450 - Nothing but Coughing...Stator? (Pics)

Recommended Posts

I'm posting this here because I don't believe it's a make/model specific issue I'm dealing with. I'm going nuts as I don't get to ride much, now with a huge camping trip coming up friday I've been plagued with mechanical problems...

My Rmz-450 is not starting. Sat for a week waiting on clutch parts and when I got that back together it ran for about 10 minutes of testing then fizzled out. I can kick it over forever and all I get is a loud backfire and blue gassy flame out the pipe every 10 or so slow-kicks. I suspect it's a weak spark after checking many things off the list and seeing a weak arc between the plug/frame as I kicked it over. Here's what I've done so far:

*Traced fuel system-petcock/lines all flowing

*Rebuilt Carb - cleaned all jets/passages, set float height, checked choke/hotstart. Fuel is definitely getting to the motor, the muffler has a barley-burnt gassy smell to it after kicking.

*Confirmed timing is correct. - Cam chain did not slip

*Checked valve spec. - Intake is ok exhaust needs to be shimmed but nothing atrocious

*Checked plug - looks great. Cleaned anyways. Spark had a weak arc from plug tip to frame when grounding during kicks

*Checked stator - Looks questionable. Half burnt but not too destroyed...contact points seem to be pretty clean and straight.

The last thing I did before not being able to start her was shave the clutch basket. Although I was extremely careful to clean off shavings before re-installing clutch parts...could I have introduced shavings to the oil and consequently fried my stator?

Here it is after I had cleaned it up. There was some soot on the stator/flywheel but not a lot...

The culprit? Could this be why it ran so-so for 10 minutes after motor work than died out now nothing??

Any tips are appreciated!

Thanks William1 for the info. I don't have a manual so looks like I need to find one by tonight so I can confirm and try to order a coil by tomorrow AM.

Any tips on where I can get a decently priced stator shipped fast? Rickystator doesn't seem to carry one for the Rmz-450, looks like I'm calling my shop tomorrow...if not..fleabay time.

Try the yellow pages for a company who can wind your stator with new wires. This often is way cheaper.

Good news from Ricky!

Normally I would consider this as spam, but as he is a forum sponsor, he must be a good knowledgeable guy, with a good reputation.

Would you please be willing to share your guarantee and return policy with us Ricky?

We generally give the repairs a 1 year warranty. I just noticed your location, it may not be cost effective to ship the part back and forth for a repair.

Hey guys, figured I'd give an update. I desperately needed the bike ready to go by the weekend when I posted this, I called my local guy and he actually had an Electrosport Lighting Stator in a nearby warehouse. I got in on the bike, and nothing. Did some homework, flipped the two center wires in the 6-pin, a little coughing upon kicking then nothing. Roughly 12 hours of troubleshooting later all I had was a new stator that was confirmed to be bad and more aggravation after a phone call to Electrosport in CA. They pretty much said, "yep it sounds like you got a defective one. Too bad." I generally don't go out of my way to badmouth a company but I was disgusted in the lack of pride a manufacturer could take in such a vital ignition component that people pay top dollar for just to get screwed over and push their bikes home.

Don't buy Electrosport. Do your homework to make sure your aftermarket stator isn't still made by them (Moose, Electrex...). I read up on them and saw their bad track record with quality and reliability but it was all I could get in time. I took a gamble and lost and had a broken bike sitting at home all weekend.

My trip was a shooting/riding weekend trip to Frenchville, PA...I still went for the shooting expecting to be sitting in the cabin cleaning guns with my tears while my 5 buddies were out riding, but luckily a very nice gentlemen let me ride his WR250 all weekend. It was a blast and I liked the light nimble feeling of a 250 on the trails and jumps. Might have to make the switch...I'd miss the power but picking up and kicking over that little 250 all day was awfully nice...

Anyways I'd really like to do it right this time. RickyStator I sent you a PM regarding the re-coiling of my factory unit. Hopefully the shipping rate isn't too terrible! Thanks all -M
