It's easy to say that if you have access to a machine shop but for me $125 would be cheap compared to being broken down miles away from home and having to push your bike for miles or hours. Try not to get caught up in trying to mock something up because you'll end up paying the same if not close in labor and materials.
Build for reliability
So I got it all mounted. It definitely gave me some trouble as originally expected. After I ended up building the bike twice myself and realized that neither of the mount I bought were going to work well. But thanks to Norm at VMB for helping me mount the engine. After that It was on me to make the bike perform. AND PERFORM IT DOES.. Would love to quiet the idle a little bit. but I don't think this CNC thruster exhaust calls for quiet. hahaha.
