Has anyone installed the Block Off Plates that come from 2 Wheel Dyno Works?
Did they tell you that you were suppose to chisel off part of the plate before installing?
They told me this after the fact and I am not sure I am comfortable with doing that. Not to mention the fact that they provide this information after the fact. Not on some piece of paper, or some type of instructions in the box. I mean this information is needed ahead of time.
Don't the Graves plates have a cut out to make room for this?
I was actually wondering why 2 Wheel Dyno Works Plate's didn't have that cut out, but I figured they are professionals. If they thought I needed to know something they would tell me right?

We have had a few members over the past months run into this issue, so we want to address it for everyone to alleviate any future headaches! I also think there may have been some miscommunication or some sort of misunderstanding when answering jasontechpro's question, so we do apologize if we were unclear somehow.
The AIS system on the FZ-10 has the exact same system as virtually all Yamaha, Kawasaki and Suzuki twin and inline-4 cylinder engines, with one extremely small difference. Yamaha decided that, only on this model, they were going to leave a very small "nub" that sticks up on the front of the mounting surface for the AIS system. Whenever we install these block off plates in the shop, we simply pop this "nub" off with a flat head screwdriver or a chisel. The metal is that flimsy that it just flies off with a slight tap.
The block off plates that we manufactured are universal to fit all of the aforementioned systems, so when using our block off plates (or anyone else's that don't have a machined notch cut in the bottom of the block off plates) you simply need to remove the small metal "nub". Issues occur when this isn't done, because the plates will not fully seat and cover the AIS port. This will allow excess fresh air to enter the the exhaust side of the combustion chamber and result in minor popping and backfiring.
The only other solution would be to order a set from Graves or another manufacturer that includes a machined notch to accommodate this "nub", but they are a bit more expensive and removing the metal "nub" takes literally seconds.
We hope this answers any questions anyone may have regarding our block off plates. If anyone has any other questions please reach out to us directly. We are always more than happy to help!
