Engine Problems

This morning I unloaded my bike to ride. I love in Ohio and the temp was fairly cold. The bike started and idled for approximately ten minutes. During which I bundled up for a day of riding. When I went back to the bike, it had stalled. I kicked and kicked an no luck. I pulled the plugs and they were both soaking wet. I dried them off and put them back in the bike. The same story of kicking and no running. I had a friend with me and we tried to pull the bike to see if it would run. No luck either. Lastly, I pulled the right side plug and rested it on the cylinder to check for spark. No luck. I would appreciate any help with this problem.

yes it should fix the problem of no spark. if the plugs are fouled pretty bad then you might have very little to no spark at all if you do have very little spark it might not be hot enough to ignite the fuel, but it sounds to me that your plugs are shot. replace the plugs, pull the choke, give it a couple kicks, and ride like hell.

Aussie is right. I thought the same thing. Book is just wrong. I had a no spark problem with mine and basicaly replaced every single component and fabricated a new harness to fix it. It ended up being a bad stator that tested good. Let me know if I can help.

Hey boys-

 

Thanks for the great responses. I really appreciate the feedback. After setting my piece of shit Clymer manual on fire I took my coil to the local Yamaha dealer and their service department tested it for me. It tested good. The next step I took was to test my stator and found it to be bad according to the pile of black ashes (Clymer manual). Does anyone know what the readings should be when checking the resistence of the stator? Please let me know.

 

Thanks,

When mine crashed I bought the Ricky Stators unit. It came with an adjustable timing plate and it worked great. The price was 125$ which is a fabulous deal compared to what the manufacturer wants. The wattage is for the lighting only. Your CDI box controls what your coil does. The Ricky Stators unit works awesome. As for the specs you asked about. Yellow wire to black wire should be .26 to .38 ohms

 

White/red to white/green should be 94 to 140 ohms

Sorry anyways the red wire to green wire should be 13.7 to 20.5 ohms. Just for GP you should know that when mine crapped out my red to green reading was at 20.6. That is a small amount but I guess that made the difference. So when you take your measurements you need to zero your leads first. Also The black wire is really a ground and it is attached to the stator with a clip at the end that punctures the insulation of the wire and is screwed to the staor frame. You may want to check that your engine is electrically connected to that black wire by ohming from the black wire to the spark plug base that is screwed in tight to the head. There are some other things to check also so if this gets you now where say so. Good luck
