Dlatch Posted May 19, 2014 Report Share Posted May 19, 2014 check the vid to hear the rattle and vibration it felt kind of like a engine mount had come or something was out of balance, i knew the stator and flywheel was rusty when i got the banshee but could not find where the water was getting in so i was strongly suspecting this area as the culprit. hmm that looks odd do you think it is still balanced ok? lol Stripped it all out now and lucky for me i have a spare engine to supply a new flywheel, The flywheel nut was still tight but there was some up and down play so i and pretty certain that is causing the problem now i have cleaned it all up the crank has no play in or out or up and down with the fly wheel removed so looks promising. what do you guys suggest i do with the spare flywheel? i hear i should reseat the flywheel on to the taper using grind paste is this correct?

2004LEBanshee Posted May 20, 2014 Report Share Posted May 20, 2014 Yes lap it with valve gringing compound. Impact it on and use blue locktite on nut. Ugly Quote Link to comment Share on other sites More sharing options...
Dlatch Posted May 20, 2014 Author Report Share Posted May 20, 2014 still impressed it ran as well as it did, also think i have found the source of the water getting in, the grommet where the stator wires pass through the engine case has a split in it. my spare one looks good but i think i will also seal around the wires inside the grommet with sealant. ordered some grinding paste so i can seat the spare flywheel. just debating on doing the ignition advance mod while i am at it Quote Link to comment Share on other sites More sharing options...
2004LEBanshee Posted May 20, 2014 Report Share Posted May 20, 2014 I would. + 4 timing bump is a cheap mod you can feel. You could just get grinding paste at any autozone advanced ect. You could also just grind the holes on a stoc plate 4 mm and turn the plate to get the +4. Free mod and works. 1 Quote Link to comment Share on other sites More sharing options...
blowit Posted May 23, 2014 Report Share Posted May 23, 2014 I would highly recommend you indicate the mounted flywheel axially and radially to check for runout. It appears the other one was welding itself which can be caused by excessive out of balance or not mounted correctly. I had one in here some time ago from a member that was fighting with broken cranks from this issue. Worth checking!

Dlatch Posted May 24, 2014 Author Report Share Posted May 24, 2014 Tried the spare stator setup today and got the flywheel nicely seated all ok started up second kick still has the exact same rpm related rattle/vibration i am thinking this engine needs a strip down as something ain't right and its best to stop using it before it does major damage so i will get my spare engine sorted and have a look at this one later Quote Link to comment Share on other sites More sharing options...
SOUTHTHIRTY Posted May 24, 2014 Report Share Posted May 24, 2014 Spun crank maybe 1 Quote Link to comment Share on other sites More sharing options...
blowit Posted May 25, 2014 Report Share Posted May 25, 2014 And you indicated the flywheel in? Quote Link to comment Share on other sites More sharing options...
Dlatch Posted May 25, 2014 Author Report Share Posted May 25, 2014 And you indicated the flywheel in? yes i seated the spare flywheel in with fine grinding paste, but the out of balance type vibration is the same but i think the rattle may be less as the flywheel is not hitting the stator coils. still runs perfect with good compression Quote Link to comment Share on other sites More sharing options...
blowit Posted May 25, 2014 Report Share Posted May 25, 2014 Indicating the flywheel has nothing to do with lapping the seating surfaces. Quote Link to comment Share on other sites More sharing options...
camatv Posted May 25, 2014 Report Share Posted May 25, 2014 i think the source of the water getting in is the huge mud holes and lakes your riding in. its a sport bike not a mud racer.. yank the motor and check for piston skirts still attached / and, or hydrolocked crankshaft and or phased out crank from hydro lock ok just watched the video. check all your motor mounts also. almost sounds like looks like a exhuast spring rattleing against the pipes. but kinda hard to tell in the vid. motor has a nice decell shake to it! 2 Quote Link to comment Share on other sites More sharing options...
VoOK Posted May 25, 2014 Report Share Posted May 25, 2014 I had a sound like that before. Turned out being the exhaust spring. Quote Link to comment Share on other sites More sharing options...
Dlatch Posted May 25, 2014 Author Report Share Posted May 25, 2014 spare engine is dropped off for a rebuild old engine is out took me just under 2hrs not bad for my first time on the banshee now just gotta jet wash all the crap off it haha All the engine mounts are perfect, suspect problem with it is as said by others the crank has spun knocking it slightly out of phase, when i get some spare cash i will have to get that engine rebuilt to a 4mil setup Quote Link to comment Share on other sites More sharing options...
Dlatch Posted May 25, 2014 Author Report Share Posted May 25, 2014 Camatv here in the UK we are really limited for places to ride so i pretty much only get to play on Motocross tracks and i am not really a mudplugger at all i even got ragged because of my mudflaps on here lol what i did discover today is how that water was getting in it was running down the stator wiring loom sleeve prob not helped by over zealous power washing by me and previous owners i will be sealing up all outer sleeving with silicone sealant on reassembly try and make this as water tight as possible Quote Link to comment Share on other sites More sharing options...
m671054 Posted May 25, 2014 Report Share Posted May 25, 2014 Just remember to remove stator cover and blow dry when done washing. You'll never seal it completely. 1 Quote Link to comment Share on other sites More sharing options...
