Yoshimura Pipe help.......

[acme]

Any ideas how to remove the muffler from this pipe? It's a mid 90's Yosimura 4-1 pipe for a GS 1150. The 3 screws on it do nothing, don't even touch the pipe.

[Spyderman]

yes they do
removing them will allow you to take the can apart but be warned it wont be easy
others here have done it and can give you more into on how to do it

They get like that when they've not been apart for while. Remove the screws and have someone grab the other end and twist and pull.

[TheCafeKid]

The three screws hold the canister to the collar. Reomove the screws, pull the can off, and there should be a set screw (usually) holding the collar to the midpipe. The baffle is removable, and repackable and will come off with the can.

You need a bigger hammer.

I have an ancient Kerker 4 into 1 into 2 exhaust on it now with two 2" K Series mufflers. The whole system is straight-thru, probably 1 oz back pressure
I had to raise the 36mm flat slide Mikuni's needle all the way up to have good power vs the Yosh pipe with the needles mid-way.
Debating either to put the Yosh back on or leave the Kerker. Kerker has tons more torque and top end , Yosh is quiet

i had the same pipe/same RS carbs/1150E
i ran the needle in the middle/ a 135 mains/15 pilots/mixture out 1/2 turn/screw removed from the pump rod to let it work all the way through.
tork monster with the pipe for sure.
oh,

I ended up with a 2nd gen GSXR 1100 4:2:1 Yoshi SS pipe on my ED. I'm still running the 1150 CV's with a 145 Mikuni main jet. The 4:2:1 has much more lower end that my older 4:1 Yoshi pipes. (Ask Bill ; he knows )

Mine ran too lean with the needle in the middle, I would turn the throttle and felt like just air going thru the ports I run 130 main jets, but the 2" baffles are too loud for me
