Hi lads
I've put Jakkals pipes and a zeel and am having a spate set of barrels I got from neal cleaned up.
The engineering shop asked if I would like to tidy up the ports.
Good idea and plan to try an improvement or 2.
Are SP ports the way to go or anyone got an improvement on that?
Please post here with your findings.

I'll do much better than all that old Sp stuff.

how will you do better lozza?
you need the engine to measure?

More power and better spread of power. No the cylinders/rod length/deck height is all I need

I guess this will all depend on which pipes you have, base model Jackals or SP model Jackals.
