What do you guys mainly use to polish the engine components. Just a type of cleaner wax or aluminum polish
To polish I use a tube of popular Aluminium mag wheel polish. I use my little finger for the top of the piston and fold up a rag and shape it for the button Then I flush away any residual abrasive from the polish with the solvent and then spread the oil thinly over all parts.
Methanol to clean down or brake cleaner to get into the bearings etc. Some use kerosene but all solvents should be used sparingly on cranks where the silicon ramping is used. Don't use petrol, I've been told it will swell the silicon.
I also take a little extra time with a toothbrush to clean out the heatsink fins on the outer of the block and head heatsink. The more mass there is the poorer the heat dissipation. I know it sounds over the top and it's not something everyone needs to do, I enjoy it. All said and done, cleaning the castor residues from your bearings I think, is important so by the time I've removed clutches, pistons, sleeves and crank, might as well do it all.
