Tuning:

If you find that the engine revs up when hot, then you've set the LSN too rich before you went out for your qualifier. I experienced this also thinking I was looking after the engine and it doesn't like it at all. Lean the LSN a little and rich the HSN a little until you find the balance. Current sleeve material in this OS engine works really well at operating temp but is very tight when cold.

IFMAR/EFRA Legal?:




The crank is legal in it's bore size and the turbo cut does not contact the centre bore so it makes it legal for both IFMAR and EFRA sanctioned events.

I have been running this motor for almost 8 litres (2 gallons) and it is still tight when cold and the conrod is not showing much wear at all. I am super surprised with the performance and now the longevity.

Cheers,

Mike.
