Your product is excellent, no real complaints. Except that it would be nice for a little more installation procedure. Not everyone is a mechanic that installs engines all the time. As an example, the engine mounting holes are not threaded and some other holes like the muffler bracket holes. I figured out that the original bolts were high quality self tapping screws. But most people I saw online doing installations had no clue and where tapping the holes and or using Nuts and Bolts which is a bad idea if they don't use the proper hardware. A little installation guidance instructions would help your products be installed properly. But over all a very clean install and a great product. Thank You
