Hi all! My brother and I are new radical sr3 owners in Southern California (Pasadena area). We both grew up racing karts, Supermoto, and dirt bikes. A few years back I bought an ariel atom, and got ho...

@clark-darrah everybody who saw this initial pics had the same reaction, especially for big americans. It was already re changed and raised from those promo shots. Attached is a screenshot from radica...

@meatman I agree with Dan. If the engine has no seal, all bets are off on what makes up this engine. Regardless of OEM case stamping (which would have been removed & changed at RPE) it is clearly ...

Josh, you mentioned that your engine is 1340cc K8 but that looks like a Gen 1 engine to me, although I would need to see more photos to be sure. There is a chance that it could be a Gen 1 engine with ...

@cirrusdriver and @davidf have you checked the configuration in Race Studio? I had to get a GS-Dash for my car so I could see gearing, shift lights, etc. When I called Aim US, they were not much hel...

I finally got it to work but not sure that I really figured it out. What I did was; uninstalled the Life software from my laptop and installed the Life software from the Radical website (I was previo...

Hi Frank, I think float needles & seats are a good starting point. Debris and or worn parts can cause intermittent flooding of unmetered fuel. I have seen sets bench test fine and not seal consist...
