Sputhe was not known to me because I was not into the motorcycle racing scene. Looking forward to my next purchase from Sputhe. I was finally able to get the bike out and wow what a difference the stabilizer links make! On acceleration it doesn't feel like it's trying to kick me off any more plus the high end speed issues are gone and I can also notice a difference at low speeds.
Thanks for making a great product! Hi, l was just looking over my 04 dyna.As always, review your service manual before attempting a labor intensive job, such as this. Also, refer to your manual as you work. It is important to have a clean, safe area prepared for disassembly.

Next, loosen and remove the two bolts that retain your breather assembly; then evenly, loosen and remove your rocker arm towers. Label the towers front and rear and set them aside. Now, you can loosen and remove your lower rocker boxes. You are now stripped down to the heads. Break them free with one sharp motion; then continue to loosen evenly in a cross pattern.

Finally, you can remove your pistons from the connecting rods. It is important to slide short lengths of rubber hose over your cylinder studs for protection. Then, proceed by picking out the wrist pin clips and carefully tapping the wrist pins out from the connecting rods.
It is preferable to use a connecting rod holder when tapping out the wrist pins, if the tool is available to you. Harley top end overhaul is a lengthy procedure on your Twin Cam motor.
