06Shee Posted January 26, 2009 Report Posted January 26, 2009 Hey guys, I was riding my bike on 6th gear ( full throttle ) for like 3sec then the bike starting giving some sounds and then it felt like the bike was braking (as if some1 hit the front brakes hard ) and the bike turned off. So when I tried to start it, the kick start wouldn't kick. It was locked it wouldn't move down. I then pushed it to my house, and tried to kick it, the kick starter now works, but when i kick it, it just feels dead, and you dont hear the noise of the spinning flywheel or anything, it just feels dead. Thanks Quote
BansheeRider87 Posted January 26, 2009 Report Posted January 26, 2009 Hmm sounds like youll be rebuilding Quote
BansheeRider87 Posted January 26, 2009 Report Posted January 26, 2009 And i wouldnt keep trying to kick it over. might cause more harm then good Quote
2001Stroker Posted January 26, 2009 Report Posted January 26, 2009 Sounds like it might have leaned out on you. Probably time for a teardown. :ermm: Quote
Guest utleybanshee Posted January 26, 2009 Report Posted January 26, 2009 Sounds like it might have leaned out on you. Probably time for a teardown. :ermm: yea same thang happen to me.. busted water hose didn't know and ran it hot.. locked up and wouldn't kick right then...but after the pistons cool down they will move in the cylinder but u have no compression..

blaster2006 Posted January 26, 2009 Report Posted January 26, 2009 Sounds like it might have leaned out on you. Probably time for a teardown. :ermm: its not running lean.. let me start by saying im a really good friend of 06shee, i know him irl, (but dont live in the same country anymore). his sparkplugs are perfect the insulator and electrode seem perfect, a tanned color. i was thinking it could be his 4mm crank that broke? isnt it true that the bigger the stroke, the easier it breaks at higher RMP's, since he was going at full throttle high rpm, maybe the crank broke, and explains why it feels "dead" when he kicks it over IMO. and i know that hes getting a new set of cylinders like the cheetah cub kit or something, if his crank is broken he can just get that crazy kit on ebay which comes with a new 4mm crank, insane 72mm jugs (pre-ported) with pistons for it etc and domes, a full kit. if its his pistons or it blew up, he can just go for the FAST kit that comes with jugs and pistons only. if its a problem with the crank/pistons/jugs etc it wont be that bigga deal since he was planning on a new set anyway, right 06shee?

swrbansheeboy Posted January 27, 2009 Report Posted January 27, 2009 (edited) sounds like you leaned it out and siezed the top end but hey, blaster says your plugs are great so that couldnt be what happend... pull the head and i'd bet you find a piston that looks very grey and melted on the exhaust side if not both of them.... and just because the bottles full doesnt mean the impellers still intact and eveythings flowing like it should be... if the bottles over full then i could have been puking the coolant back to the bottle because it was overheating...

regalrocket Posted January 27, 2009 Report Posted January 27, 2009 Pull the tank, pull the plugs, get flashlight and look at carnage. You burned it down, totally classic. They always run the best ever, 2 seconds before they stop running completely. Quote

swrbansheeboy Posted February 1, 2009 Report Posted February 1, 2009 if you mean broken crank as in broken in half do this, pull the stator cover off and put the bike in gear. kick it over and if the bike tries to lurch forward and the flywheel turns at the same time then chances are the crank is still intact. now if the top end leaned out as bad as it sounds it probably took out a lower rod bearing, pull the tank, plugs and stator cover. now rock the flywheel back and forth and observe how much the pistons move, if it smoked a rod bearing you will be able to see one piston(maybe two) that doesnt move when you rock the flywheel back and forth. it's usualy accompanied by a klunking sound from the bottom end where the rod is slapping around because it's spit the needle bearings...
