Hey guys,
So I thought Id take some "pre tune" notes on the setup I am running right now.
I took it for a ride the other day where I could really stretch its legs and see how my bike performs.
I was hitting a flat spot around 5k and it would just stumble. So, I raised the needle one notch and now it pulls fine and it stumbles at 7k. This is where I stopped and figured I need to go bigger on the main jets..
The bike is jetted like so, unmodified by me.
Mains-135
Pilot-25
4fp21 needle, X-6
stock airboxs, crappy shorty mufflers that I repacked with fiberglass.
Thats pretty much the stock setup for the 360s..
However, I notice that the stock pilot jet is supposed to be 17.5 according to my Haynes manual.
Should I be worried about this jet being too big or do you think a 25 size pilot can still be compensated by the idle mix screw?
I did notice after I took it out for a few miles, It would not idle.. Which I think its too rich on idle. I could smell gas. I had the idle screws out 3.5 turns. I could only get it to start if I had the throttle wide open and only then it would just idle for a minute or so before it picked up again..
This is on top of having a cold idle that will hang at 3k when i rev it up..
Im thinking I can tun the idle screw in to 1 turn, and lower the float levels and see what happens..
I know these jetting posts are very tired at this point, Im doing a ton of research and reading all over the place. I think im on the right track here Id just like some confirmation on the direction om going.
Thanks.
