Sirius in Canada(http://www.siriusconinc.com/pro-detail.php?pid=&product_id=176) do a jet "Kit" with several different sizes of mains. What size are yours as 500 ones might be a bit bigger and I have a few of those somewhere
-
Thanks for the reply Bryan the stock size is 75 for the main jet if you have any that may help I will buy them from you thanks
-
Im running with pods,yoshi and dyna ignition on my 400.
I increased the main jets to 85 and as yet have no problems.
500 jets are 100 and may cause her to run too rich
-
Thanks Norn Ive a set of jewellers drill bits and the jets I replaced will try gong up in .05 mm increments just to see, where did you get your 85 jets?
-
I cant remember if it was "sirius" or "jets r us"
U are nearly there.running pods can be tricky.all the advice telling you not to remove the airbox is right.
U also may need to increase the idling speed
-
I wont have anything that small mate but I am sure sirius will alter the jet sizes in the "Kit" or I know they sell individualy or sets of 4
-
Again thanks for the replies Sirius are out of the kits at the moment nrp carbs have 85s so might give them a go it will keep me busy get this right and the bikes finished for now
-
I use redex in every third fill of the tank.
It stops the carbs gumming up when not in use.
-
I have spare size 75 jets if u want to rebore them with your bits.
-
Thanks for the offer Norn but I have 8 of the 75s to play about with did you do anything with your idle jet ?
-
No i didnt do anything with the idle jet but i suspect i ought to.
I just turned up the idle speed to about 1600rpm.

Norniron, you will never get your beast to tick over because of the exhaust you are running ;D
Are you back on a STD air box ?
