Why would it be any slower ?

I was told it was slower due to no power valve different size barrel

Were you told they had different size exhaust restrictors as shown on page 217 of the Rules ?

Flowing track or Stop Start track ?

"different size barrel" than Please Explain ?

Just compare the times of the 2 classes at the same track.

Ok thanks guys do yo know where I can find out on what restrictor to run

Try reading the KA Rule Book. It's all in there!

Thanks Richard it says to run the 26mm restrictor plate for the j max will that still be legal racing it in restricted heavy also do you know if I'll keep up with it ha ha

If you run a junior max engine in restricted heavy you will put in a 26mm restrictor. If you use a senior max engine in restricted heavy you use a 24.5mm restrictor. This variance is to put both motors on a per with each other. Thus they should be equal in performance. Whether you can keep up depends on your own ability.

Thanks Richard legend
