help with my vx problem

[timmy_philson]

Hi guys, i need help on my vx110, the head has been taken out of the engine to change a bent valve and when the engine was put back to the hull and tried to run the engine, it will idle good but when you start revving the engine, the engine hesitates and just die down and wouldnt even reach 5000 rpm. it soulds like fouled plugs but they are brand new plugs installed in the engine. Anyone out there with the same problem?

Pull out your plugs just to make sure. The same thing happened to my friends vx cruiser at about 4000 RPM it would just die. I pulled the plugs for him and they looks horrible.

I tried to check it as well and put new plugs and still the same, even tried the compression test and its all good.

go back and check cam timing marks,they need to be spot on

Chip, if by chance you do lapping in the valves, do you need to recheck the timing on the cams?

bud if someone laped valves they would have had to pull head,therefor cams+ chain would have be played with AND have missed the mark for timeing myself ,if not dead set you'll piss off the efi and will run as you say
just my two cents
