Hey, at least yours lasted 31 hours. I've heard some major horror stories. I'm usually that guy that buys all the cheap shit but after reading all the Wiseco is siezeco type sit I was like, nope not this time. I couldn't think about the though of one of my sons loosing a bottom end bearing on the face of a massive jump. I just wasn't going to gamble with their health or ability to walk. I have bought nothing but Hot Rods cranks with the exception of an occasional factory Honda crank for our 125's. Everyone except Honda's OEM cranks are out of my league.

31 hours isn't bad depending on type of use. Hard core, bouncing off the rev limiter type riding should at least have a thorough take down and inspection. I think on my 04 CRF450 Honda recommended piston and rings replacement at 10hours.

I called wiseco before ordering a crank for my 2000 kx 250 and the guy said that the more expensive price of buying direct from wiseco basically bought you a warranty. They wanted more than a hotrods crank cost so I just bought a hot rods. Speaking of pistons though- I bought a namura and ill never install that cheap looking piece of shit. It helps that i only bought it to measure cylinder clearances and paid only $15 for it in a trade.

I also had the ring locator pin fall out of a wiseco. Destroyed the cylinder and power valve on my step sons KX100. He was a very slow rider. It took about 4 hours.

Why anyone would put anything other then OEM is beyond my comprehension. Save now and pay big time later. Makes sense.

Uhh i hope u mean inspect at 10 hrs. And 31 hours is pretty shitty.

That would not happen with a 4 stroke (no locator pin) Whistling

Anyway, I always associated Wiseco with bikes but apparently they make pistons for cars too. One local Subaru enthusiast is rebuilding his engine and was proudly showing pictures of the Wiseco piston he was going to install.

Huh, well my kid isn't a "slow woods rider" and when I bought his YZ105 supermini I bought the rest of the pistons the guy had for it. They were all Wiseco and we have been running them for two years. I pull them at around 20 hours and they still look great................That motor is stupid fast too and smooth to ride. I always tell people I'm pissed at the seller as once I bought that bike he wouldn't ride anything else.......................I wouldn't run a Wiseco crank, however..........The pistons come with a cool little carry bag that makes me laugh. What purpose does that serve?......

Not wiseco and not oem. Had about 30 hours on it. Luckily for me it happened mid air off of a fast table. Trying to save a hundred bucks over oem cost me a cracked tib-fib and torn meniscus. Could have been much worse. Lesson learned the hard way.

Jesus that is what scares me. Locking up on a face of a jump or midair.

On a side note the ebayer I bought it from was OEMCycle.com so I am going to contact them and try to have them send it back to Wiseco.

I can take care of that one, too. The Randy Savage one had been on the watch list for a while. I guess he didn't get the hint when some of his messages were disappearing.

As usual, my tolerance level goes down on repeat customers.

Big companies never want to give credibility to an individual, they have a hard time giving credibility to dealers. If you had gone to your local shop and ordered it, the dealer should have backed you up if it was a true manufacturing defect. Because the dealer is going to buy much more of the product than you ever will they will be more willing to work with the dealer. That being said these vendors try to take care of the people who take care of them. I have used Wiseco pistons in many different applications including pistons and cranks. They have all lasted as long if not longer than the oem pieces that were replaced. Honda cranks are known to explode. Stock and aftermarket! Honda just a bad design on the crank to rod position. Too much of an angle forcing to much pressure on the bearing. I have seen more than a dozen broken rods/ big end bearing failures.. So saving a few hundred on a aftermarket crank that the stock one is already know to have a problem with is just foolish! Stock is trick! You just need to do your general maintenance and not beat the living snot out of your bike...

Sometimes you just have to learn the hard way..

I have spent countless dollars on measuring once and cutting twice..

Looks like you learned two lessons..

1.) Support your local dealer
2.) You get what you pay for

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'm not the guy in the woods, but have a bunch of YZs and use wiseco pistons in them. I typically race 250B and 30+B classes on the YZ125 and sometimes the 450B or Open B on the YZ295.

In my experience with Yamaha two strokes, when the OEM crank fails, it's almost always the big end rod bearing seizing up and melting the plastic crank stuffers. The OEM rods are strong enough that they don't break in this failure mode and the bike just skids to a stop.

I've seen aftermath of several Wiseco crank failures where the bearing seizure also causes the rod to shatter. That broken rod spinning around on the crank destroys the cylinder and the engine cases.

So saving $100 buying that cheap Wiseco crank can cost you over $1000 in cases and top end parts.

On the other hand, I have had excellent results with their regular pistons (not the "GP" version) and use them in my '08 YZ125, '11 YZ125, '10 YZ295, '02 YZ250... The pistons are still made in USA, but I think the cranks come from Tiawan.

I bought a Wiseco crank for my '02 YZ250 back in 2008. I figured it was a US made product like the pistons.
Shortly after that I started seeing more and more trouble with those cranks among other people.
I put over 100 hours on my Wiseco crank with no problems, but having it in that bike worries me.

Wiseco pistons are fantastic. And I'm not a slow woods rider. Those pistons take a lot of abuse.

I've seem new OEM KTM pistons (rebadged Vertexs) shatter on the first day. There was actually a whole batch of them some years back.

I wonder what NHRA Guys do when their rods go through the block in less than 4 seconds?

Who do they call? We have a guy with a 250F race bike turning +/- 13,000 RPMs with 30 hours bitching about a blown crank?

LMAO It sucks, but do you wonder why these dumbasses with Suburus are smoking and knocking with 8K on them?

They arent built turn turn 9 grand all day every day even if thats the redline on the idiot gauge.

I won't use anything other than OEM cranks in any of our bikes anymore, although I've got a Wiseco piston in my CR500. Several years ago my boy's Wiseco crank assembly on a YZ85 snapped the rod about 30 feet in front of the biggest jump on the track. It had less than 20 hours on the crank, but the rod snapping is due to inferior materials, not a bearing failure. My CR500 conversion bike was a 250f that I purchased after the previous owner wadded it up when the Wiseco rod snapped in mid air on a big downhill jump, destroying everything in the engine--I was told that crank had 2 hours on it. But we did have good luck with a Wiseco clutch basket and of course pistons.

Ive ran Wiseco pistons since the beginning of my riding career and never had a problem. Don't have any experience with the cranks though.

Made in Japan and good stuff, same as ProX. Their titanium valves are a nice product too.

Wiseco pistons are all I ever ran in my two strokes and Kawi's. Never a piston related issue, plus they are made in USA. A lot of people do not realize Wisecos usually run a bit more cylinder wall clearence due to the expansion of the FORGED piston. A lot of failures are due to not warming the bike up for proper clearence...A cold engine is a sad engine. Their clutch baskets are the best in the business, how can you beat a lifetime warranty?

Wiseco cranks on the other hand I would not touch with your dick. Cheap Chinese junk, same with Hot Rods.

I've seen sport bike guys get over 60000 miles out of a bike with no issues and they rev way higher than a mx bike. I'm just saying we should expect more from manufacturers . 30 hours is bs.
