Drz400 starts idles and dies with throttle (only works with choke off)

After taking apart side case here is what I found. 3 of the bolts holding the flywheel down had sheared off. And it looks like it scratched up the flywheel a little bit but it’s not bad enough to have to replace is it? And the stator looks pretty damaged so I ordered a new one. 

Thanks

Also just wanted to add that 2 of the 3 that sheared off just spun right out easily by hand but the 3rd one lodged itself way down to the bottom of the hole. I was thinking to drill and extract it but then I’m guessing I will have to pulll the flywheel off to do so. Kind of stuck on what to do to remove that last bolt. I just bought 6 12.9 bolts to replace them but I can’t install until I get that last bolt out. It’s literally at the very bottom

You might try a left hand drill bit with some grease on the end to trap the shavings. It might just spin right out without having to disassemble the engine any further.

Yes, left hand drill bit. Centre punch the bolt, use lots of pressure, slow drill speed.

Ok well it ended up falling down thru and I can see it but can pull it out from under the flywheel and starter clutch so I bought a 38mm x 1.5 RH flywheel puller and I’m trying to take it off now but every time I try to tighten the upper part of the tool it rotates the flywheel, what should I do to keep it in place so I can tighten it enough to break free the flywheel? Do I gotta put it in gear or do I have to jam something in somewhere?

 

thanks

Never mind I was able to put an adjustable wrench on the puller and break it free, I pulled out the old screw and replaced them with 12.9 bolts and put thread lock on them. I going to put in the new stator now and see if she fires up! Fingers crossed that’s all it was!

Ok last thing I promise haha.. so I put the bike back together with the new stator and it fired right up! The thing is, it got super hot quick(like 10 seconds) and I started seeing some white smoke burn from the exhaust where it connects to the engine so I shut it off.. could this be from the bike laying over on its side the past 4 days? Like the oil and coolant was all over on one side? Because I only had the bike up right for maybe 5 mins before firing it up. Should I just let it sit up right for a few hours? I’m gonna check the coolant level once it cools down but I never had any over heating issues until this. I would like a response before I try starting it up again because I don’t want to blow a ring or do any damage to the engine. Thank you!! So happy it started but I’m a little worried about this.

Did you spill any oil / touch the exhaust with oily hands during your repairs? when I give my bike a good wash I usually give it a squirt down with some WD40.  It makes lots of white smoke when you start it after that.
