Ok picked up a DLH vario kit for the 139QMB on ebay. $20 so WTF let's try it. Top speed biatch!!! DLH is not only a sharp dresser but tops in the world of motorcycle. Says so right on the kit. DUH!  Anyway it's got this washer/shim in it. Where's it go? Or not go?   |

The washer is a shim for your drive boss. It will keep your belt from reaching the top of the drive face.
Where does it go?
Trash can.

I disagree on the trash can.
Keep it as a tuning tool. Sometimes it helps the belt ride low in the front pulley. Depends on the exact setup. If you find that your belt can't ride in the center of the front pulley because there is not enough clearance, you can try adding the spacer to improve the situation. Sometimes it has no effect on top end, so it's only a gain. Sometimes it does indeed negatively impact top speed. Test passes will tell you what it does in your individual case. You can mark the variator as an additional data point. Measure it after a run with the washer. Mark it again. Measure after a run without the washer. Combined with speed, RPM, and observations from the runs, you can make an educated decision on if it helps or hurts or if you like it or not. IMO CVT work does come down to personal preference to some degree.
Sometimes if you get one dialed in with a new belt and use the spacer, you can take the spacer out later when the belt wears a bit and get the same results you had with a new belt. That's not to say you should take it to extremes and then grind down a drive boss to avoid belt replacement eventually. At some point the belt is at a much greater risk of failure. 0.5-1.0mm shims being removed often works well though for the first stages of wear. Most service limits are 1-2mm below original spec and should be regarded as proper replacement protocol.

I've got the same kit in my scooter but can't remember if I actually used the shim washer or not since I installed it last year.. It seems to run pretty good. I ended up with 8 gram sliders, but am about to upgrade the clutch to a performance clutch. I think mine is pretty much worn out.

Dlh... Well would suggest naraku variator or Dr pulley variator... Dlh lasted a whopping 200 miles (destroyed Dr pulley sliders as well as guides in the process)...
So imo the little extra $$ is worth it in the long run...
Just my 2cents...

I have been using the Koso (which appears to be made by the same folks) and was very happy with the constant 8,000 rpm from launch, to top end using 5 gram sliders. My inner bushing failed so I replaced it with an oilite bushing...and that failed. I put on a stock variator and, using the same 5 gram sliders, the rpm level sucks! So, I ordered a kit like the one you have and it just arrived today. There is no washer in my kit, just the 9 rollers, clutch springs, etc. I just wanted the same kind of variator performance I had with the Koso.
Hopefully I will install it tomorrow and see how this one does. I also ordered and received 4.5 gram sliders so I can mix and match them with my 5 gram sliders in case I need to go back to my stock variator.
