should be ok. I also rejetted. I believe other forum users have also removed this not vital piece. If you search the archive and use the keyword "octopus" you will come across one of my posts which explains, in detail, how to remove the octopus and rejet the carb.

After I pulled my carb, this octopus did not go back on in the same postion. So I am thinking of removing it. In your post you say to change to a #100 pilot air jet and a #65 start jet. Does that also go for us up in altitude in CO that are YZ timed? I assume the blocking caps can be picked up at any automotive store. Are they all the same size or do I request a certain size?

If you continue to ride above 6000 feet you might try changing the air jet to a 100 and leave the stock start jet (#60) in place. But I would definately change to the 100 air jet.
You can usually just pick up a set of assorted sized vacuum port blocking caps and just use the ones which have a nice snug fit. I got some multicolored rubbery vinal ones at I think Kragen but any well stocked auto parts store will have them. The larger caps are great to put over the firing end of a spare spark plug for throwing in the fanny pack.
