A question has arisen as to whether the motor shown below is legal for use in racing under IRRA^® rules.

The answer is yes, it is legal.

The double-shaft JK Hawk Retro formerly carried a simpler laser-etched marking on the can but JK is now supplying the double-shaft Hawk Retro motors with the same repeated '7R' marking that was first used on the single-shaft Hawk Retro motor.

Just to be perfectly clear, the JK Hawk Retro motor with '7R 7R 7R 7R 7R" etching and a shaft on just one side is NOT allowed in IRRA^® racing.

I thought the Retro Hawks were going to have an "RH" stamped on them? Doesn't really matter as long as they have the long shafts on both sides to differentiate from the Hawk 7s.

I'm guessing this means he's using the same cans on both motors. So the etching comes out the same that way. Just different arms?

She's real fine, my 409!!!

They do not have the same engraving.

IIRC, newer Hawk 7s are laser engraved 'H7 H7 H7 H7 H7'.

Has anyone found a fast Hawk Retro motor stamped 7R? I'm about 0 for 7 so far.

What's so confusing? The older JK Retro Hawks had no markings on the motor can other than Made in China. The new ones, both the short shaft model and the dual long shaft model, have the engraved marking 7R across the top of the motor can. My question is, since getting my hands on the engraved 7R motors, I haven't found a fast one and was wondering if anyone has had better luck.

When Howie was practicing for the Sano, I spotted a rocket 7R 7R 7R, in one of the cars, he was hot lapping with.

I'm not sure if he raced it.

I have had some that are just fine. We used them in the enduro here too.
