Using Loctite/Silicone on the Top End Gaskets

[byron]

... Its got me thinking is it worth stripping the top end, getting a new base gasket and starting again. Just in case the old loctite goo was out of date. Or not fit for the job. Engine is still on the bench, So i suppose it is easier to do it now rather than it failing once it is back in the scooter.

sounds like it would play on your mind if you didn't do it... like you say, easier to do at this moment

Just to stick my oar in......Loctite bottles are porous .....its the lack of air that makes it go off......

i don`t get out much

Loctite 5910 and Threebond 1184 come in metal tubes.

Picked up some loctite 5920 today. Its got me thinking is it worth stripping the top end, getting a new base gasket and starting again. Just in case the old loctite goo was out of date. Or not fit for the job. Engine is still on the bench, So i suppose it is easier to do it now rather than it failing once it is back in the scooter.

The old loctite was in a bottle about 4 inchs high and has like a bellows for squeezing the orange goo out.

Gaz.

Gaz, as you've stated that your squish is between 1.5 -1.8mm, I'd say do it again and look for a squish of no less than 1.2mm. You may need a thinner base gasket or head gasket to get the right squish and only a thin smear of the Loctite. Don't forget, you'll need to re-torque your head again in a few hundred miles, anyway.
