2003 WR 450 electric start problem.

17 posts in this topic

I just bought an 03 WR 450 and took it out for the first time Sunday. Electric starter worked great all day. I did need to use the choke everytime but oh well. I went to load it up and it just clicked like the battery was dead. The battery is supposedly brand new. I tested it and it was at around 11.4 volts. Do I just need to charge the battery or do I have bigger problems. I was running with the lights on but would think this thing would have a decent charging system. Any help would be appreciated.

Sounds like your too lean on your jetting. Try one step richer on the pilot and main to help. My 03 starts great! with this combination. Did you check to see if the battery was charging with your voltmeter when the engine was running? When dead or near dead the battery takes a while to charge back up.Turn off the headlight to charge it faster it takes a while. The starter is spendy so the less grinding you do with it save you money latter.

Lots of the early 450 had weak starters, mine included, I think. But AFTER a day of riding it is usually OK. It's at the beginning of the day that it's weak. Check your charging system.

its actually not a "starter" at all. its a "re-starter". Thats what KTM calls them to cover their weak starters. They could have put a bigger one on there but that would have defeated the purpose of "fighting the fat".

My 03 starts in gear out of gear and upside down. It's the best starting bike I had or been around. Push the button and it runs, my 05 sucks on starting compared to the 03. Buy a battery if you are not going to check the battery or the charging system. I say this because if you burn up the starter it's major dollars to replace. Besides jetting being lean the intake valves could be tight causing hard starting also. Lean running engines the valves get tighter much quicker. The good part is you still have a kick start.

I appreciate your input Desracer. i think it is lean. it pops on deceleration. I also always needed to use the choke. When I try to start it even with a battery charger on it it just seems to click right under the seat. i want to fix it correctly and as cheap as possible.

I also could be the brushes. They are a cheap part to get, but painful to get at. Just buy a battery anyway. Dont replace them until you are positive about the battery and connections. If you have to pull one out of the car to test. You manual also gives you relay troubleshooting procedures for the relay.

Did you have the Batt fully charged, or did you just have the batt charge "on it" at the time of turn over?....

Put a volt meter on it while you are trying to start it.....if it dips below 10.5 volts or so the battery is shorted and it won't matter if you have a charger hooked up or not.

what is that is clicking up near the battery? Is it the solenoid?

The clicking under the seat is the relay. The red wire comes off your battery and right to the relay. Your problem is almost for sure brushes on the starter motor. They are a bitch! I just replaced my entire starter motor because my gear on the armature was worn as well. If you remove a bunch of crap on the right side of the bike, you can get the starter out on that side. Good luck if you decide to fix the existing starter motor.
