Re: #68 Delortto Jet swap
Just swapping the jet made a really big difference in the way the engine ran up top. I think a #65 with a lower clip positoin on the needle and itll run really great. With the #68 my bike runs over 40mph, but still experiences some top end studdering and missing which can be resolved by turning the petcock to the off position(limiting the amount fuel going in). The leads me to believe that while the #68 helps the engine to run better its still getting to much fuel. Though on some days its fine, others it runs crazy. Cheap parts means limited tuning.
Yes though the Dellorto 1486, jets fit rite in the china carbs.
...ive gone to the scooter side, variators arent that bad.
