Very Nice Drain Plug

It was a little hard to start it going in the right angle because the magnet kept moving it out of alignment. I had to put a socket on it to keep it straight while threading it in! 14 mm wrench versus the original 17 mm size to tighten it down. The smaller size does allow me to use a close end wrench vs the larger original size I could only use a Socket wrench. The gasket / washer is not the copper type it is stainless steel, not like the picture .

Big Bore Kit

This kit has what you need to get overall better gains on both ends. I also bought the 17.5 carb and electric choke kit. After seeing the gain with big bore, decided not to install the carb as there was going to be multiple modifications that needed to be done. Stay with the Big Bore Kit although install the set of reeds to get air and fuel you need. I installed on zuma 08, you do not need the shim the block, just use the gasket, I did thread test and for mine you dont need the shim.

Athena gears

Everything fit very nice. The gears mesh very good. Threads in very good shape. You will need a hydraulic press to change the gears.
