Punched mine out to 41. I think it will depend what model you start with. Mine came off a 1998 CR250. We didn't touch the bell mouth on the inlet and left the air vanes in there.

Some of the ones i saw didn't look like they could take that much off

what is this "pro-flow" you speak of glenn? how big can you take one and what do they run?

It's a mach. runs about $10,00.00 to however much you want to spend. I heard a little bird told me roostey was getting one.Roostey don't forget to check a stock PJ also you might be surprised.I've played with all of them on the flow bench and I was surprised at the results

Its been real long time and that motor was fierce. so needle not sure but stock slide as CR250. slides really don't need to be played with if you have right needle. I had to cut the top of the slide so it would clear the bigger bore. haha
