Diameter of bolt pattern
 

Does anyone happen to know the diameter of the bolt pattern highlighted in red here? Want to laser cut some wheelie bars knowing what the diameter there is suppose to be would be a big help. Can't find it in any docs I have seen.

I made a paper pattern for mine, pulled three bolts and placed the paper over the holes, the dirt in the holes made a mark I could follow.. All I used was a C shaped piece of 1/8 plate.....built a tab off it to attach the lower bar, and mounted the upper bar to the place where the rear hitch would have pivoted on my 122. Simple, light, and it works.

truckntran, you were suppose to make it easy on me... I was cheating by asking. Nice explanation on how to get it though, Thank you.

Seems to me like you could find it mathematically if you only knew the distance between two bolts. There are 6 of them and they are on a 60 degree spacing. You are building equilateral triangles, so the distance between two bolts "should" be half the diameter of the bolt circle.

I've had a couple brewskis mowing the yard (first time this year!) this afternoon/evening, so if this sounds like BS, it probably is. It makes sense to me though. :beer2:

I'm pretty sure that's right.

Or you could just spent the $12 and order a couple of gaskets, they probably need changin anyway....I'm simple like that.:)
