Will I notice any performance loss from running my fuel screws at 1 3/4 instead of 1.5 turns? I'm am trying to limmit idle hang.
 

hard to say.I know I tried increasing the fuel screws to 2 1/4 on my SRX and still have hang.So upped the pilot jets to 45 and seemed to help.Just have to set idle around 1600 and seems to always come down the idle.On my 600 sxr the idle hang is crazy,just won't come down quick.I set idle low again,but when comes to starting it runs to low to warm up..its a fine line..
 
but i wont get a bog off the line or anything will i? i just dont want it to run badly afterwards

I don't get any bog off the line with either sleds I have.Larger pilots supplies a little more fuel on bottom end,if you have an idle hang then it is running lean down low.Basically you can try and open your exiting fuel screws up to maybe 2.25 turns max and if idle hang exists then you switch to next size pilot and start with normal setting on fuel screws again.I want to up the pilots on my 600 to see if it helps also.
