Yes. All depends. Some may be using a red putty like material. Or tef tape.
I've been using version 1211 lately, read into it a bit more at one point. Chemical: IE Fuel resistance is a plus. Of course I want the oil to stay in as well.
This last ZRX and EJ rebuild had me going down the rabbit hole for added protection.
In rare occasions gravity fed carb systems can fail on the bike and fill a crankcase with gas.
Had it on hand while rebuilding the EJ a year or so ago now.
No leaking on either.
Nice part is it's thinner and has a longer tack time. Thin, brush it on. Keep it clean and fabam. Nice seal and little blowout extra silicon running thru your AVCS hosing your operation internally.
