Malosi reed block tuning

I read that some of you have tried different reed thicknesses on your Malossi reed block. Curious to what you have found.

I have one on my Puch Polini kit and while the low & midrange acceleration is excellent, the top end suffers compared to other carbs and setups I have used.

Taller gearing only makes it worse ( weird I know with all that extra power).

Question: would a thinner (or thicker) reed on one side allow the engine to rev up more and improve top end?

Setup E50 polini, 21mmPHBG, techno estoril pipe. Stock points stator with gap at 13-14 thousandths and 1.3 - 1.5 mm BTC timing settings tried.

17 - 45 gearing seems to max out at 9000 rpm & 44mph.

This kit and pipe have revved out to 10,500 & 50mph before with a 15 bing carb and polini flat reed.

let me know what you have tried!
