Athena head gasket

[martyngsxr1]

In 2 minds about using a Athena top end gasket set is the head gasket going to leak as soon as I run the bike like other aftermarket gaskets

For What Bike? IF for a valvie and it's of 3 metal leaves construction, there is little if any difference to an OEM one.
No experiences with the one piece Aftermarket LC ones though

Mornin,
I have Athena Base gaskets and head gasket on my 4L0, no probs so far.

I had to trim the base gaskets as they were overlapping, I found this out when I checked my squish band.

Iv had various LC,s over the years, but never checked the squish band on any of them until I rebuilt my current engine.

If you are in any way concerned or bothered about checking your squish band, the choice of OEM or pattern head gasket plays a big part, as a genuine head gasket is 2.0 mm thick and an Athena one is 1.2 mm thick, Im not sure how thick other pattern ones are?

I read that most mass produced 2 strokes leave the factory with the squish band set rather wide, due the problems encountered acheiving tollerances on mass produced parts, and again from what I read, LC,s were no different.

Therefore, a standard LC engine, with an Athena head gasket will have a squish band closer to what it should be than the same engine fitted with a genuine Yamaha head gasket, so ....on a standard LC at least....the ones with Athena head gaskets are the fastest !

Checking the squish band is very easy, and I wont be building any more without checking the squish band.
