I need to know what spark plug to run in a 50cc Malossi MHR team motor for xc and mx mix. Thanks.

Also if anyone knows what thread pattern the hole is in a malossi head that you plug off is that would be great.

That's a common ran plug.
The temp gauge hole can be pluged by a brass plug from an automotive store. Not sure on size tho.

Check your clearance so plug electrode does not get smashed
But tuat is the right plug mentioned above
We run it as the iridium but if on a budget a regular should be fine

We have 20 thousands of squish. So will that be enough space. Also what benifit is there in using iridium over standard plugs.

You will have to check the fitment
Put plug in while piston is down from TDC
Gently roll it over and c if it clears
If not space it using spare plug crush washers or plug indexing spacers

Iridium plugs are easier on to spark so the ign system is under less stress.
