Starter woes

I hear of others having starter problems on their 03 wr450, anyone have a starter start squeeling and not turn over??

And will a bad battery make it to where there is no spark??

You know the more I here about the problems of the starter the more I am glad to have old leg power :naughty: that sucks that your starter died does it come with a kick start back up?

My starter has never worked right from day one!! The starter mechanism is a POS in my opinion.

I was working on mine today and I decided when I get the guts I am going to pull the idler gear out. I'm not comfortable doing work inside the cases, even something this minor. But I'm going to try popping it out. Only the leg has worked right from day one for me. Yamaha sucks for what they have sold for electric start. It worked better on their web site than it ever worked in real life.

I have read a lot on this and it seems like a new battery guarantees nothing.

Sorry I don't have an answer to fix it, but mine has never worked correctly.

Yes, thankfully it does have a kickstarter.

my electric start kicks it over everytime, even when it hasnt been started in a week, it takes 1 or 2 trys but i just turn the choke on twist the throttle about 1/4 turn, then let off hit the starter and boom, no manual labor.....but when it hot it works 100 times quicker, (so first try) just pull the decomp. give it 1/4 gas let off hit the button and bam!

if you read the post, he said it is an '03. looks like you have an '05. by the way, that's not a decompression lever, it's your hot start.

you stole the only 2 sentences i was going to type. :naughty::naughty:

womp, womp, i figured it was the same basic shiat for the bikes.

Yeah, that sounds like the first year I owned it. Now.......

i really didn't mean to come off too harsh. i guess some of us with '03's are getting a bit punchy when it comes to starter stuff. first, a lot of 'em sheared flywheel keys at weird times. some in the driveway. some in the woods. some never. yamaha came up with a cheap fix and said that was all they would do. period. we kept shearing keys and even broke side covers. yamaha turned a deaf ear. damn if the '04 didn't come out with a new idler gear. (it's under the little round cover and acts like a one way clutch sort of thing) we found out the parts would fit the '03's but yamaha wouldn't help the '03 owners. $200.00 bucks later,problem solved and we're riding again. with two years on the bikes, a lot of starters are going tits up. a bunch have dead spots in the windings and will only "click" when you push the button. if you rock the bike and get the starter to rotate, it might turn over. might not. very few if any '04's have reported the problem. now we're having the starter clutch on the back of the flywheel fail. you can tell when it's going by the god awful noise it makes. sound like it's breaking all the teeth off a gear. OK, i'm done "venting".

The 03 starters are defective. Get an 04 starter, this will solve your problem. Im surprised that you havent broken your woodruff key.

quick question, kinda off the subject, whats the difference between a hot start and a decomp. lever? stupid ? but its my 1st 4-stroke.

thx, guys

Thanks MTRABLUE, I also have a 03. After the 04 upgrade I have had no problems. Fires right up. If it has sat for a long time I wont even press the electric start. Ill just get off my lazy butt and kick it. No need in putting undo stress on the starter when the bike has been sitting. Once its warm it will fire right off with the electric start. The fact is that this is a small starter designed on a race bike, with the intention of being light. What that means is yes it will wear out. Now the question that I have is, there a difference with the actual starter, (not the torq converter) on the 04's. So when everyone chimes in and says get the 04 starter, do they know what they are talking about????? Or is it they mean the torq converter that needs upgrading????? And about the saying that I hear here all the time "03 is a bad year stay away from it" I LOVE MY 03. Cya Stinson

Long live the power of the leg!!!!!!!

Now that I learned how to properly start my bike (thanks to fellow TT experts) I am not missing that magic button.

Well that sounds exactly like it.

I got the dad-gum-thing to spark and now it just won't start. One of my friends thought it might be that it broke that key inside there. So I don't know. I finally took it to a specialist. I hope with a little therapy it does the trick!!

Decomp lever opens an exhaust valve to dump compression for starting. These bikes had a hot start knob on the carb, it looked like a choke, but a red knob usually. The hot start is now up on the bars where there is no more decomp lever. The hot start creates an air leak or air bypass to lean out the carb making it eaiser to start when hot. Instead of reaching down on the carb, you just pull it with your finger on the bars. Makes for a quick restart. All models with the hot start use an auto decomp camshaft. This would be the 03 to current.

Yet! :naughty: I didnt miss it either with my 426 at first, but sold it ONLY for the e-start model. :naughty:

You can get the starter out without removing the case by pulling rear exhaust of then loosening header bolts and twisting header up.Remover oil 3 way pipe then undo cable and 2 starter bolts then pull back and lift out.Takes 5 minutes tops.
