How to measure bolt pattern?

[thefox]

How would I measure the bolt pattern? Is there a way that I could drill out a 3 bolt pattern in my 4 bolt rims without getting them off center? My Yamaha 200 needs rear rims and I have some, but they are from a honda 185s. The yamaha is 3 bolt and the honda is 4. Can I make the honda rims fit or should I just get new ones? Thanks

That would be very hard to do IMO. If you dont get them 100% dead center you would have a lot of wobble.

Take it to a machine shop if you want it done right. Thats probably the only way that it will be perfectly centered ;)

Cmon dude you actuall want to rig your ride up like some chump. Just save your money and get some blinging rims that are proper.

To measure
measure from the center of one bolt to the center of another bolt accross.
Mine were 6 1/8" which is 156 mm
so my bolt pattern is 4x156
4 studs at 156 millimeters accross.
once u figure out that you can find rims on E-bay or get some new ones. Dont rig up your ride it just makes things worse in the end.
