hi again and sorry slinger .. are you sure you checked the exhaust bolts near the cooling fan ? cause i had mine vibrating and rattle just as a broken bearing. check the stand bolts too.
but if you can hear it koncking at idle.. i suggest buying a cranck for bigbores (yes they exist) and a big bore kit of course
also i must say enjoy the new kymco people
this summer i bought a 2t too.. don`t worry the agility didn`t go.
i bought a piaggio zip 2 in very bad shape, fork bent,all the plastics cracked,the engine totaled..i was able to shake the crank axle inside
but now it`s running great,almoust new engine, repaired the craks with the soldering iron, painted etc
huge difference with 2t istn`t it
