I'm a new member at this awesome site. I have done a lot of reading, and there is a ton of info. and good advice pertaining to everything KX related. I searched, but was unable to find out any info. pertaining to the specific problem that I'm having with my bike. Here goes the story thus far...
I just got a "91 KX500 a few days ago. I had to work on it, before I could ride it. Just some simple stuff, nothing major.
My Q is about the carb. When I finally get the bike cranked (my foot and leg is killing me!), it will not idle on it's own.
I have to turn and hold the throttle, just a little for it to stay running. This is most inconvenient when riding and having to slow down, as the engine will almost shut off completely, when the throttle is let loose. I do not enjoy having to kick the "!@#$" out of it, to get it started again!
Could someone tell me how to adjust the throttle and/or the carb to make it idle without having to turn and hold the throttle? I tried adjusting the long screw on the left side of the carb, while my wife kept the bike running. No matter how much I adjusted that screw, it made no difference in keeping the motor running on it's own. Is there another screw on the carb somewhere for adjusting the idle? Or, is the idle adjusted by the throttle cable?
One other thing I've noticed is that the bike seems to run too rich. Specks of oil droplets come out of the exhaust. It's almost like a black tar, I can see where some of it has built up and seeped from the muffler and pipe connection, and some from the exhaust header to pipe conection. I hope it's comming from the oil in the gas and not from the oil in the crank/tranny. The oil level in the case is at the half way make of the case viewer.
I took the spark plug out and it was oily. It takes me a lot of kicking, and it is hard to kick start the bike. It takes a while for me to finally get it running! I need to get some steel toe boots or something! These tennis shoes don't protect my foot so well!
I got a matienance/repair book ordered, but will not get it any time soon. I'm gonna drain the gas and try running the bike with a little less oil to gas ratio. Hopefully, this will eliminate the oil droplets and thw mess it is making. The oil mixture was 50 to 1, so that may be the culprit. Next time, I will mix it 40 to 1.
Any advice, links about the above would be greatly appreciated.
Thanks
