IDS installed! A straight forward project; did apply a thin film of anti-seize on the mufflers joint and re-used existing torca clamps. All seems good! The brake caliper required some tight maneuvering; spread the pads with a 4 inch blade dry wall applicator, then just hand squeezed the pads away from the rotor. That gave enough wiggle room even though the pads were still over half new. Was fighting the rubber damper on the caliper when re-installing on the weldment; Applied some 50/50 isopropyl/water mix and that allowed it to just slide right on. The idea came from the IDS instructions to lube the isolators when installing into bowl. BTW, the thread lock on the OEM bolts was blue, the new bolts had yellow compound.
Managed a 1 hour ride today, it wasn’t bad at 1*C or about 34*F. The IDS works as claimed; it refines the drive train. It is quieter and smoother overall, especially at slow speed, parking lot stuff. This and the SE comp sprocket work well together for me on the ’07.
While there is still some ‘can of marbles’ noise, actually more like a card in the spokes of a bicycle, may even sound a bit like tappets, it is now subdued, refined. It was bothersome, to me, starting at 2500 RPM, regardless of gear. The noise would be subdued (gone) under load, accelerating particularly uphill, or after shifting. It had become my shift indicator at 2700 RPM! It is quieter now; has taken the edge off and can now cruise around 3000 RPM when desired without annoyance. I’m quite happy with the upgrade, especially at the Zanotti price point.
While I had hoped the ‘tappet’ noise would be gone, perhaps there is some actual tappet noise. But wouldn’t you always hear that, even at idle?
BTW, NewHD74Fan, even the ’97 Valkyrie, Goldwing flat 6 motor, shaft drive has an integrated IDS.
Thank you all for the info on HDTimeline that enabled me to do this project and save some considerable $.
