...ear shave

So I'm new on here and found a old post from lance328 where he was selling "Earshave and Jet kit with Coasters and the extras and Tech support I will sell the kits for $190.00 shipped. If you want K&N filters instead of UNI Filters add $45.00" do anyone know if he still sells these or if anyone else Does? I'd rather get a whole kit than worry about getting wrong stuff, I'd rather do this once..

that said, there's lots of good info on here about how to do an earshave, and lots of people (myself included) who have done the procedure who are willing to help out

Da*m that sucks..
Yeah I think I've read almost all of the post about the ear shave process, just seems too complicated to me..i went to the bike shop close to home to see if they could do it and when i was explaining it to them they were all looking at me like i was completely retarded.. My bike has bigger jets already in it from when the po had the Vance and hines installed, would I need a different set once I do the ear shave?

No. if the bike is running fine now it still will after an earshave. All you are really doing is just junking the stock air filters. It's not really hard to do, unless you want to remove the collecter box? under the tank.....most folks just cut it up with a hacksaw blade...

Wait..so I don't have to junk that box under the tank? Everything I've seen is saying that everything comes out and the pods go on the carbs

Correct. The plenum does not need to be removed, but if you want it out it must be cut up as it does not have enough room to be removed in one piece.

Unfortunately, Lance passed before I got here too, but I have a good writeup on jetting theory on this bike and a spreadsheet that calculates sizes for you.

1. No it doesn't have to be cut. I've done that on at least 4 bikes without cutting them. If you don't want to cut it, just take a few minutes to unplug the wiring harness and feed it back out of the way. It really doesn't take long and it saves more time than it takes. Then you can pry upward and back. Having a second set of hands helps. IIRC there's a coolant hose that might need to be disconnected too, but again no big deal and worth the time to make it easier.

2. If you're doing this job, spend the extra time to yank it or cut it. Seriously, the extra room is very nice to have if you work on your own bike.

Can you post a link to this spreadsheet?

I'm running 38/138 with ear shave, stock pipes to GB, and straight pipes after GB.
Due to unrelated issues, I haven't had a change to try it out.

I'm curious if I'm in the ballpark or not.
