I was thinking of fabricating my own adjustable 2 stroke mounting plate to save money because the adjustable CNC mounts are pretty pricy. The motor I'm getting is the Skyhawk GT5A 66cc. The front mount is I think 1.5 inches & the rear I think is 1 inch. The tools I got allow for cutting & drilling but thats about it. Cant really weld because I don't got a welder. Don't know the exact distance of both front & rear motor mount studs of the GT5A yet but I'd imagine it would be at those measurements or a little past those measurements. Could the mounting studs be placed through the slots of a 4 stroke mounting plate? It seems like they could but looks can be deceiving as I have learned the hard way in the motorized bike hobby. I plan to cut the 4 stroke mounting plate in half & drill some holes for U bolts to attach it to the frame & rase the motor mount plates above the U bolts & U bolt plates with bolt collars & another metal plate under the slotted mounting plate halfs. If this is possible I'll post pics when the project is done. I'm getting the motor & parts to get it up & running in a few weeks & plan to get the U bolts & stuff from my local hardware store if they got the sizes I need.
