I bought the 4 channel as a general shop tool, everything I've used it on so far would agree that it's great! I did have to get a little creative adapting it for my CM400A, turns out the waste gate vacuum tubes from a 7.3 Powerstroke works great for this. I knew it wasn't going to work out of the box on this bike, but that's a Honda thing, nothing wrong with this product.
I bought this to tune up my CM400A, had to get a little crafty with the sniff stick but that's how all good projects go 😅. All and all it works wonderfully and now my bike runs like a top! If you do use the stick at the exhaust tip, I recommend dropping your AFR a bit to compensate for air pulsing in the exhaust.
Good and serves it's pupose, however the addition of a spring (to the securing bolt) to provide some tenstion would be good to help secure it in place (whilst driving the vehicle). I note another review, it fell off and I can see how this could happen.
