jedan sumnja, dok drugi misli, a do jucer nije znao ni da postoji, dajte skulirajte
kom se da trazit nek trazi testove, sjecam se tih starih testova dok je RR i S bio vrh ponude i dok hand made 70 nije postojao, nesto vecu snagu je imao S od RR-a i ZX-a
evo nabrzaka sa attacka
Here are graphs with two of the most popular sports kits, the Stage6 Sport Pro and the Polini 70cc Sport.
All dyno runs were done with an aircooled Minarelli engine with standard 12mm carb (!) and standard airfilter. Best jet size was between 85 and 93, depending in which exhaust was used. Variator was a polini 2003. The blue curve is from a Polini 70cc Sport, red graph is from a Stage6 Sport PRO. The Polini makes best power between 8000 and 8500 Rpm, Stage6 revs about 1500 to 2000 higher, hence we needed to use lighter weights (some 4g give or take 0.8g, depending on the exhaust) and heavier clutch springs (Polini, green – yellow). Stage6 comes with a variety of base gaskets, we choose one which sets the squish clearance to 0,6mm, which is what we recommend.
The test:
The Handmade S makes a bit more power on the Polini than the ZX, but still its obvious that it was designed for a 50cc standard cylinder, hence the less than impressive output of 6 Bhp.
With the Stage6 it’s a bit different, but still it’s clear that the cylinder would benefit from a higher revving pipe. Power struggles to go up to 8 Bhp at 60 kph, but then breaks down around 75 again.
