X18 Chain

Ok I Have A Simple Question. Is It Bettr That The Chain On My X18 Bike Goes On Tight Or Loose? Or Jus A Lil Loose? And When I Turn Her On, The "0" On My Dash (meaning I Am In Neutral) Goes Low Because The Wires Are Not Making Full Contact. And She Cuts Off When The "0" Goes Low. Or When The Wires Dont Make Perfect Conttact

The chain needs 1/2-3/4" of slack...Too loose the chain will skip and too tight it will heat-up and stretch...not that the cheapo chains last much longer if adjusted properly all the time........replacing the cheapo chain with a DID 420 standard chain will last alot longer......Peace
