'Exhausting' tuning carbs, to funny

#1 Post by 2Smoke4Life » Mon Oct 02, 2017 9:11 pm

While finishing up this stock '84 of unknown history I just couldn't get it to sync right and run quite right.
Especially when I couldn't get stock RZ carbs or Banshee carbs tuned right.
Then noticed not much exhaust pressure at end of pipe when revved over 3K-ish, on only RH pipe.
WTH? but it was the cylinder I couldn't get right so....
besides also finding out the carb linkage was not allowing correct sync, fixed that and got different exhaust. Pulled old exhaust and baffles.
RH side still filled w/ catalyst, NICE restriction
LH side was already cleaned out.
Amazing how tough that makes tuning,

Wow! Serious restriction in there! Which pipes are those?
