Stroker Plate - Any Good?

[Arizonaduner]

I need some advice. I need a new crank and I'd like to get a +4mm. I'd also like to keep my stock cyls (Already ported) for now. By using a stroker plate, and two base gaskets, it looks like the port timing will stay close to the same (I feel comfortable altering it a little if needed).

 

My question is, what sort of sealing issues or problems have been encountered with the stroker plates?

 

My alternative, if I don't use the stroker plate, would be large changes to the port timing in the stock cyls which I'd like to avoid if possible.

 

This is what I'm considering:

you just run the plate by itself with no gaskets, just use plenty of like ultra gray or yamabond.

 

you might talk to your builder or guy that ported the cylinders on how it would work, i know sometimes it messing the timing up with raising the cylinders. and if you seal it correctly it wont leak and will work correctly. its just like a gasket just a lot thicker. people say its another place to have an air leak so are base gaskets.

 

anyways.

 

 

your builder might suggest cut domes, who knows its just in how the port timing will be

The ports will be off no matter what. Even though the plate will raise the cylinders to where the top of the piston is flush with the top of the cylinder, when the piston is at BDC there will still be a 4mm gap between the piston top and the bottom of the ports.

 

It will still run, but you won't be gaining that much more power until the motor is ported properly.

Thats what i always thought, you can make up the 2mm up top, but what about the 2mm @bdc ...da your the 1st person that has brought this up (that i've seen)

 

I know there has to be somebody out there that has done it, what were your opinions on the power losses?
