Progressive fork springs, oil weight and tapered bearings

What oil weight are you running/is recommended with progressive fork springs? I have a 2000 Shadow VT1100C

Also, for changing head bearings to tapered ones, what tools did you use to get the old races out/new races in? I have done this before with just a hammer and punch but that is not always easy depending on the bike.

I use Mobil1 synthetic ATF for fork oil. Works fine in a VFR800, VLX and 2 ST1100s. Seals last almost indefinitely. I don't have any tools that are specifically for head bearings.

I used 12.5 wt oil. I will be changing back to a 10wt next to try and soften things a touch. I think 7wt trans fluid might be to light for me. I just need a touch softer for in town. On the road I am fine how it is now. I found cuttong the spacer to what they reccomen is better than using the factory spacer for me. I just did that. I really like the springs though.

I was very pleased with the stock oil. Honda SS8 shares the same viscosity rating as Belray 10w. FWIW I rode two up about 80% of my mileage. Going back to Progressives on the Valk this winter. Not pleased with the Racetech single rate springs for the overall ride.

I went with heavier oil than recommended after swapping in Progressive springs. I still find the front end a bit soft.

@sidejam , did you cut the spacer tubes down that they gave you? If so, using the stock tubes will stiffen it a touch more. At least it did on my bike.

I can't recall exactly... but, I'm pretty sure we had to cut the tubes down. I remember my mechanic calling Progressive to make sure they were cut to the correct length.

Today, I dialled up the settings on the rear shocks. Front and rear seem to be working well together now. If I decide to hang on to the bike, I'll likely pull the Progressive springs out and replace them with RaceTech springs and Gold Valve Emulators.

For some odd reason I had go purchase more tube as they sent me too short in length pieces to get the 1/2" preload.
