I put a single ring Wiseco "GP" piston in my bike.

It lasted for exactly 1 lap. I won't get within a mile of that pot metal Taiwanese shit ever again. Cast Japanese pistons only.

Don't worry though. some guy who rides a 98 YZ250 in the woods at walking pace, 3 times a year, will be along soon to tell you about how his Wiseco has lasted him since 2005.

I don't know about Wiseco's quality lately (can't say good or bad) but your experience is the risk you run buying anything on eBay from a normal ebay seller. If you want the chance of some support buy from an authorized retailer. You can't expect first class service with a coach ticket.

Exactly what 731 said.

I had seen some race tech springs on eBay for cheaper than race tech sold them for. I called race tech to ask them why and they were up front about the third party policy. I bought springs from race tech rather than eBay just to avoid any issues. Springs are much more simple and less crucial than a crank mechanically speaking, but it's just a lesson you learned the hard way.

I understand your position about not wanting to pay more for the piece of crap that is causing problems. I'm curious to see what would have happened had you bought it from Wiseco or an authorized distributor.

I suppose you could always purchase a crank straight from Wiseco and pull the old switcheroo. But that'll cost you another crank.

1 lap? I'd put money on it being installer error. But feel free to tell me how you are a master mechanic, etc.

What happens is as follows, verbatim.

You send your part back to Wiseco. You do not hear from them for about 3 weeks. After 3-4 weeks have passed, they have a group of engineers look at you part. They try like hell to find failure not in the part, but in everything around it to include the installer.

When they are absolutely certain that the part was defective, they will send you a new part, completely disregarding everything around it that it destroyed. (Cylinders, heads, ect.)

If you're lucky you'll get some gaskets...as long as Wiseco makes them.

Some people have had better experiences, i'm sure. But that's mine and it was only 3 months ago.

I bought a cheap laptop battery on eBay and it lasted about as long as your crankshaft.

The seller claims a 1-year warranty, but they have not responded to my 384 emails and phone messages.

Of course eBay won't do a damn thing. But hey, that's the downside of cheap merchandise- no guarantees.

eBay is bad news for a million different reasons when it comes to critical components. A lot of people/ countries make a living on making counterfeit parts. Unless you get something direct there is no way to know what you are getting.

I've even dealt with companies getting knock-off/ sub-par parts from their own subs. It can get complicated. Mostly with electronics. Hardware is still an issue though at times. At least going thru the front door of the distributor some assistance can be had thru some level of root cause analysis and hopefully some help sorting out a solution.

I'm sad to say my Wiseco crank just went. Lower rod bearing and left crank bearing have play in it. The hour meter says 31 hours on it. So I just got off the phone with Wiseco and had a ten second conversation, which went like this. Told him what had happened, he asked where did I buy it. I got it on ebay. We don't handle third party warranties. End of conversation. So what they are saying is I should have bought it from them directly and paid even more for their garbage product. Yes I'm bashing Wiseco. They suck. I would be more than happy to send in the crank and bearings so that they can take a look for themselves and supply the purchase date. Should have bought oem....

I don't have any experience with Wiseco cranks, but I have rebuilt OEM cranks using ProX connecting rod kits. The box says the parts are made in Japan.
The kit includes a new connecting rod and lower bearing. Some assembly required

I have no affiliation with either company.
