2008 FZ1- Fit perfectly, no 'big glob of glue' on the end holding the magnet in. Nice black finish, we'll see if it holds up. Same exact length as stock. I'm actually kind of excited to see what it pulls out of the oil at the next interval. Cheap insurance, money well spent!

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.

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