    19,5mm should still be fine, 21mm can be to big for some stock cilinders, and in anycase its harder to set up and wont give a noticable increase in performance, so up to 19(,5)mm is fine for a stock cilinder, though there are a few stock cilinders from Gilardoni that got restricted so much on the exhaust port that anything with them is a problem, but thats easy to spot if you look into the exhaust port and its just a slot of 10mm high


    Anyway i would get 0.25~0.30mm reeds with that set up, but 0.30mm is really the max.

    think that reed block is ment to enhance throttle response and acceleration, dont know bout the size reeds in it tho , is that what you have now? are the reeds you have in it now bent or worn or are you just after bit more top speed ect?

    Reeds in aftermakted reedcages are 0.25mm if nothings specified.

    If i where you i get a set of Malossi reeds mate, than you get 0.30, 0.35, and 0.40mm, handy if you want to upgrade to a 70cc kit later on.
    http://www.easyparts.nl/showarticles...40_Val.Or.html

    And no thicker reeds dont mean higher top speed mate, it depents on rpm and crankcase presure what thickness you need, thats why you can estimate a bit what you would need.


    Polini 2 pistonring 50mm (76cc) kit is not unreliable, its a ok kit just like with any other other aluminium performance kit make really sure you got the mixture right, run aditional oil trough the feul, and only use premium feuls and oils, and make sure you got the right sparkplug for the kit! i would use a NGK10EGV with that.

    ok

    personally i wudnt go for the polini kit and i dont like the maxi kit either to be honest but i do not have a clue about the maxi kit one.............

    if it was me id get along these lines:

    http://www.easyparts.nl/showarticles..._49.5_mm.html

    http://www.adrenalin-pedstop.co.uk/p...ines-2016.aspx

    http://www.adrenalin-pedstop.co.uk/p..._XPS-3378.aspx

    http://www.adrenalin-pedstop.co.uk/p...ines-2683.aspx

    youv already got the exhaust and carb for the job just remember to re-jet

    p.s that polini crank looks alright

    oh and reeds, with what you have now then 0.25mm?

    with the tuning above set up then 0.35mm

    yerr i think it is this crankshaft but if you do decide to go for the ital kit then theres a number on the item ad which will tell you the product code so you can get hold of it by adrenaline pedstop

    http://www.adrenalin-pedstop.co.uk/p..._etc-3443.aspx

    maybe since you have a polini carb and polini exhaust maybe its worth getting a complete polini set up so it all matches :

    http://www.adrenalin-pedstop.co.uk/p...ines-4915.aspx

    http://www.adrenalin-pedstop.co.uk/p...ines-2683.aspx

    the polini crank seems a bit pricey to me but it was one of your suggestions and the doppler er1 wud be just as good

    and you already have the exhaust and carb for the job
