New hypothesis

[Sully60]

Hey sully..it's got nine and a half thousand ks on it so i assumed that it doesn't require a rebuild right now. Yes it won't fire up even when hot , i just keep kicking and it just kept dying and another yes to her requiring a great velocity to get it push started.....do you have a theory..i smell a theory lol The not starting coincided with my gearbox being a little funny.

Well the gearbox thing being funny is strange, does it do stand up or is it more of a sitcom type of comedian?
That doesn't factor into my theory at all but the other stuff you describe does.

9500k's isn't a whole lot if that is the actual mileage but I would be thinking that your engine is low on compression.
This could be due to the ring(s) being stuck/seized in it's groove (but then the probably wouldn't go at all) , worn ring(s) or broken,stuck, poked reed petals.

The crash start thing is what sparks my theory, most engines in a worn state will still work ok with a few revs but are pretty hard to start and are hopeless of the bottom.

Just another theory Drider, probably not one you want to comtemplate from the repair point of view but maybe worth investigating.

Worn rings or bore isn't usually erratic., it'll always be ahrd to start. This is different because sometimes it starts easily other times it is a pig.

Worn seals, it wouldn't idle.

My guess is water in the fuel. Or something tricksy like a failing coil or pulsar coil (or ECU I guess). But thoses engines are usually pretty tough. And if the meths in the tank helps that points to fuel.

Next thing I'd suggest is drain the carb, there should be a drain screw on the bottom.

OOPS: I just noticed something . 9500km ? So, is it still under warranty ? If so, just buzz it back to the dealer - his problem.

lol i think it's warranty expired eight years ago , cool so at the mo it looks like a fuel problem. Basically turn fuel off, drain the carbs and then see what happens. UNfortunately that one time i topped up at mobil was the last time i topped up so the um tank has lots of mobil crappy fuel in it. I didn't know fuel could do that?? As for it being maybe a coil problem? Easy to check the status of the coil? Far out lol talk bout two stroke maintenance 101....but i luvs her lol

Sorry, missed that bit.
Peeeeeooooow

Thanks for the help tho sully always good to eliminate the options aye. Stupid mobil *until the mobil theory is discoutned i will curse them.....curses!* petrol.

Wooh - wait up. Eight years ? I assumed from 16000km that it was fairly newish. 8 years may add some possibilities.

or they disconnected the speedo cable, or simply wound it back. you never know with bikes unless it's digital, and even then......

its possible that the carb keeps filling the bowl to full
this will cause hard to start and when is going will then die at idle by its self
my old 4 stroke trail used to do this '
so i suspect this is the case
the symptoms sound the same
and your saying it seems to be a fuel problem

maybe the carb needs a clean and to be reset
if theres a small hose from the carb heading to ground see if theres any fuel around the end of it or dripping to the ground
if there is id guess the carb bowl is getting to full

ok, i suppose someone should mention the thread "moved" to here http://www.kiwibiker.co.nz/forums/sh....php?p=1393951

drained tank and carby, put decent fuel in, and it wouldn't fire... no spark it turns out
