Posted by: @bill-snead Hello- Anyone have a recommendation on a good brand of tie down ratchet straps? So many out there. I will be using the hub tie down locations. Thanks! Hard to go wrong with Ma...

well thought i'd update this as i finally got round to wiring up the camera.. turned out pretty good. I'm still debating whether to stick it at the rear of the car and wire it back up, but that'll re...

Posted by: @parsonsj Call Spring Mountain, and they'll send you the freight box via UPS. You'll have to figure out how to put it together, but it's a simple job. Removing the engine, draining all flu...

@meatman - I can only help let you know what I did with mine, that looked similar to yours. I ended up machining the faces of the nuts in a lathe. We made a threaded jig (left hand thread on one end,...

@davidf Glad you got it fixed and I'll echo your comments about the WISKO techs. When I first got my car it wouldn't shift out of neutral after the first day. They worked really late to figure out i...

With the help from some friends at Radical I just updated the latest Revision to the "Identifying Radical Model Years By Chassis Number" Guide. The latest version shows the start of the 2022 model ye...

The only Parts List and Exploded view I have been able to find for the Radical SR3 Gear Drive Unit (GDU) has such small writing that it is extremely difficult to read... So I modified it so it is now ...

Swapping the throttle bodies did not help isolate the problem. I swapped throttle bodies on both cars. The problem car had the same problem -- fires and dies 1 to 2 seconds later. The good car runs...

@davidf - I installed a brand new engine from Radical late last year as well... and had EXACTLY this issue. After many, many attempts to increase idle speed and modulate the throttle to try and get t...
