Hello all I'm new here to the forum and I'm looking to solve an issue I'm having on my '82 XL80S.
I've had this bike since I was 12 so I have a pretty fond attachment to the thing or I may have caught it on fire by now!!!
It wasnt running when I started restoring it a few weeks ago, turned out to be the crank key sheered off....replaced with a homemade one (Honda woodruff on its way) and it fires up first kick 100% of the time, timing correct, new points, new (Chinese carb), cleaned out fuel line and blew out valve, new aftermarket coil and new spark plug, valves set to .002
The issue is that it will NOT rev up, if throttle is held from 1/4 to 1/2 for longer than a few seconds it will backfire out of the carb. It bogs and the idle screw on the carb does nothing for the rpm except it'll die when going too rich.
It does seem to smoke a fair amount but it only has 800 miles on the speedo!! Although I'm sure that muffler is loaded with all manner of crap.
It also have some kind of pcv system. It has a plug on a hose near the bottom of the frame that let out a really nasty looking lump of sludge and oil so I'm starting to suspect maybe it's clogged up somewhere.
So can someone point me towards what may be causing this issue? I must be missing something, also I haven't replaced the condenser yet but I do have a new one. Thanks in advance everyone!
