How do you pull the snorkel from the airbox with out ruining it ? I have had the bike a week - rode it about 4 times 50 pilot jet, 162 main jet, grey wire cut, throtle stop trimmed down . it runs good but still is hard to start - when it is Hot. I have to use the Hot start and give it a little trottle to start it. what should I do next ? where should the niddle be ? What about the (ACV) Air Cut Valve ?
