[cabex]

My Z has allitle crackle that happens if I let off the gas. I know that it is running alittle lean. But I was woundering If it would be bad for it to drive it this way?

Thanks

Mine was like that for a year and my engine builder told me i still running it to rich. I wouldnt ride a 2 stroke like that but yours should be ok.
