For reference here is a better picture of what the valve cover looks like on a K8 engine. The K7 engines don't have that plate covering the spark plugs. Attachment : IMG_0098.JPG

Hi @gordon513, Welcome to the Forum!! Congratulations on getting a car with such a rich a history.

Today I got an email from one of my Registry friends letting me know that a scammer responded to his "Item wanted" add in the "Parts for Sale" section. Someone texted him from a Louisiana number offe...

Hi @benoitm, Welcome to the Forum! I am looking forward to hearing about your car. What chassis number is it?

@meatman the easiest way to tell the k7 from the k8 is to look at the valve cover. The k8’s have a plate over the top of the plug wires that has to be removed to take out the spark plugs and the k7 d...

Wow, at least you know where your problems are. My guess is that something large got stuck in the GDU gear which caused the gear to break which in turn caused the other issues. How many hours are o...

Hi @smoothcriminal, welcome to the Forum! It looks like you had a fun first day on the track. There re plenty of people here that are happy to help if you have any questions. 🙂

@rojid, tell your friend to step in the brake harder. My wife can generate enough force so he should be able to do it also. When I am solo at the track I usually ask someone at the track if they wou...

@rojid, I use a long 3/4” drive torque wrench (Proto 6020 a/b) to torque the wheels. I have a person get in the car and step firmly on the brake and then I torque the wheel. To remove the wheel I us...

Hi Clark (@clark-darrah), I don’t have any first hand experience with the SR 10 but I can tell you that with the 1500 in my SR3 I always had an oil analysis done at every oil change and the results al...

interesting engine can you elaborate on some of the details on the engine. Is it a k7 or k8 based engine? Was this originally a Radical engine or is it a standard Hayabusa? Do you know what the boa...
