I installed a Polini 81cc kit on my General 5 star w/ a Minarelli V1 last weekend. It went together w/ no problems but has a "ticking" noise when running. Its not the piston hitting the head and runs really well, I think i'm doing everything right as far as the break-in. But this noise is driving me nuts...its like a vibration but i cannot find it, or pinpoint exactly where it coming from. Anyways i'm planning on putting some time in this weekend to diagnose and fix it but i figured ,maybe you all had some ideas as to what it may be beforehand. Thanks alot..
