I just got and end cap for my stock ds 650 do i need to change jets? what size? need help.

 

I have an endcap and I had 165 mikuni stock and was told to go to a 170 mikuni, but I also have the ported intake 11.2:1 je piston and I am running the 175 main jet and love it, all jets are mikuni of course needle in stock position- 4th groove, someone please correct me if I am wrong, let us know how it works out

 

175 jet with end cap works great,with the needle in the richest position..[img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-sad.gif[/img][img]i/expressions/face-icon-small-blush.gif[/img][img]i/expressions/face-icon-small-sad.gif[/img][img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]

 

I run a 175 in the stock carb and I swap 3rd and 4th position on my needle depending on altitude. I ride 2700ft. and ride in Lake Havasu....think its like 600ft. The heat and the cold also play a big factor for my areas. So you may get a bunch of different opinions on this.
