Time to eat a little crow

crank

Yep I was just a we kid when I seen one of those Evil looking sleds on my Trail Cat 340. Stopped by the local Yamaha shop and they were cutting the cranks off and running bolts through the pto ends then sending them off to get crushed. To bad since there 1982 500 would of ate everything up that year. Then they bring out the Vmax 540 that needed even more massaging to be competitive. Ah the good old days NOT!!!!!!!!!

Purchase the Second Year

The driveshaft issue and perhaps possible issues with the belt drive has prevented me from considering selling my 2012 pro Rmk and buying a 13'. As with everything, i do not purchase a first year of say a new design or model or the latest and greatest until all snafu's and problems are ironed out.

I think it's crazy how ppl don't think this a problem or how they say dam put 65 miles on the sled no problem, but really it can happen to anybody!!! Doesn't matter mileage color combos le or standard. I didn't think it would happens but once I saw it with my own eyes how easy it went (not riding hard) compared to what we where hitting earlier in the day scary, sled had over 100 miles on it also and was a retro 163 for all the people who think they got s system trying to figure out the bad batch, please let there be a aftermarket shaft some company makes you guys could make a killing right now!!!

One failure I know of also ruined the track....any others like that?

JFYI.....in the testing we do at my normal job, standard practice is 4 lifetimes at a variety of load conditions up to well over 100% of design load.....the equivalent of 80 years of use and it cannot fail. Then a test to failure which often exceeds 150% of max load even after 4 lifetimes of use. This is not unusual in the test world.
At accelerated test levels something like that shaft could easily be proven in a few days.
My guess is it was not tested.....or these threads would not exist.
