Block off plates

I did my plates yesterday. Amazing! Popping on decel is all gone. While I did them I changed the plugs which really needed it. They had I would guess 60 000 kms on them. It is like a whole new bike. Checked the gap on the old ones just out of curiousity. The worse one was only off by about .005". Stink factor was also greatly reduced. Highly recommend doing the plates!

It was also nice to talk with you Z1-Jockey. I always like to meet members of WT.

what did you use to block off the air box openings etc where the PAIR hoses used to connect to ? I'm assuming you removed the entire PAIR system.

Yeah its all gone. I found some rubber caps in the help section at Canadian tire. It was so easy to do and ALL the popping is gone. Sounds so much better I wish I had done this years ago. Today I am going to do the wifes' bike.

We put the ss brake lines on the 600 yesterday.
It was colder in the garage than out on the street.
All that concrete is still at winter temps.
So, doing your work outside is actually an advantage at present !
Thanks for the tip re CTC, and no doubt Home Depot would be a default for those stateside that are not blessed with CTC.

doing the block off plates will actually reduces the stink?!?!?!?! i would think it would increase as there is less o2 in the exhaust for the catalytic converter to do its work.

I found the stink to be increasing lately. Could have be the really old plugs or the plates. Not sure. Stink is a lot less now anyways.

I think the only 919's sold with catalytic converters were from California...

Don't think bike's need to meet emissions most other places. I'm from Kitchener, Ontario, Canada.

I love Mother Earth but my motorcycles lose all the smog crap. The block off plates definitely made mine run smoother on decel, they look trick and make it a whole lot easier to replace the spark plugs too.

Apparently black y pipes means no converter inside and silver means it does.
And the canister hanging down below on some USA bikes is an evaporative collection can and not a catalytic converter.

I did this to my bike and there is an increase in engine noise, is this common or did I do something wrong?

I have stock pipes.

did you get the plates or cap off the stock housing?

if you got the plates did you leave the reed valve in?

I am not sure that the 919 plates will fit a 599. If you are interested in a pair. shoot me a PM.
