until you get it apart its really impossible to tell you what it will cost, it will depend if the barrell is ok, it may be a crank seizure or a piston seizure,

update: bottom of the conrod is ceased.... the head was almost finger tight :(
cylinder , piston , main bearings and top bearing is good.

could not take flywheel out , was scared to crack.

what is the options?

thanx a lot.

[glukasil]

tried to locate new conrod kit in new zealand for the engine.......... 350 .... wtf?

is there real need to buy it or it is possible to get a replacement bottom bearing?

how much is to split cases , crank , replace bearing/conrod and put it all back ?

thanx a lot.

Sounds to me like you dropped your oily rag when out riding,
Very bad thing to do that, causes all sorts of things to go pop
When you get it fixed and running again.
Make sure you have a good quality oily rag with you at all times

Usually when I want to cease my engine I turn the ignition key off. Try that next time you want to cease it. Failing that, there is always the kill switch.

um.
if you're handy: buy replacement motor and drop it in.
highly unlikely a 50cc is worth replacing parts in (unless you REALLY love it. (or it's in a chainsaw :D))
if you're not handy. put it on TM and buy a new one.
or sell it to me.

five bucks and a bag of chips.

seems to me trolling made its way to kiwibiker...... :(

found a good guy to do crank but there are2 problems. first find a conrod kit and second to take flywheel out.

it needs a special puller looks like a 18 mm wide bolt with a hole in the middle for a smaller bolt.... does anyone have one?

thanx a lot.

Some witty road bike riders, guess all that scary riding they do leaves them short on excitement so they have to talk crap on here.

eBay might be good for the Conrod, but be heavy for freight from USA I bet, rockymountainatv have a good selection of parts and use dhl ( best couriers to Asia bar none ).

looked at a transplant engine......chinese , 4 speed , 9.5 horsies........need to adjust frame so :)

and just when we all thought it could not get any worse:facepalm:

Bottom end main bearings can be bought over the counter from any reputable bearing supplier, a conrod kit you can either go genuine or after market eg hot rods, wiesco . You'll need a engine gasket set which should include the engine oil seals cheapest I've found is Ebay either USA or UK way cheaper than here , just supply your engine and frame numbers to make sure it will fit.
Best to fit a new piston kit while its apart that way you know it will run for a few more years with out being touched.
Best of luck price it all up before starting to see if it's not a hole you'll be pouring money into with little return.

to ktm84mxc

found conrod kit and piston kit with gaskets.
conrod kit is hotrod and
pistod kit is KDF... is it any good?

thanx a lot

[ktm84mxc]

Happy to help, haven't heard of KDF before , just do a google search on them to be sure. I prefer a known brand or genuine just for peace of mind.

[glukasil]

y mistake. it is for kdf / ktm / lem..........i thought it was a brand name.
was told it is made in taiwan. comes with gaskets and rings...........dont have much choice anyway....
