54mm piston question

[The_GDFP]

Any body run this?
54mm High Compression Piston Kit

I emailed seller and posted a Facey question, but haven't heard back. Is it for the T-Rex-type 125 Daytona, or a Lifan-based slug? Different valve angles.

i havent used one yet, but soon will be in a custom engine build for one of my bikes... 54 bore and 49.5 rod.. rev like no tomorrow lol..

the piston itself looks like a hi speed from the pics, might order one this week and let you know

Thanks Sean. I have that T-Rex headed fifty four square TRX ninety, and a modded SE piston that's way too much work come freshen up time. I know Daytona makes a slug for their buck and a quarter version. Hi-Speed wouldn't likely be it, though.

I came across an odd crank, forty nine five with a one oh three rod for seventy eight tall jug. TB fifty seven top end and a BV head should zing, on one of my close-ratio Xtreme bottom ends. Great/demented minds...

hmmm, nice.. ill measure my rod today but it came out of a small block so id say its the shorter..
where did you find the long rod one? and yeah i got 57 kit to use if im not happy with a 54..

if not then ill use a 50mm big block crank. only .5 difference so still sweet.. im trying to keep under 124cc but no less than 114
