what happened? broke crank!

[hellride96]

at little sahara a couple of weeks ago, didnt notice my bike bogging at times. then iwas taking off from a stop(not hard) and my bike died. it was sat. night and i had a spare bike to ride so i let it sit. got it home, tore it down founf out that my hot rod crank that was trued and welded from vitos had broke at the snout. ????

flywheel would turn but the crank doesnt. woodruff key is ok, didnt shear it.

what happened???? im runnin the 400cc cheetha kit i figured if the crank was going to break it would have broke in the center??? any suggestions on what happend???

Hot Rods cranks are shit?

 

Been hearing alot of bad things about them lately. Mines still in one piece but for how long?

Trash the "CHEETAH" and go with the "CUBS" and 4mil. Problem solved!

i believe that is irrelevant.

 

 

vitos maybe did a hack job weld? i dont wanna believe cause they have been good peoples to me. maybe just a factory lemon from hotrods. that doesnt seem like a wild story where you dropped the clutch at 15000000 rpm with the tires burried in concrete, so i dont really have any other explanation.

Thats the stupid saying of the year! Cylinders have nothing to do with a broken crank.Why would he want to down grade to cubs?

Ya, I read on here that some people are having problems with the Hot Rods cranks not holding up. I also talked to a couple of builder's and they agreed, but that was a while back so they may have solved the problem now. Just to be safe I would check into more before I bought one. I haven't heard of this happening with Wiesco cranks...............Just my .02

Ok.

1. Last I knew Vito's didn't sell hot rods cranks.

2. Cheetahs flow way more than cubs.

3. Hot Rods and Wiseco are the same cranks.

 

My roomate had a vitos crank. Had... It was not a hot rods crank. Supposed to be welded but wasn't. Didn't have hd bearings anywhere. Vito's stuff seems like the junk.

Wiseco makes the Hotrod cranks, I called for repairs they put me through to the wiseco phoneline.l

Most of those cranks should have been gone by now. All cranks are pretty much made by the same people as I understand it. I've had three break for customers all of which had to be repaired. Most of them broke within 3-5 tanks of gas. Vito's will likely repair it for you if you have the receipt. But man that bad batch of cranks was well over 12-months ago. That's a long way out from a point of sale for a warranty.

 

The problem was on the flywheel side, like a 1000 cranks were machined without a fillet on that side that caused a stress point so they snapped. I've had this issue with both stockers and 4 mills.

the reason that donnG said trash the cheetha cylinders and go with the cubs is because he is my older brother and he is just giving me shit about my quad being down right now. he just got his put back together with cubs and a 4mil and its running very strong, so he figures he is running stronger than me. but i do thank you guys for the info, but all i can do now instead of worrying about WHAT happened is just to fix it bigger and better and go on.

My crank broke in the same spot. I rode my 4mm for about a year before it broke. The builder I bought it from stopped buying from Wiseco, said they wouldn't fix the cranks. Luckily he's fixing mine as we speak.
