As thin as possible. 0.25mm should be fine.

What Lucass said...Thinner is better. Looks like carbon fiber? The stock reeds are stainless steel, last forever, but usually do not have a "performance" bend as they open, I don't believe. (For some race bikes can have a taper) My engine came with the same reeds as the Dio. The thinner carbon ones, (I now have Polini's) will not have as much of a linear taper as they open...IMO, smoother response and better closing seal than the steel ones.
(I also modified my reed block to match the case port)

hi Lucass2T, what do you think if i use this on my stock carb? I dunno if those will work with your reed cage. I think malossi makes a set for the dio aka peugeot speedfight or if you have the old style reed cage go with peugeot rapido petals. |

That is not 100% accurate. It depends at what rpms you want to run with. I did an extensive search on reed petal info and the opinions could not be more different. From what I understand is thin petals give you better response at lower rpms or let's say from take off to mid-throttle. Thick petals give you better performance at high(er) rpms but give a bit slower response at lower rpms. So if you have a sport grade or stock scooter then thinner petals might be better if you have a mid-race or race setup then thick petals are better. Most heavier tuned scooters skip the low rpms and engage at 6500- upwards rpms. Maybe a good compromise would be 0.3 or 0.35 petals? I personally use 0.45 glass fiber reed petals on both my scooters (sport and mid-race setups), no issues thus far. |

That is quite correct tsimi! We used to try and match the reed to the power band on race bikes...actually anything, as you stated. I found it quite a trying experience in the old days with less material choice. My old Yamaha 125 twin had a pipe that came on at just under 9000 rpm, but came on hard! (top rpm was 13,500)
Being an old man, I simply try to expand the low-to-mid range power, where I use it most. Not always successful first try, but it is fun to play.
