Bike won't start!!!!! Help

9 posts in this topic

I have fitted a new camchain and tensioner to my 1994 XR600R and now I cannot get my bike to start. I have checked and double checked the following and they are all ok: cam timing is bang on, valve clearances are bang on, no airbox leaks, I have a good spark, I have tryed 3 different plugs and they all seem to be getting wet, I have stripped the carb and checked it and it is ok.

Does anyone have any idea what it might be?????

It is also a fresh engine with less than 500 miles on it before I changed the cam chain.

May sound REALLY simple.... but make sure the GAS is on, and there is enough in the tank, otherwise go to reserve. Sounds lame... but lots of us have done it.

compression?

fresh gas?

try spraying some starter fluid in it and see if it will rumble...

it could be anything from a faulty plug cap to a plugged jet in the carb. did you try bump starting it? you sure the carb dont have varnish in it?

Try turning the idle knob up 3/4 of a turn. If the bike fires you can easily turn the knob back to it's orignal position. Thats why the knob is so big so you can turn it with gloves on. If thats a no go put some gas in the cylinder and kick it over then add a little more. I had the same problem that you are having and i found out that my choke lever wasn't turning the choke on do to a missing spring so make sure your lever turns the choke on. If you get the bike running turn the choke on full, if the bike begings to sputter then thats good, if not your going to have to order a new spring.

Thanks guys, I have tried all those things and still no luck. Is it possible to put the collar for the pickup on the wrong spline on the crankshaft? It's the only other thing I can think of.

What should the float level be and how do i measure it? If it is that it is weird because it always used to start easily before I changed the chain.

Well problem solved, the pickup collar was on 1/3 of a turn out, so was firing at the wrong time!!!!!

Thanks for all your help guys.
