KX500 WOT ISSUES

(1/5) > >>

jforbesautotech:
Hi, I have a 1995 KX500 that I bought from a buddy and needed cylinder work so I had a sleeve put in the cylinder. I got the bike running the other day and it runs good other than WOT, it just falls on its face at WOT.  I would just like to know what all would cause this problem. I am at about 3500 feet and the main jet is 168, dont know if it is starving for fuel at WOT or what. Any help would be appreciated. Thanks

Does it eventually die at WOT or instantly.  Could be many things. What have you checked so far? Cam.

jforbesautotech:
It is pretty much instantly when you get past 3/4 throttle it just doesnt have anything and you can hear the motor struggling when you hit WOT. I havent checked a whole lot because I dont really know what to look for. I checked the reeds when I put it back together and they looked pretty good no cracks or anything and also checked the main jet and it is a 168. I just dont know where too look for the problem. I thought about putting a reed spacer and maybe new reeds but I dont know if that would do anything or not. Thanks

Did the bike run before the resleeving? If not, how long did it sit? Whats the plug look like ? Put a new one in cheap B8es then check it. Did you change the fuel ? New fuel will help , also clean the carb ,a carb with water or excess oil in the bottom will shut off like that when you go to WOT. Check the carb first then go from there.Keep us posted. CBX

The guy I got the bike from said that it ran good and it only sit for a few weeks until I got it. I changed the plug when I put it all back together and also changed the fuel and cleaned the carb. I done all of this prior to riding for first time. I am running amsoil saber professional at 32:1 ratio. Thanks
