12,000 rpm that a good one. you could change the bore ,stroke and rod ratio and get those numbers though. Just might be a little slower for the weight of the machine. Would reve like a _ _ bad mother. Factory you could threaten them with a budy and some spike strips that may at least get them to look twice and slow them up a touch but not for long. Last time I rod with them it help me as one goughed out his tire. It was so dusty they could not see my friend lurking in the trees. They did get even when I gernaded mine I guess pay backs a bit _ _.
As far a power block goes I can run mid8's all day long. It takes a little engine work but can be done. A little over rev never hurt either. I just dialed in a new set up and spin it in the mid eights there more to it but touch on it later. I found the best setting is what you engine math tells one they can run and then push it a touch further.
Here a pic of the vapor on a 600' pull with a rev delete I just did on a cdi to test it. It was using a power block with 12 disc. Ill try to get some video to share with an explaination of what I did. As you can see from the engine temp the jetting was a touch rich. The rpm and mph goes up when the temp get close to 190. Upon a sustained run longer in footage it would have easly hit mid 60's like a flat out dune crossing etc.
This is why the post interest me as it may provide a better setting than a power block can delivier .
