I have worked about 4 weeks on my Griz600 and have burnt 2 CDIs up ! I added a wire harness and stator and It starts but runs erratically like spark timing is off ! So I would like to try another CDI but I don’t want to Pay an arm n leg ! Anybody have one ? Thanks

I have been trying to get my Griz600 running right for 3 weeks ! Grandsons used it and it quit running , no spark ! New stator etc and started but ran terrible ! Found a burnt capacitor on cdi . Installed used cdi and burnt it also but ran same as other cdi . Came to conclusion wire harness had short so stripped it and found some bad spots fixed and another cdi ran terrible again ! Bought another harness and same rough running ! Checked spark timing with light (put tdc mark on case and on pull start hub) and when it starts timing right on but will jump 25+° retard ! When timing is on tdc marks it has no power ! The stator is new but I am wondering if the pickup coil is triggering incorrectly ? Also had top end apart when I first started having trouble and although rings were good I installed new rings . Also new timing chain and check the valves , they were good also . It kind of seems to boil down to the last stator I installed new ? I have done trouble shooting on quite a few cars , trucks , dirt bikes and ATVs but this is frustrating me ! Just wondering if anyone has any ideas ? Carb was new last yr and I checked it ! I

IMG_4272.MOV Originally had my griz600 stop running and then wouldn’t start ! After testing all coils , valve lash , compression (115psi) and all tested ok I bought a used cdi . After cdi install it still wouldn’t start (no spark) ! So even though the stator , pulse/trigger and charge coils check within good range I decided to switch the stator etc ! It started but It is very unresponsive on throttle and acts like it is running in 2 Different spark timing ! With slight throttle it will take off good but instantly go into a very different running mode with no power like timing very retarded but it will switch back to running good for short period then bad again ! Since I replaced the stator and it started I then decided to install the cdi I replaced and it did the same thing ! Also I noticed the Used cdi I Took off had a capacitor that had swelled and extruded from the back of the cdi . I had always heard and I believed that when these CDIs go bad they machine will quit and will not run . Is that true ? I also checked the cam/valve timing and its ok ! Checked with timing light and it does fluctuate on idle ! I am thinking I have 2 bad CDIs . I also switched the trigger Coil wires and would not start then . Man , this thing ran good before and I am confused ! Video below may help !

I recently got a 98 warrior 350 that 'needed the carb adjusted' but the reality is it has no spark. I have a new spark plug, plug wire, ignition coil, battery, and cdi box. I checked continuity and took apart and inspected the starter/kill/light switch on the handle bar, and it all looks brand new and checked out. The key switch seems to be working properly, as when off, nothing works, but when switched on, lights and electric starter button work. It turns over fine, and as I just stated, all the lights work. I took all the plastics off and traced all the wires, and only one had a small cut in it, but it was only through the rubber sheathing, not the wire itself (the blue one coming from the stator). I cleaned some grounds, made sure both relays work, and still nothing. I pulled the stator cover and looked at the stator itself, and it looks great. No broken wires or connectors or anything. Still, no spark. I'm at a loss. Where do I go next? Any help is appreciated.

Hello everyone,
Im new here, this is my first post and Im trying to figure out how evrything works on this site so I please let me know if Im doing anything wrong.
I have a couple Yamaha's but this post is in regards to my 02 Grizzly 660, I have an electrical draw somewhere that is taking my new battery down rather quickly. I have tried to locate any short by checking each circuit but was not able to locate it that way. Im installing a battery cut off switch which brings me to my first question, dont these switches usually go on the Negative terminal?
My next question is, can anyone tell me if this year and model has any history of electrical shorts that might help me locate the culprit? Any help would be greatly appreciated!
Finally, Im looking forward to being a member of this site and hopefully helping others as well as learning some things myself, so greetings to all!
Best wishes to everyone!

Hello All,
I have a 1999 Yamaha Big Bear 350 4x4 trying to get fixed up so my grandson can go out in the woods with me.
We have owned it over 10 years. It got harder to start, until it finally would not. Replaced the carb. Right afterwards, it started and ran nicely, but after turning it off, would not restart. Tonight I used starting fluid and ran, then died. Adjusted the idle up a little, used more starting fluid and ran great. It idled about 15 minutes. Turned it off, and restarted. Ran it around the yard about 5 minutes. Turned it off, and would not restart.
Any ideas or suggestions would be greatly appreciated!
Thank you.

I’m just wondering what year bike i got? it seems the vin has been rubbed off i got it from a auction here in Australia engine starts but seems has a dirty carb wont idle well
and also has a problem I put it in gear and makes a grinding noise but does not move it the neutral light goes out but then when I change gear it grinds more in the higher gears as well I’m guessing the differential is stuffed so wanting to buy new part for it will start the pull down next week
this is the first bike I have worked on used to dealing with cars
