Ahh a newbie eh, can't they be a pain.
Ask me anything you want about EFI systems on 4 strokes turbo conversions or electronics and I'm sorted. I don't know a thing about whats what on these 2 stroke things.. but I am learning fast...
Right, So I need an airbox or something then. No wonder people don't see a gain if that's what should be there already. I just new that nothing there at all was not right. I've done airflow work on other performance road engines and having inlet trumpets or whatever makes a noticeable difference to power.
Ill put a post in buy and sell and see what I can come up with.
As a little update I found a mech pump from a 200EFI and also managed to get hold of another stator so I've actually had this out for test now. Please consider I'm no racer this power head is on a 150v6 Long shaft mid with alu prop on a 17ft Fletcher. Prop def has to go in the bin, and I'll be asking soon about something more suitable, I need to test fuel pressure and may go to elec pump if needs be as the previous owner had.
