Title: KX500 running problems
Post by: dans89kx500 on November 23, 2007, 12:45:31 AM: Hello,

I've had problems with idling, now my problem is a bit different. When I ride my kx500 with the choke off, it cuts out, runs very ruff and wants to die. Then I pull the choke up, the bike seems to run fine or a lot better.
I've to the point of just replacing the carb with a different one. If replacing is my only option. What all years interchange with the 1989 model PWK V461DB01?

Thank You,

Sounds to me like you simply have a partially plugged pilot jet.

Sorry for my lack of knowledge

Post by: tharden on November 23, 2007, 10:56:32 AM: Cleaning the Carb would be my choice, but I would also check the compression as well. A two cycle engine can have these same symptoms when low on compression.

Post by: dans89kx500 on November 23, 2007, 11:30:34 AM: What should the cylinder compression be for a 1989 model?
I'm taking out the main pilot jet now.

Post by: dans89kx500 on November 27, 2007, 01:37:48 PM: Yes, the bike runs great with the choke on, just when the choke is off it cuts out and dies. I'm having a local bike shop look at it now. He says its a main pilot jet. I will get the bike back this friday. Thanks for all the sugestions.

Post by: dans89kx500 on December 01, 2007, 02:24:17 PM: Well, my bike is finally fixed and running great (I took it for a ride today). The pilot jet was the problem, they replaced the 60 jet with a 65..... I do need now to replace a worn intake boot real soon. Anyway thanks for all the info. Great web site!
