hi all whats the easyest way to prep my barrol and head for painting? i did the last one with paint stripper but that was pain stackin would it be ok if i justed cleand it with gunk and spray it ive got pj1. i was thinking of getting it grit blasted if i did whats the best way of protecting the barrol?

washing it with gunk would be fine,then give it a wash with brake cleaner to make sure all the oil is removed them paint.

Blasting is tricky...especially with glass beads.

It only takes a few to ruin an engine.

After blasting, I wash everything with warm, soapy water, dry immediately with compressed air, then paint.

Now...many high temp paints need to be heated quite soon after applying, AND they come off easily when handling before curing.

So whipping the top end right on and starting the bike can be a problem.

I heat parts with a propane torch, apply the paint and heat again.

You can see it cure.

+1 on the blast, wash, dry paint process.

Also, PJ1 paint does not need to be heat cured - it cures to a durable finish overnight.
