Popping & Cracking Harley 1996 Heritage ???????

[doggy]

Hey all just got my 1996 Heritage Nostalga freighted from Adelaide to Cairns Nth Qld last week by Fergusens transport.
My problem is I rode the bike in Adelaide & it ran smooth as. Now I have had it delivered to Wayne Lennards here in Cairns to get road worthy & they are saying its running like a pig. Cracking & popping. I got on it yesterday & yes it is doing this & is impossible to ride. The bike is like its starving for fuel.
OR, is it possible that coming from Adelaide to Nth Qld the moisture in the air is affecting the fuel / air ratio ?
Does anyone know this problem or had this problem. I dont want them taking me for a ride & charging some stupid outrageous price if its something simple. Its pissing me off cause they will not look at it now atleast for another week.

Cheers,
Doggy

Nah the humidity shouldn't affect it that much. Who rode it between when you rode it before and this last time? I'd start to suspect them.

Thanks for the reply wrider. I just sorted it out.
Bad spark plugs ( fouled ready for replacement & a bit of crap in carb. Put a fuel treatment thru & new plugs . Purrrrrrrrrrrs like a kitten now.

Ahhhh now that would make sense... Only problem is I've never heard a Harley that purrs... lol Just giving you a hard time of course!

Lol . no worries there mate.
It was probably the wrong decription wasn't it ? Although it sounds alot better now & does pur. On the other hand it sounded like a homeless drunk pissing , farting & coughing. So I am wrapped its now purring !!!!!!
