jetiing ideas from aussies to suit our conditions

the standard needle is OBDVR 3rd clip position .... 182 main ... 40 pilot jet ..

is your compression ok .... have you checked your valve clearances .. it could be time for a rebuild ...how many hours on the bike ?

Hi
Madpugs
I have a 05 550fe and i found the standard setting best as Whosahberg posted...

But i have lifted the needle up one groove
is your exhaust standard...?
I did try a 185 and 188 but found the bike to be a dog on WOT.

I have a fe 650e 2005
here are my settings am slowly coming down on the main jet size had 182 in it might come down a little more though
Jet needle is the OBEKR on the fourth clip from the top.
Main jet is 175.
Idling jet is 45.
1.5 turns out on the mixture screw
Everything else is standard in the carburettor
High compression piston
straight through akropovic exhaust

Go smaller on the main and you will notice a big difference. If it's too small it will surge. It seems most dealers I have dealt with for both 'Bergs and KTMs jet too rich.
My 650 is running a 165 and the top end is so much better than stock now.

main air jet stock at 200 means 185 main works by producing more tourque than a smaller main.

change the main air jet from 200 to 160 or 165 and then the smaller main jets work well giving more power and more tourque without going lean at high rpm

if the main jet gets down to 150 or smaller then it needs a 155main air jet

simply put: if the smaller main jets crispen your bike up nicely and make more power but its going lean at high rpm and peak tourque is reduced then make the MAJ smaller to fix it.

stock jetting on my bike was 160main 200MAJ EKR needle clip 5 with 3 seconds squirt, it went lean at high rpm after the acellerator pump stopped squirting. the pump is a bandaid to cover the lean steady state settings needed to pass emmisions testing so I got rid of it and changed the MAJ.

same applies for the PAJ /pilot and needle, if the bike likes the needle dropped but it starts to gasp then the lean spot can be fixed with a smaller PAJ and then a smaller pilot to suit see owners DOC for taffys chart of pilots and PAJs. there possibly should be such a chart/s for the main/MAJ too.

theres not much difference between the countries it seems when everything is done properly. just MHO 1or 2 sizes bigger on the main in aust seems common. most people have salt in the cupboard a pinch or two may be needed when reading my posts on jetting.

I like caltex vortex98 over bp ultimate, they need different jetting too.
