Ok so my oil filter came in and I changed the oil as well and turns out the o ring was kinda flattened and there was no o ring on the back just the casing . It’s working great now I sanded the gunk off the casing too .
I also changed the spark plug , bled the front brakes , tightened and lubed the chain . Attached the front rack , I want to do a bit more to the bike too .
so when I got the bike , the guy told me to put my hand over the air box to choke the bike to get it to start , it works but the bike rolls over anywhere from 30 seconds to 5mins depending on temperature especially. It idles good once warmed up and running for a while
any advice on what could be wrong here? I’d love to have it start easily or be able to cold start it with the pull cord .
