Default Engine sealant on New Engine

I have a brand new Ninja Jx.21 engine. Im thinking about putting engine sealant ( Lucky 7 ) on it before doing the break-in. What you guys think... Should i put the engine sealant before doing the break-in or after?

Tear it down, flush with fuel to make sure no contaminants are in there, then seal her up

When I seal a motor I usually just do the backplate, both sides of the pinch bolt, and base of the carb.

The great thing about Lucky 7 is you can use it on all points that could cause a leak. Backplate,Pinch bolt, Carb neck, fuel nipple...etc

Default L7 Engine Sealant Instructions

L7 engine sealant is intended for external use only. I recommend installing only 1 mount mount screw and mocking up the carb angle etc, then i pull the engine back out, make sure everything is tight and seal up around the carb base, pinch bolt ends, and HSN assembly. NOW when using the sealant you'll find its very thin and easy to work around (wicking) into the tight areas making a good seal. I'll actually apply an excessive amount in one spot and blow on it to help work into tight areas were i can't get the applicator tip. don't be afraid to apply what may look like to much, cause when it drys it shrinks down to a tight coating. Hope this helps good luck!

So far it sounds like i should put the engine sealant on my new engine before doing the break-in on it. How long should i wait till it dry up?

L7 needs an hour or 2 to cure up pending ambient temp

there are other alternative's but nothing like L7...its Very liquidy and flows nice depending the part you are trying to seal....there are still some who like a silicone type consistency as their preferred sealant....1 product is Racers Edge Carb sealant or the expensive version Three Bond 1211
