The pods do not run well on two strokes.
How do you mean? With the rejet my bike starts first kick and seems to run fine up until about 70mph. Then acceleration just becomes very slow. I've been told that with the pods I need to go richer which I did but I think not eno0ugh.
Do a plug read. Run the bike thru about 4 gears at top revs. Pull the clutch in and hit kill switch at same time and coast to a stop clutch in. Take plugs out and look at color. Should be a tan color.
I have not done a plug read yet but I feel pretty good about how it's running so far. I don't ride it real hard so if it's still a little lean I don't think I'll have any problems.
Have you adjusted oil pump correctly?
I have not adjusted the oil pump. It smokes faintly at idle and hardly at all once moving. No problem with plugs fouling.
The newer two stroke injection oil is much better and can run at a lower ratio. You running NGK B8 plugs and what do you have the gap at.
Yes B8 plugs. I forget the gap but it's what the manual calls out.
Those bike are really comfy at highway speeds. Beware those solid foot pegs can be brutal in an accident. Have you cleaned and repacked the silencers?
I cleaned the silencers (with fiyah, lol) I did not repack because it was too quiet. It's a little louder now but in no way obnoxious. The lack of packing has probably contributed to the slightly lean condition, no doubt.

Two stroke depend on a good vacuum to pull fuel out of the float bowls and less restrictive filters can have an effect on this. I use to gap plug a little wider than .024 that I remember specified. The pipes should have silencer material installed because it will change the way the pipe works. Whatever you do lean is a bad thing. Fuel helps cool the engine and a two stroke operates at a slim area between great and catastrophe. The GT does inject oil into the cranks if memory serves me right. I have no idea who does three cylinder crank balancing and rebuilding. Jemco does build a good pipe that works. Get them raw and Jet Hot Coating works great

OMG, I had a gold GT550 and a blue GT380 in college. Both ran. GT550 puked it's center cylinder on a clogged jet (too lean). Dropped the 380 motor in the nicer 550 frame and rode it a bit more. Bikes were given away at some point for $50 or so. And now folks are driving to Florida to relive the "magic". Run away run away run away!!

J/K. Have fun with the old beasts.
