Thank you Rod, interesting that your XX is heavier. Have you weighed your XX? Wondering how close it might be to my car's weight. I am going to consider pulling the Halo bars and putting the non-ha...

Thanks Charley. Yes, I meant for a certified Radical workshop to do this work (there's only one in NZ I believe), was more curious about the extent of modifications required for a 1340 to decide wheth...

Hi Dave (@def1), I wouldn't recommend using a stock Hayabusa motor cycle engine in a Radical. Radical makes a lot of changes withing the engine that enable it to survive in an automotive environment...

@roadracer28 oh dear that sounds horrid and far worse than my experience where all i had to do was replace the solenoid. It sounds like you've done all the sensible things anyone could do (i'm definit...

The rumors of my demise have great been exagerated! 🤣 It sounds like the input board might be damaged. The PDM would have to go back to AiM to get checked out. If you're in the US, it can ...

Hello, I have a SR3 XX delivered new in Dec 2023. I have been club racing it and am consistently 100lbs over the min weight, I am 200 lbs. I finally got a set of scales and weigh it with all fuel pu...

@davidf thanks for all the input, super helpful. I got the job done in the end. I used a single sling strap. I can see why you used a 2nd strap going diagonal. I came across a number of issues durin...

I think I have done it both ways, and I don't think it is critical, but use your best judgement on what you think is safe and secure. Here are a couple of pictures: Attachment : engine 2.jpg ...

@davidf i'm up to step 18...the big day is tomorrow morning. A couple of things i'm not sure about, - it sounds like I only need to hang the engine off 2 bolts (green) where the top mounts attach eit...

Jenvey wanted me to change the design of the DBW -- they didn't like how I'd made the actuator driver the throttle directly, rather than through a linkage. I'm a big believer in learning from experts,...

While I wait for some final parts on the DBW actuator, I've turned my attention to the PWM control of the fuel pump. The OEM design is to use a return line with a mechanical regulator, and while it's ...

The sensor calibrations have all been done -- that's just a matter of patience and mastering the M1 Tune software to enter them all. The MoTeC is like a late model manufacturer ECU -- there are no fu...

My trial ignition coil arrived today. It's from the Bosch Motorsports catalog, designated PS-T. Truth be told, it's a passenger car coil used in Alfa Romeos in the early 2000s. Most importantly: it fi...

With the vacuum manifold and vacuum port problem solved, I've moved on to how the actuator will work. I found a sweet 8mm ID CNC router coupler that allows the actuator to directly drive the throttle ...

Last night's project was the vacuum manifold. Each of the just created throttle body vacuum ports will be connected to the manifold. There are two additional ports: one goes to the MAP sensor (the who...
