vertex VS weisco
vertex VS weisco
I see alot of people running weisco. Why no love for the vertex?
Whats the diffrences? advantages? disadvantages?

There is always debate over what is better. People who run a properly seasoned and warmed up Wiseco love them. People that have them get stuck in the cylinder hate them. Personally the only advantage of the Wiseco is it's ability to withstand the extremes of running your cr500 on Alky. For any other riding, there is no advantage in running a forged piston.
Don't Clyde it, ride it!

I agree with ported&polished, but I can say the forged does give you alittle more protection if you havn't got your engine tuned exactly where it should be. Cast don't like detanation, where I have had my weisco live with a slight amount, not good on my part, I didnt want too loose the race. LOL
lots of power is never enough

Well, they obviously dont make a garbage product, or they wouldnt have been around so long.

Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.

Personally I wouldn't drill holes in a cast piston, but I never heard of anyone having problems after they did it.
I've never seized a Wiseco, but I wouldn't use one again. Every one that I used in my watercraft shrank about 0.004" after using it about 20 hours. Other members of the watercraft forum had the same problem. They didn't look worn out either.

i think ill try the Vertex... No holes need to be drilled correct? Would it hurt it if i did anyways?

Like has been previously stated, Proper clearances are crucial to the longevity of Wiseco's, but if everything is tits, so long as the proper warm-up is achieved, they will perform as well as anything else out there.
ive got one in my bike, and my motor had at least 100 hours on it when it needed rebuilt, and the rebuild wasnt caused by the piston......lower rod bearing took it out. other than the groove in the piston from the bearing, the rest of the top end was mint, minus a few detonation marks in the piston, which came from running low-grade fuel (NEEDED gas, only station around, all they had :/

what happens when you have tuned it on the dyno in perfect conditions and you take it out on a hot or cold dayr1yfz wrote:ill be doing all of my tuneing on the dyno so it should be dialed in to perfection.

I am always squawking about castor oil, proper jetting, cast pistons, and quality machine work... Why?
I popped my head off to modify it, and this is what I found...after almost 4 years of hammering on it....
PERFECT cylinder. No scrapes, no blowby, no black death, no "stop-sign".. hone makes look identical to the day I assembled it . I could not be happier!!
The studs keep making the camera focus on them, and not the cylinder wall. I'll try to get a better photo, it looks that good!
Exhaust ports are pretty free of carbon, sludge, or other junk that Castor oil gets blamed for.. Soot pattern is very semetricial, showing that the burn is well balanced.
Heres the best focused one of the cylinder, perfect!
Chamber looks great too....
See, paying attendion to details before, during, and after assembly does pay off!
