It was all stock when i got it. Ive put 200x front suspension,3 inch 3 bolt hub extensions and rebuilt the engine. Painted it up a bit but dont have pics yet because im in the process. Im waiting on new hot rod and bearings. But this is where im at.

Not sure on the jetting.I just bought a 34mm Carb off eBay.I simply put it on and it was fine.your ring end gap will be in your manual.
