Question about Nova Mega (not Mega) SX15 EVO4 3 ports MS
Just got a fairly new Nova Mega 15 engine (used by barely broken in) for my Impact 02, but I have one question for those who had experience on this engine, the engine is very new in condition, it is non turbo 3 ports, EVO4 MS version but with NO SHIM underneath the head button....not even a 0.1mm, it has none.
For those who still remember this engine, does this engine came WITHOUT any shim, like no shim required? I know my previous owned EVO 4 7 port Turbo engine does came with a silver 0.3mm head shim, however, this one, has NON....
I have tried Serpent website and Nova Mega site, but they did not listed there are shims or no shims for this specific model.........I can recall my evo4 7 ports does has a 0.3mm silver head shim. I have never deal with an engine required NO SHIM at all.....so I am kinda suspicious on this matters.
Not sure that is because this one is the EVO 4 non turbo version.......for those who can still dig out some old spec, please give me a hand....or for those who know engines well, just simple tell me I should add a 0.2mm or 0.3mm shim to start.
I am running 30% fuel. thanks everyone.....
