1 of 5 I can’t recommend these. Sunday, August 15, 2021

This falls into the “ya get what you pay for” category. Stripped two of these studs using a torque wrench at 7 pounds on the head bolts. You may have better luck. Could have saved myself a lot of time buying the ESO High Quality Studs in the first place.

1 of 5 Ugh meh and polini put there name behind these... Thursday, August 27, 2015
taco eater : Feezy from Minneapolis, MN United States  
These have been giving me a headache. They keep stripping on the cylinder side. Bought 8 for two engines and I haven't even got through one. Attempting to use stock ones now. Try the Yamaha m6x106mm or something cause these will make you effin cry bro bags!

4 of 5 One of em broke Saturday, July 11, 2015
taco eater : James Newlin from Seattle, WA United States  
One of these fractured at the threads when I over torqued it (10-15 ft-lb?). Don't be stupid w/ the torque wrench like I was, these can't take much more than spec.

Otherwise, these seem pretty good for my Puch Newport, the length is the same as the originals.

8/22/2014 It says polini on it. Must be a good stud. I stripped my old ones and these went right on. Feel good. I have confidence in these! Just don't tighten your nuts or anything while the engine's hot or you might strip your bolts like the idiot me did. Not with these, with stock ones..

EDIT: 10/25 NOPE FUCK THESE THINGS. One stripped out from just riding. I had set them, retightened after a few cycles, and didn't touch anything around them for a couple months. Then, what do I wake up to, a head leak and a stripped nut. AND I used the tall coupler nuts too.

Edit: 10/26 nope I'm a retard! somehow, the case threads stripped! and i didn't even touch anything! from normal everyday riding! what the hell! so it's probably not the stud's fault....so watch out for your case threads!

Edut: 11/21 - locktite didn't help with keeping the stud in. I suspect these aren't THE most high quality things in the world, and the threading might not be too good, sorta loose if not threaded well

5 of 5 Best e50 studs available!!! Thursday, January 26, 2012
taco eater : Ian from Medford, MA United States  
These are by far the best replacement studs I have used.  They are heavier all around and have much nicer threads than the other janky replacement versions.  Don't waste your money on an inferior product.  Buy these and never look back.
