<HTML>hello everyone. in case you didn't read my previous posting regarding the 70 cc speed kit i'll sum it up. i purchased a kit (new cylinder/head,piston,15mm carb, and a biturbo exhaust) for my 92 tomos golden bullet tt lx and upon installation and running the piston and cylinder got grinded and destroyed. i thought maybe i ran the throttle too high prior to being broken in and oiled correctly. well either that or i was told it could be a flesh coating problem by the manufacturer. so after being tired of not having a moped for a week i bought a replacement cylinder/piston and just installed it this weekend. we absolutely made sure it was installed correctly and made sure it was even running a bit oil rich to start with and then ran it at idle speed. then it broke again. same exact spot on the piston is grinded. this time the cylinder was spared with maybe a little repair necessary.
does anyone know if it's just my moped make and model that is incompatible with the speedkit? because we installed the same kit on my friend tom's 00 tomos targa lx and it works fine. maybe the piston drops too far into the ped or something like it wasn't made to be compatible with the kit i don't know.
could this possibly be a manufacturer's error since we installed the same thign the same way on another ped with no error? and if so should that be covered even though there's no warranty?
with all this i've dropped $400 into this kit that is just not working. i'm planning on reinstalling my 49cc and cutting my losses. i'd like to have 70cc but don't think i should purchase another piston if the same thing is going to happen.
so if anyone has any information on this ordeal it would be greatly appreciated.
