Idle impaired WR 400 !!! Help wanted !!
Posted April 26, 2002 - 05:39 AM
I read a recent post on a bike that didn`t idle or hard to start and in there they mentioned that this problem could be caused by the throttle slide plate being upside down... I checked it last night and I had installed it correctly. My pilot screw is set at ~ 1.25 - 1.5 turns out and when I turn it out more the mixture is rich and there is an untolerable bog with black smoke so I`m figuring that I`m ok as far as the pilot cct but I could be wrong. I`ve also tried to fidle around with the idle screw but to no avail.....
So far I haven`t really done a test ride I`ve only tested on the bench... should I go out and ride it for 1/2 an hr to make sure it`s all warmed up and then chk the idleling ?? Aside from idleling, when I went through the throttle range it felt crisp and good thorughout the range. Another thing I noticed is that when I manually hold the choke 1/4 to 1/2 open it seems to be better.... Maybe I though that I brought the motor to operating temperature but I didn`t....
Any advise will be greatly appreciated.

OK TAFFY....I know, I Know, you advocate leaning the piss out of everything.
Take a look at the settings in my signature, They are perfect for my WR400, I run from sea level up to about 5000ft.

So you think that putting in a 48 pilot and setting the screw at 3/4 would solve the problem ?? If so I`ll try that as I already have a 48... further more, I noticed that you have a 100 PAJ but mine is stock (75) so maybe the 48 will be too big ???
