Okay so I'm new here, I got a 2004 trx90 kinda basket case. It was running, now no spark. So it's pull start only, has no battery or anything. Key switch is rigged up poorly, I need to know how to bypass key switch that only has a green and a black wire, plus maybe test or bypass kill switch, and neutral safety switch. I wanna try these before replacing stuff like cdi and coil, etc. Def has no spark. Please help someone, my son wants to ride badly and I'm trying to look like the hero lol 😂
