WR450 cant adjust fuel screw - too lean?
Posted December 31, 2010 - 11:05 AM
Tried to set the fuel screw as per the sticky. I can screw the screw over the whole range and dont notice any discernable difference. If I screw all the way in, bike dies straight away. Still pops on decel.. thinking too lean a pilot?
Didnt install any of the jets in the GYTR AIS kit as I had read they make the bike run too rich.. thoughts/ideas/opinions.
Outside temp around 50...

Set the fuel screw opened as little as possible and have a good idle.
It is possible your idle is too high when setting the fuel screw so much so that you are also on the needle a little. Try lowering the idle speed.
Not sure how long you consider sitting for so no opinon there.

I have set it at about half a turn out.. seems to be idling nice now and the return to idle after revving is definitely smoother and quicker.. now need to find the best idle setting for the rekluse...

You tweak the fuel screw to make the bike run as fast as possible. Then go back and reduce the idle speed if possible and again, re-visit the fuel screw and see if you can make it run faster. Keep doing this until the idle speed is reduced as much as you can and the fuel screw is making run as fast as you can. Sort of a balancing act. Then..... you can increase the idle speed to a 'normal idle'.
