First off, it's my brother's bike and this is par for the course with him. Were supposed to go riding tomorrow and last night he decided to try to get it started. Battery was sitting 'connected' and he had his fuel switch 'on'. He got a new battery but it won't start. It turns over just fine but won't fire. Is his gas bad?? Do we need to drain tank, carb?? He had no kick starter so we can't purge the carb by kicking it over. I'm heading over tonight to help him and I would like a few options. I tried to topic search bit I didn't find anything relavant. Thanks.
