    I assume the gobbler is the bottom valve. Curious how the external adjuster for the design will work on the 790R forks. What more would you have to do to my forks beyond what you did last winter?

    Thank you Steve. Just finished drawing up the preliminary design and sent it off to one of the engineers I am working with. It will be a bit, but the 790R Gobblers are going to be a big deal.

    Another very happy customer here chiming in re @Torque's work. The 790 R was transformed thanks to his re-design, night and day.

    That is very impressive. I bet the stock rear shock on my bike would have thrown the rider over the bars, on that last log hit.

    Soften that rebound.

    Not a 790, but this is what the Gobbers look like in both a 640A and a 950A. Both bike’s suspensions have also been reworked by Suspension 101 as well. So for all of you 790 owners out here, it will be worth the wait.

    The weather here isn’t being cooperative to allow much testing, but I did get the progressive rate shorter spring installed the other day. This spring, purchased through Torque, is dimensioned to lower the bike by about 1.25”. I made and installed a 0.44”nylon spacer in the shock.

    The spring tool turned out being a bit overkill, but was made mostly of scraps I had laying around. The thrust bearing was an ebay purchase.

    Interesting lowering kit. Let us know how it does? I've thought about lowering the bike an inch or so bit more control in off camber situations, stops.

    Nice job on the shortening spacer. I see you allow for fluid to flow.

    Thanks! I’m sure a larger bore all the way through would have been just fine too. I rode the bike a little on Wednesday. The temps have been such that frost stays on the county road here, where in the shade. I could feel the bike sliding a bit but rather enjoyed that. Yesterday someone concerned about the slippery road must have complained. Now there’s sand (& salt I fear) all over the place. This seems to happen every year around this time.

    The new fork springs’ ID is about 0.022” smaller than the OD of the black plastic ring on the fork cap ass’y. Does the plastic ring just pop off the cap assembly? It will spin on there. There must be a small lip it’s stretched over. CBCB3601-E752-443A-9295-769E5E3BC360.jpeg I pried on it a little bit but didn’t get too rough with it yet. I assume I just need to turn the OD of the plastic ring to clear the spring? Maybe a heat gun would help that ring to soften/expand a little, to make removal easier.

    I just popped those rings off. No issues that I have found.

    Thanks. Yes, I warmed it with a heat gun and it came off easily.

    Just get a little medieval on them and get them off. Then I rigged up mine with a bolt and washers etc to mount them in a battery drill so they can be spun up against a linisher or belt sander to bring the OD down to get clearance on spring. Another thing I did was put an internal chamfer on the top of spring where it seats up on the preload adjuster as in one position or another it hits the angled portion of it.

    I put the whole cap in the lathe with the plastic secured and put them on a diet.

    I had a piece of nylon bar stock chucked in the lathe to make spacers from, so turned a dia of .940” on that , pressed the ring on & gave it a trim.

    Nice work on the lowering setup. I have gone the other way, going to 270mm travel with the magic supplied by @Torque, although I added my own version of a remote reservoir to keep things cool with the under-sized shock.
