May be a dumb question but 32.1 or a 60.1 like the ktms
I saw 32:1 they recommended but I'll run Motul 800 50:1.
Carefull. Lots of people decided to do thier own thing when it came to oil mixture on ktms. Then the bike did not run well or worse then they blamed the fuel injection.
I wonder who's going come out with a 500 kit first😄

Got one downstairs..
Kawasaki traditionally marked the stroke on the crankcase...
thanks for that. I was wrong 2 different ways- I thought we were looking at the bottom of the cylinder which is where most the 2 strokes I owned (majority Yamaha) show CC. Also, I've only owned 2 Kawis: 1985 KX250 and 2003 KDX220R which I never did any motor repairs on and rode em and parked em. Never paid close enough attention to crankcases to see the markings on the case as I never needed to do any top end work. My Bad.
Kawasaki has been inconsistent in their markings, I could be wrong, it may be the engine number.
I find it interesting the publicity photos are of the right side of the bike, all the public showings have hidden the left side, they maybe trying to advertise the expansion chamber, there are no close up photos of the left side of the motor, only CAD renderings.

L2S : Yup, I've been trying to read that too!
What gives ?
I try 'Enhance, ENHANCE ', like I see in all the Movies, BUT it Does Not Work !
Just like "The Goggles, They Have No Effect !"
I don't know what to believe, anymore .............. 😭
We both need better software
The first 5 letters look like KX327, it may be a identification number, not the stroke.
Probably BRC but 500's are kind of pointless when you get into the big CC's on two strokes. Yamaha said around 170cc is about as big as you go before diminishing returns becomes so high you aren't gaining the horsepower a four stroke does by simply increasing displacement. Look how the 250f's are passing the 2 strokes in horsepower outright they aren't held back by their design and limited to 9-10k rpm they just keep pulling to 13-15k. Same thing with your big 500's yea if they could get anywhere close to 13k rpm they could compete with modern 450's but they cant and are limited to 8k. 125's don't have that issue with equal displacement four strokes because they can still rip to 13k.
Are the Japanese manufacturers ever going to get away from 32:1?
250 2 strokes can rev significantly higher than 9-10k, 15k is common in shifter karts, but to achieve those revs, different ignitions, expansion chambers and porting is required, along with more frequent top end rebuilds.
No, they don't want to be liable for their bikes seizing, but feel free to run whatever oil ration you like.
That's because they are twins so the cylinders remain small. Big bore singles just fall off with what they can deliver on two strokes is my point.
You are thinking of 250 Supercarts, down under we have a 250 National class, which uses single cylinder 2 stokes, 12-15k is common...

The article you listed says they rev to 10k rpm.
Sounds like a crisp, reliable KX500!
Upwards of 10,000 rpm...
12-15k is common.
