At the moment Iam doing a 172 conversion on a zip which I've nick named the (Frankenzip) because it's made of dead bike parts Any ways ... It's first got a piaggio zip sp mk2 frame and a piaggio zip sp forks which in I converted to run with Vespa hub and brake set up next the engine was from a dead italiajet dragster which wasn't looking to good so first I had it rebuilded with fresh gaskets and pm tuning seals Nd bearings then new crank nowt special just a better quality 125 crank from ped parts then a oko 28mm carb with a bigger reeds and manifold scorpion bike malossi belt and clutch springs also new pulley next a bar con version from a typhoon stage quick action and switches then a rpm /speedo gauge gilera runner front wheel new pads and discs ported malossi 172 air cooled kit for less troubles the only thing I really need is side casing and cooling covers Ive put some photos below
Hi it's not bodged in Its i level and until my engine decides to work it's staying on 50 mount but when it's starting I'll be welding a 125 mount on to it with silent block
