I was riding home from work today i was gooing 140km/u and sudenly my engin bloked, my rear tyre slipt 6-10m or so but than I regaind grip and my rear wheel started spinning again but the engin dies if i pull my clutsh lever

I think it is my piston 50% jamed in my silinder but thats just my idea

what do you guy's think of it?

 

[Old Painless]

Sounds nasty.

Does it run properly ?

the engin dies if i pull my clutsh lever

 

[Old Painless]

Okay sorry. Ill go back to the usual.

OMFG SEIZURE ITS FUXKED GET A NEW ENGINE !!!1 1!! ONE 1!!!1!!1!ELEVEN!!1111!!!!!!!

Does it die when you pulled the clutch in when you were riding it is what i mean and if so, does it run now.

 

[trajan]

the starter motor can move the piston up and down like normal but the engin just wont start im gona try a new sparkplug maybe that isn the caus of no combustion

 

[Gav2k]

piston and rings as a minimum, proberly need a new topend due to scoring tho.

 

[Old Painless]

Take the exhaust off and have a look through the exhaust port, you will see either a bright sparkly piston or a smeared mess.

 

[trajan]

I lookt at the piston a few min ago it looks like how a piston is suposed to look like (strangly enough) i tryd to push is down and is went down like normal what i did see is that the piston is dry so my guess is there isnt geting any fuel inside the engin i tryd to start is for 30 min or so

 

[Old Painless]

Did you look at the top of the piston or through the exhaust port ?

You need to see the side of the piston.

 

[trajan]

yup i looked thrue the exhaust hole and the sparkplug hole

the cilinder looks used but shiny

I have put it in first gear and ran my ass of and it started like normal today. i'm gona clean my carb wile im at it its greasy and full of dirt so i think the filter is jamed

 

[Old Painless]

I would concider a compression test to check if anything nasty has occured.

You might want to look at cleaning the fuel filter in the carb, they get a surprising amount of bits in there after a few years.

Grab come carb cleaner and give the jets a good soaking.

Sounds like you might just have been lucky.

If it has seized i would expect yout little end bearing is shot, that will make the piston start to slap and will wear it out very quickly.

Keep a very close eye on your bike for a few months.

 

[trajan]

ok ill do that thanks for the help

 

[Bananas]

How does it sound? If either the little end or crank bearing has gone it will probably sound much noiser than before.

Whatever caused it, I'd be super careful of how I'd ride it over the next couple of days. Just think of the consequences of that lock up if you'd have been cranked over in a bend at speed!
