Paul,
What epoxy did Powersport use to glue their tubes in? Is the same epoxy
used for plugging the intake passages?
Joe Berki
"Hi Paul,
WE NEVER have used Devcon on a peripheral port sleeve.
We do use Devcon cast iron to fill the side ports, but that's all.
We do use Araldite to seal the threads when we screw in the threaded
sleeve. WE still use an o-ring to seal the intake from the water.
Jim"
Jim builds the p-port differently. He bores the hole in perpendicular
to the trochoid surface and threads the outer wall and the tube or
insert as
he calls it. Then he has a shoulder with an O-ring on the inner wall.
He then screws the tube in. At that point you must connect the tube
to the runner with a rubber hose.
I have recently spent a LOT of time and a LOT of money developing
the JB Weld process. Deviate from this process at your own
risk. Believe me... it is not as easy as it looks. There are
several steps that MUST be done right. One screw up and you
will have to start over. I made a huge error in the beginning
by buying the wrong epoxy. Mark Supinski will verify what I say.
I will be glad to walk you through them again.
I have cooked JB Weld in an oven at 300 degrees F. I KNOW it does
the job.
JB Weld works fine to plug the side ports.

Paul, Have you ever used Lumiweld? do know people that have use it to
repaire alloy cam covers,what do you think about useing it to fix in
alloy tubes for peripheral port ......
