Re: Been An Adventure With China.
They're stronger than you think. Ive done over 600kms with the original supplied clear fuel line and apart from it hardening up a bit it still works fine. Ive replaced the studs with high tensile bolts on my build and replaced the head bolts with high tensile units as well. Ive also loctited everything and copper siliconed all the joints on the intake tract. My throttle was also very stiff when I got it but I just lubed it and the cable up with oil and now its fine.
One thing I have learned with these kits it to not over tighten anything!
