Yahoo, I just purchased my R6 shock

Its a little pricey but it looks great.
Hopefully it will preform as good as the pictures look.

This will lower the rear by 3/4" so I will be lowering the forks to match the correct geometry.

I'm short @ 5'2" so touching the ground is a bit difficult. Before I had lowering links I couldn't get my big toe on the ground XD

Ill ditch the lowering links in place for the stock ones to prevent the bike being lowered to much. The new tail should have a lower seat profile and will allow me to sit closer to the ground.

Ill need a 6mm long 10mm(id) 12mm(od) bushing for it to fit my kat.
Ill source one and post a link below.

AND finally its first start time

My katana 750 officially has a running b12 swapped and running good.

Brief video of the b12 engine running, cam chain I believe still needs dialed in.

Now its time to pull it and send the jugs out to get bored.

My 1216 kit will be arriving soon

Update! After over a year of putting the project aside I'm back and ready to finish it.

The B12 block is disassembled and the jugs are shipped off to get machined.

Picture coming soon.
