Quite a difference in port size.

I’m waiting on some jets so I haven’t really been able to push it but it’s obviously faster.

The size of the stage 6 ports stand out .
That should have plenty more Torque .
Whats the squish that you set that cylinder up with ?
I have a used Trophy cylinder on my shelf its ports are similar in size to the Malossi Sport the trophys port timings are just a notch faster .
I prefer the o-ring heads so I never ran the trophy on any of my scoots.

I didn’t even set it. Just bolted it on. The trophy ran good. I actually had it on a Zuma I had about 10 years ago so when I this I went back with it. O ring head is definitely better but I never had an issue. Probably should have tried something different this go round but it worked out. The trophy is running strong on the vino now.

I know the Trophy always got good reviews and was a go to kit on Zuma Forums ,The scoot I got the Trophy off had plenty of power ,
The Stage 6 Sport Pro comes with multiple gaskets sizes to set squish .
If you want to dial in your street race tighter you could grab the athena/stage 6 gasket set .

Sold my Zuma yesterday. Robbed the multivar & put it on my vino. Also still have the Zuma 125. It just fits me & does everything a little better than the 50 did. It was fun to play with but when it came down to it I just wasn’t riding it. I still love 2 strokes but don’t sleep on a 158 on a 125, they run good.
