Check your intake boot doesnt have a crack in it. If it does, it wont be getting any fuel!

Goutman, when you say good spark, I take it you mean a nice fat blue one? Is the plug ever wet when you take it out to check it?
Urgh, hopefully they didnt just put it together with that crap mechanics use on sheared flywheels to hold em then flog it off

Local shop did that to my wr400 even with the thread rooted on the shaft that holds the flywheel on, ended up replacing the crankshaft my self as once they got it going turned out the bike needed the big end done anyway

They are bloody hard to start. I had the same problem, took me a good 6 months to get the nack of starting it. If you do it wrong 1 or 2 times, u will probably flood the carbie, then ahve to wait 10 mins before u try again, u got to get it in the first couple of shots. put the stand down on the bike and stand on the pegs to start it to get more kicking room. Kick it over in rapid succession about 4 or 5 times. I found the rapid succession kicking very successful before i got the proper nack down.

In regards to the de-comp, before u try to start it, pull in the de-comp and kick it over bout 5 times, then turn it over till u get to the friction point, pull de-comp slightly till u get to the next friction point, release, let the kicker come to the top and give it a big kick. If it does not start, kick it over about 5 times in rapid succession. If it still does not start, wait 10 mins and try again

I dont use the throttle to help start it as they have a mechanical fuel pump, and use the decomp lever. The method in which i use to start it goes like this... fuels on, chokes out, kick down till i get some resistance, engage decomp lever, kick down a further poofteenth, release lever and give it a boot. It doesnt even give a hint of wanting to fire. The only thing i have done since purchasing the bike is add a tank of premium fuel and a new plug.... what are your thoughts?
I have a wr 426 01 model Once it has started once you must use hot start.
It took me a long time to start bike when i 1st got it. but now is is easy hot or cold. if does not start 1st or second kick with choke on it is prohably fueling up. Use hot start and even if you throttle it it will still start. Also if you have been kicking it with choke turn fuel tap off to stop it fueling up.
I am in windsor if you can travel i will give you a hand to learn to start it.
Once you learn they are dead easy I'm sure there is nothing wrong with your bike post a reply if you need some help

When set up well with a rider that knows what they are doing they start first kick every time, hot or cold. Most of the e start boys were still winding whilst the 426 was thumping in the carpark

A mate has one and he can start it in thongs(the ones on ya feet!) so once you have the knack its pretty easy.

once you get that resistance point and you pull in the decomp lever and push it that poofteenth and release the decomp lever bring the kickstarter all the way back up then your getting a full kick out of it

we got this running yesterday, took it for a belt down the street and it ran beautifully. Then when Goutman tried to start it up again, it wouldn't. Did the same thing a couple of hours later after we let it cool (started, turned off and then wouldn't start up again).

Im not sure if goutman was using the hot start to restart it - the previous owner said he never had to use it...
