stevepeanut Posted June 19, 2010 Report Posted June 19, 2010 any idea what would cause an engine to lock? I have been messing around with the little monkey bike, it has no spark, so been sat with the plug against the engine, prodding on the kick start and also using the electric start. All of a sudden the engine has appeared to go solid, I cant move the kick starter and the electric start wont spin. It hasnt been running so cant see why anything would have failed. I aint got a clue, any ideas?
bortaf Posted June 19, 2010 Report Posted June 19, 2010 does it have fuel getting in there? otherwise it'l friction seize cos the fuel oil lubes it ? sorry not really looked at a bike in over 20 years

Tom Posted June 19, 2010 Report Posted June 19, 2010 where you kicking it or electric starting it when it locked? Starter could be siezed?
stevepeanut Posted June 19, 2010 Author Report Posted June 19, 2010 I was kicking it, done it over and over, then one time, with the kickstarter at the top it wouldnt go down, and the electric start wouldnt spin
caprinerd Posted June 19, 2010 Report Posted June 19, 2010 could be something stupid like the wrong plug had a ped in the other day guy changed the plug and then the engine locked up he put the wrong plug in and it made contact with the piston as it was to long

caprinerd Posted June 19, 2010 Report Posted June 19, 2010 then it could be that the piston has locked and it will need a new piston and pot aint expensive

stevepeanut Posted June 20, 2010 Author Report Posted June 20, 2010 I put a chain back on the bike, and rolled it back a touch and the engine is moving again, although now it appears to be stuck in gear

Stu_B Posted June 21, 2010 Report Posted June 21, 2010 I had an old field bike with a slack chain, it punched through the gear casing and locked the bike solid.
DrewMK2 Posted June 22, 2010 Report Posted June 22, 2010 yry rocking the bike forward and backwards while selecting gear, bikes do this alot. if you have a stand rock the back wheel and select gear. the dogs in the gearbox mite be hitting eachother. worth a go. also if its been stood for a while the clutch plated will take some freeing off so may seam stuck in gear if this is the case. good luck pal
stevepeanut Posted June 23, 2010 Author Report Posted June 23, 2010 I've had enough I am going to sell it
