plasticookie Posted October 6, 2008 Report Posted October 6, 2008 (edited) So I bought a trinity stage 4 adj timing plate, had a hellacious time getting the holes to match up bc it was almost too big...put the flywheel back on and tightened it as much as possible(with a wrench), timed it by ear, and put the cover back on...I drove it around the yard for about 5min and everything was fine, then decided to take it down the rd and back 1 last time before putting it up. 1st everything was good, 2nd still good, 3rd i pulled up and rode a nice wheeley(probably my last) and about the time i sat her back down she backfired and thats all she wrote. After pushing it back to the garage I discovered that the flywheel had came loose and the key had also came out...the wheel looks ok, the key has marks on it, and the tips of the stator are slightly wore down and smell heavily of ozone...Does the key have to be in perfect condition to be used??? Why did the wheel come off??? Are my problems bigger??? Edited October 6, 2008 by plasticookie Quote

lowbuckracing Posted October 6, 2008 Report Posted October 6, 2008 I use lock tight and a lock washer,Then I use a impact to reasemble..Good luck..Also the key must be in great shape or dont use it.... :cool: Quote
akita8 Posted October 7, 2008 Report Posted October 7, 2008 Ditto on the red locktite and the impact gun. If the keyway id not buggered up too bad you can reuse it. I'd clean up the flywheel and reinstall to see if the stator is good. Quote
locogato11283 Posted October 7, 2008 Report Posted October 7, 2008 impact my friend. no need for loctite or anyting else. all you need is an impact and a good woodruff key. also, why did you time it by ear? the timing plate should have marks on it. line them up where the cases split with whatever timing you want.

sinisterboo Posted October 7, 2008 Report Posted October 7, 2008 I believe the key is only there for locating the flywheel, and the nut tightness takes the force. your prob was your nut wasnt tight (lol) and your key took all it could handle. also make sure to wipe the crank snout, and inside the hole in the flywheel with brake clean. grease and oil are bad. And can you take a pick of the stator? and did it eat your pick-up coil when the flywheel came loose? Quote
plasticookie Posted October 7, 2008 Author Report Posted October 7, 2008 (edited) Ill try and take a pic when I get home...i think the pick-up coil is ok, the flywheel didnt come completely off...I know it has marks,but i gave it about 1/4 to 1/8 throttle and set the timing by ear when i heard it open up...i was goin to use a impact but couldnt find and the guy at the yamaha shop said just to tighten it as much as i could :shoothead: Edited October 7, 2008 by plasticookie Quote
locogato11283 Posted October 7, 2008 Report Posted October 7, 2008 thats what you get for listening to the guy at the yamaha shop. Quote
05.Banshee.SE Posted October 7, 2008 Report Posted October 7, 2008 thats what you get for listening to the guy at the yamaha shop. Hahahaa...so true. I bet he'll even offer to fix it for you....for about $34,536,578 and some change. Quote
sinisterboo Posted October 7, 2008 Report Posted October 7, 2008 you dont "time" a banshee. Go to the vids section and watch HQ member Magz vidoe on installing a timing plate. It explains everything! Quote
plasticookie Posted October 8, 2008 Author Report Posted October 8, 2008 Ive done looked at it a few times, but thanx...looks like the key is to gummed up and the groove where it inserts into the flywheel is also pinched on the edges and the stator is dunzo and and and etc.... Quote
2strokespirit Posted October 8, 2008 Report Posted October 8, 2008 Locktite means nothing if the nut wasn't tightened enough.. That was your problem... Get a new key.. Quote
plasticookie Posted October 8, 2008 Author Report Posted October 8, 2008 I know u guys probably will probably think im a dumb arrogant sob, but I sanded the key and flywheel groove until they were both pretty smooth and put the flywheel back on to see if the stator still worked and amazingly it fired up on the first kick and ran like new. So I think im gonna go against popular demand and just impact the bolt back on with some temporary locktite and leave it at that. Quote
sinisterboo Posted October 9, 2008 Report Posted October 9, 2008 (edited) hey, whatever gets you back on your shee (as long as its safe, LOL) is fine by me! Edited October 9, 2008 by sinisterboo Quote
