Back in the day I used to reuse head bolts, then came non reusable bolts. Has anyone used the bolts that came out for reassembly?

Yes, they can be reused. Normally the non reusable ones are in a "torque-to,-yield application where the bolts are stretched to their limit when torqed. Valks are nominal torque per quality of bolts.

I reused mines, but then they're only $1.25 each x 16.

Thanks for the answers. I did order bolts but it is going to take a bit before they come inn. Basically I'm getting impatient and want to get it back together. I haven't been able to ride yet this year and it's not the weathers fault.

For some reason, the manual doesn't specify the torque value for Bolt 25 on the relevant pages (8-0 or 8-22). Each head has one of them and it goes near the bottom edge for a water jacket or something. It's only 6mm diameter. You might hash mark or dimple the bolt at 12 o'clock before removing the bolts. You can try fishing for the torque value using a low range torque wrench but the torque value is so low (bottom pic.) that accuracy is questionable.  The waterpump bolts happen to also be 6mm so I used the same torque value for Bolt 25 that the manual specified for the waterpump bolts.  The waterpump bolts range in length from 12mm to 95mm but all of them have the same torque value of 9ft-lbs.  |

I'm thinking the torque on the 6mm bolt isn't critical, but if I want to torque it I would convert to inch/lbs and use a inch/lb wrench. 108 inch lbs. I'll look at my wrench when I get home and see what it's range is. Thanks for the info.

tech manual, page 1-13 torque values, lists four different types of 6mm fasteners and required torque ranging from 6.5 to 9 ftlbs.

muffler 6mm acorns are 7ft-lbs. Avoid removing zee mufflers whenever possible.

"I'm thinking the torque on the 6mm bolt isn't critical,"This 6mm bolt is situated at the very bottom edge of the head. I wanted to make sure the bolt was tight enough as it's the only bolt that keeps the water jacket sealed to the engine block on that edge. And a little bolt at that. I did use an inch-lb torque wrench.  --------------------------------------------------------------------------------------------- "tech manual, page 1-13 torque values, lists four different types of 6mm fasteners
and required torque ranging from 6.5 to 9 ftlbs."Yes, in fact, it does. 6mm flange bolts in my case

So I will ask the question.
What was the reason for removing the heads?

Ron is right long story, I was doing a few different maintenance items. One was valve adjustment, another checking timing belt tensioners and a couple others. Long story short I hit the starter button with the tensioners off the motor. I bent a valve on the right and after replacing that head had tapping noise on the left side head, so replaced it also. Morale of the story, stay away from the controls when you have a buzz on. |

Now you tell me lol. Seriously I should know this, and have done it before, I do electrical for a living. Just a season full of brain farts this past year. Not a good excuse because it didn't go to the brain but I'm gonna blame it on the cancer  |
