wiseco piston question

[FREAKSHOW]

I just baught a 2002 banshee. This is my second one. When I baught it I knew i had to replace the crank seal due to burning transmision fluid smell when it ran , the price was right. So anyway I got the engine apart and notcied that the pistons were aftermarket but once I got them cleaned up I found 1 had a 513MO6400 witch is a wiseco piston std bore. The other piston reads

std

513ps

cd

and there is another number at the top A37b4

I have seen a few stock pistons for a shee and this doesnt look like a stock one.

 

Does anyone know what brand this is? by the looks it appears to be forged but I have been fooled before. I have done a bit of digging on the web and found no answer.

It is almost a spitting image of the wiseco but the numers on it have me leary of putting it back together.

What do you guys think?

 

One more question I have is what do people use to reassemble the stock clutch basket when you grind off the rivets to replace the rubbers. I have a hinson in my other shee and that one bolts together. Do I tap and counter sink the bolts like a hinson? Or I have herd people talk of riveting them. When they say rivet them are they refuring to a 1/4 in pop rivet with a long enough shank? Is that strong enough? Please help I am lost......

 

thank you.

513ps is a wiseco standard bore 513 piston. Both are the same but one just has the old markings. PS is P standard. They used to use p-0 - p-9 etc

THANKS, YOU KNOW YOUR STUFF!!!!!

SO THERE IS NO REASON TO BE CONCERNED?

Nothing to be concerned about.

 

But...

 

While it's torn down this far, why don't you have the cylinders and pistons measured for wear. If it's time or close to being time, freshen it up while it's apart....
