Duggle.. I will pull one of mine tonight and give it a quick measure. I forget the exact thread it had. We will get you fixed up thought.

Something handy for everyone is one of those screw and bolt size finder things. Usually a flat piece of metal or plastic with lots of holes and pegs. I have a couple for regular US size items but none for metrics. Guess I will need to start looking for the same in metrics. They become helps for finding screw and bolt sizes. I have never seen on that will also give thread size, just the bolt or screw size. But once I even had a SAE thread size gage. It looked like feeler gage pack but the material was thicker and had a section of tooth shapes that could be set into the teeth on a bolt. Find one that fits and the gage tells the tooth pitch etc.

The gages I do have were given as advertisements but are often helpful. I will look to see if any metrics are available and post on the forum if I find some.

In the meantime try this input. Basically just measure across the bolt hole to find the size for a starter.

EDIT: So far this is the only place I found with reasonable price. It may be something you can use. The ones I have, and they came as gifts, advertising, hand outs, sometimes come in very handy. Handy but not worth the high dollars some require. I looked at the company that makes these handout types but they want orders of at least 100 at about $1.50 each.

A few at www.amazon.com/Screw-Bolt-Drill-Bit-Gauge/dp/B001M5K9OY for $4.36.

And here at less than $2.00

That is awesome of you, thanks Damin.

I'll probably head to the Ace Hardware on Saturday and get this bolt business worked out, one way or another.

[damin69]

Ok I did not measure all the lengths. This is the top bolt. it is an 8x1x70

I think the bottom is the same length.

Thread pitch is also an issue, coarse, regular, fine, etc. The typical 'regular' metric standard I think is 150. If you have an Ace Hardware nearby, you can buy some bolts and see how they work. They'll happily take back what you don't use or need.

[dugglebogey]

You're a life saver. I'll go to the Ace Hardware in town first thing Tomorrow morning and get some 8x1x70s and give them a try. Unless the rapture occurs, then all bets are off.

Actually, if I can make it there before they close on my way home, I may work on it tonight. That way the rapture doesn't even come into play.

Print out the pictures Todd posted, it'll help in matching up a new one. Those look to be coarse thread. I hope to have my scooter running by 6pm local time Saturday, I figure I'll need it to maneuver around all the zombies that will be walking the streets after the rapture.

I ran out to a Home Depot at lunchtime and got the closest thing they had, which was 8x1.25x70. It was the only 70mm bolts they had. I'm thinking a quarter of a mm is probably in the range of error here. They were only $1.25 each so the price was right to give them a try tonight when I get home.

[damin69]

DB give them a try. I am not 100% on the pitch 1.25. just try turning them in if they do not screw in easy DO NOT force them as you will cross thread then you are up a creak if they do not screw in all the way by hand to the point you are snugged up against the muffler bracket the pitch is wrong.

[dugglebogey]

They fit perfectly, I didn't have to force them at all. They tightened up great.

I added oil and drove it around town. No leaks, it runs perfectly.

Thank you for the measurements. they really made this a no-brainer.

[akafrost]

I had one of those missing and found it at ACE Hardware for about $1.25 each.

did you find your new bolts yet? I used a thread finder on my bike when I lost the bolts to my swing arm and brake caliper then I used a thread die to make my own bolts you can find all of this at grainger.com

[dugglebogey]

Yes. The bolts I got at Home Depot worked perfectly.
