Thank you JIANGDU FLYING HORSE GASOLINE ENGINE FACTORY for asking how to improve your engines, I am sure that if you improve your engines you will get more customers as the word will go around that you have the best engines. I will start by adding a few suggestions on making your engines the best and hope that other members on this board will add theirs.
1. Replace spark plugs with good quality NGK or Bosch plugs
2. Replace plug wires and boots with good quality 7mm.
3. Replace all engine mounting studs , head studs and bolts with good quality grade 8 hardened steel studs and bolts that will not strip.
4.Replace head, intake and exhaust gaskets with better quality ones.
5.Better quality castings for the cylinder jugs with nice straight fins and not the bent messy holed ones we,ve been getting.
6.Real fuel lines and better quality petcocks.
7. no leaky gas tanks, and make sure they are super clean on the inside when they leave the factory.
Ok thats enough from me,I know I have not covered everything so please other members can add to this list, and if JIANGDU FLYING HORSE GASOLINE ENGINE FACTORY wants our business maybe they will start on some of these improvments.I know I will buy a better motor if I know its better than some of the crap thats out there.
