We have an 06 that died on us. it ran fine all day then while it was idling it died. The startor wouldn't work so we pushed it off and it fired up for about a half a minute then died again. The fuse at the battery was blown so we replaced it but still nothing(battery was fully charged). I replaced the relay and still no starter and no spark. I disconected the switch and the kill button and checked for shorts, still nothing. I can use a jump wire and make the starter work but no fire and starter doesn't work with the button. I am not very well versed on electrical stuff but I have traced all the wires and checked for current as far as I can. I'm not sure what should be hot and what isn't. I know I have power to the CDI but not past it. Is there any home test you can do on electrical components to tell if they are working? I don't want to start shelling out money for components that are not broke to find the one that is. Has anyone else had this problem?

Same thing happened to me and it was a loose connection on the key's wires. You have to squeeze the hell out of them and duct tape them so they dont come apart again. I hope this helps.

I have bypassed the switch all together and same results. I think I am at a dead end on it.

Damn that sucks. You even tried the connectors under the tank? Those bastards always used to come loose on me.

TedLieb · 07-13-2008, 05:18 PM

I have unwrapped and traced all the wiring and connectors. It has to be some component that has failed. I didn't know if there was something common to fail on these that I could check. I'm not sure how to test the components on this bike (IE; which color wire should have power with switch on/off). We have out grown the bike and while I would like to sell it running, I would come out better parting it out. It has the GYTR exhaust and jet kit in the carb, BBR SP-5 front fork kit, Sano aluminum swing arm, crower cam and a host of other after market parts. It is a sweet bike running and this is the first problem we have ever had. I hate undoing all that work to just part it out.

That sucks... did you notice any better performance from uping the cam?

TedLieb · 07-14-2008, 04:04 PM

The cam gave it more top end and especially mid range. I did it in combo with the pipe and the jet kit so I'm not sure what helped most. It is more difficult to tune the carb than the CRF 50 though. I had to play with the jetting a lot and then it is more temperamental to climate change. We ran the Power roll cam and high compression piston in the Honda, but the Yamaha was still faster. He would pull the hole shot over the Hondas every time.

One more thing on the cam, it is much more difficult to install than a Honda. You have to pull the rocker arms, press out the pins and all the fun stuff.

tt-r420 · 07-16-2008, 07:23 AM

Have you checked the owners manual for testing specs on electrical components?

TedLieb · 07-18-2008, 04:11 PM

Yes. All I have is the manuel that comes with the bike and it doesn't give any specific information.
