Starting ktm 525 with 570 kit

Recommended Posts

Can someone please help me? I just got a 2004 KTM 525sx with the thumper 570 kit in it. It has the electric start added to it but it will not even turn the motor over, unless the decompression lever is in. I can barely even kick the bike. I tried to find the compression stroke, and then use the decompression lever to go slightly passed it then release it and kick. That method seems to work the best, but still wont fire up. I adjusted the valves to .005 on both. The carb has an aftermarket air/fuel screw on it, but it was not screwd in at all. I believe the stock setting on the screw is 1 1/2 to 2 turns out. Can anyone please help me? Thanks for reading, sorry so long.

Your bike should also have an auto decompress on the Cam. It sounds like yours is not properly adjusted or not functioning correctly. The decompression lever on those bikes was not really necessary. I had an 03 and broke the decompression lever shortly after getting the bike. I never replaced it. Also, if the valves are not properly adjusted the auto-decompress will not function correctly. Good luck!
