Does anyone happen to know the bolt pattern on the counterweight for the flywheel? I need to machine a coupling for my project. Thanks

 

Anyone?

 

Making a 4 rotor?

 

No building a buggy but need to machine a flywheel for my application. I know it's 6 bolts but I need to know the bolt circle diameter to drill the holes

It's probably a nice round nominal metric number. Put two bolts in opposing holes, set digital calipers to mm, measure over bolts and subtract one bolt diameter, Done! Well... it probably won't come out exact but just round to the closest mm. Bolts are always slightly small and there is clearance in the holes so you will most likely be rounding up.
