I am currently rebuilding the top end on at 2004 ttr125. Using a torque wrench I snapped an allen head bolt before it reached 7ft-lbs. This got me wondering, are the head bolts torque to yield? If so, how safe would you feel reusing them once? twice? For reference these bolts should torque to 16 lb-ft.

Thanks!

P.S.
Forgot to mention for those wondering the bolt snapped high enough up to be removed easily, the mechanical gods smiled upon me today I will have to be sure to up my offerings of knuckle blood for the next couple weeks ::notworthy::

Maybe just a weak defect bolt who's time was up?

I would not be too concern until you have another one break.

The TTR's are made in China, and IMO, they are not of the same caliber as the Japanese made Yamahas. We have had several of our rental TTR's stretch head bolts. Definitely do not reuse the head bolts - ever.

Was your torque wrench a Harbor Freight product?

Thanks guys. I went ahead and continued with assembly and put the 2 smaller ones on order. the other one snapped before 4 lb ft so something isn't quite right. When I put the new ones on I will use an Allen and just get it tight. The torque wrench seemed to be working fine but don't want to snap 2 more.

Not sure if you've checked or not, but most of the cheaper toque wrenches aren't accurate at 5-15 lbs. Even though they show on the scale that it goes down to 5-15 lbs, unless it's a quality tool it won't be anywhere near accurate.

I didn't consider the tool being bad. I tested it on a larger bolt in 1 lb increments and felt like it added pretty linearly. Is there a better testing method for a layman?
