FMF/Trex top end 68mm stock stroke


Recommended Posts

So these could be bored or need to be sleeved if bore goes?

They start at 68mm where they are now. If you need to go next size all you do is Bore and you're set.

possibly. Im willing to bet if you send them to a competent builder they can extract some good numbers out of it.

As long as the ports aren't all over the place and crazy timings.

It was probably a super expensive top end when it came out. So not many were sold.

I've only seen Google pics if them. Never knew anyone that owned or physically held on.

The valve open in the upper rpms to make more topend.

Close on the low end to make more low end.

Pretty cool shit when you think about it.
