I'm still recovering from a long 4 day race weekend, actually had to take a day off work today to rest a pinched nerve in my back from spending too much time hunched over while wrenching on my cars... rookie mistake I won't make again!
So last Thursday Ryan Lutz, Joe Bornhorst and Matt Wolter hosted a "Racing Clinic" at our local club. Although the clinic was primarily geared for 1/8 racing, I had brought in my EB410 for the guys to look over and see what kind of feedback they had to offer on my setup for our local turf track. After a few minor tweaks here and there, the car was pretty dialed and after Ryan watched me drive a few laps to study the line, he took over the controls and quickly adjusted to my radio setup and I took some video to share with you guys:
Here is the current setup with the car in the video:
EB410 Setup - Bill DeLong - Thornhill Jr - Turf
Joe spent some time with me on the shocks and here are my notes:
My shocks were significantly smoother after using Joe's method to rebuild them... no more pumping 20 times... the method explained in the manual tends to expel more fluid than is necessary and you can end up with too much air in the shock leaving inconsistent results
Anyway, it was pretty cool to get to hang out with most of the Tekno pros this weekend, extra special thanks to Matt Wolter for a front ET48 shock shaft that I bent after hitting an un-marshaled car on the front straight during open practice... my race weekend was almost over because the on site shop had already sold out of the part I needed and Matt saved my bacon. This would eventually lead up to a clean sweep from Tekno on the podium for Sportsman eTruck

Joe spent some time with me on the shocks and here are my notes:
- Shock caps should screw on easily with fingers all the way down, if you have to use pliers then they are cross threaded. You need to press the cap down firmly and twist counter clockwise until you feel a pop, then begin to twist clockwise to tighten
- Droop is measured from plastic to plastic of the exposed shock shaft, you need to back out the threads on the ball end to make droop. Measure the exposed threads and cover the threads with rubber o-rings to prevent excessive travel back up into the shock chamber.
- Fill shock half way, then pump a few times to free any trapped air from under the piston, then extend to full droop and completely fill the shock to the top. Remove bleeder screw before tightening shock cap. Once cap is secure, slowly (I mean VERY slowly) work the piston up to no droop. You should see air bubbles vent through the bleeder hole and you want to minimize the amount of fluid that comes out of the bleeder hole which is why you need to work the piston very slow. Once you get to no droop then fasten the bleeder screw and pump the shock a few times, confirm no hydro-locking and that's all there is to it

But got mines coming. I changed oils in the rear shocks yesterday and one of the bleeder holes is stripped.

Man, After your post earlier I went and put them on my cart. I stepped away for a few (im at work) then I read the were out. No I saw your post again and just pulled the trigger. Got a big race next week and due to thanksgiving weekend shipping might be slower. Got to keep that in mind.

Yeah man as much as I love this buggy those stock caps were a tough one to take lol. I am lucky that my next rebuild will be using these aluminum caps rather than having to work with stripped bleeder holes like I've seen over on the FB page. The order I placed this morning already has a tracking number

The optional spurs are not out yet, so you're probably going to want to start in the ranged of a 29-32t unless you are running Tekin's new RPM motor. For that motor people are running around 26t for pinion.

Here's a little tip for getting those shock caps to go on a lot easier on new builds. Take your caps and give them a few light squeezes in the 17mm part of your Tekno multi tool, rotate it a few times with a light squeeze each time, it makes them round and they go right on. Hope this helps!
I've updated the wiki to include this tip, thanks!
