Motorrad:
Since everyone is chiming in..

and to answer your question. No... a stock port time K5 will not sound Pingy or crisp like a 250. now. to say. crisp is a bad description, because the jetting shouldnt be Mushy, or rich. but it wont have that 250 sound.

As far as helping you out with that airstriker. I dont even know where to start with one of those... never set one up for a K5, or knwn anyone that has...

But the Big K5 is very picky about needles, and Slide cutaways. even with its OWN stock carb.. (pwk) have a slide cutaway that is one step off, and they run like POOP... same with the needle.

Thank you for all that answered. I think I am right there. I looked into it and I am on a 168 main, the JD red top needle in the middle position, and I have a 58 pilot. My fuel screw is 1.5 turns out. I took off the plug after some shredding of the yard and it looks right. Slightly tan, not wet and no dark spots. It idles nice and makes the power. I was just expecting the 250 chrisp-ness, but I guess these aren't that way.

I have this in a 2001 RM250 steel frame chassis and I am using a CR500 DEP pipe. The pipe might throw things off a bit. I have a Wiseco in it, and Eric Gorr ported and epoxy pored my ports. It seems nice and smooth. I guess I have to check it out some more after a day of riding.

Thank you.

Although mine was an ex factory race bike, I think it's very close to stock. Here is the start up right after I put the thinner head gasket after the compression release mod. Apologize for the shabby footage, shot from my phone. Still had some old gas, so I'm surprised it fired up and sounded well right off the bat with 91 pump gas.

Start up.

And running for a bit.
