the rods, although I heard other people have issues with them on the forum. Socalsvriders.org is the forum I used to frequent that has a lot of great info on the cartridge emulators. They did work great and made a huge difference in the compliance over bumps in corners. I went with a .95 spring and 15wt oil. I weigh right at 190-200 and used to run it on the track as well. Going with just the springs won't do them justice. Spend the extra cash and do the entire set. I only used hand tools and a front stand and finsihed the job in a couple hours. The hardest part for me was cutting the spacers with my hacksaw. Don't do this, its a PITA. Use a band saw. If you have any more questions, please let me know. I'm not an expert, but I am very familiar with these.
