Hello
previously had a no spark (thanks forum) and have progressed to a no start .
I have not had this bike running. Motor comes from a 89 kick stark. Motor has a newish piston and top end. (previous owner claims very low hours put on since rebuild}.
Bike was stripped down and combined with my old 85 xt600 to get one solid bike.
Ok I can't get it started and its a beast to kick over.
I have not done a compression test yet but based on the receipts, old piston and the kick start resistance I believe the compression should be good for it to start and break my leg.
I have spark
carb is getting fuel at least to float bowl
carb has been cleaned with new o rings and gaskets. A/F is at 2 turns out
kicked for awhile with choke out no throttle -nothing
air filter removed short spray starter fluid- nothing
kicked a bunch more- nothing
rolled down steep hill a bunch of times - one or twice it tried to turn over it seemed. lights brightened looked promising but nothing more. Got fed up and went home.

Plug was dry. (pulled before the hill jump)
Plug is new and gapped
I had the air filter out. (maybe too lean to start?)
no backfire no popping
no gas smell
kill switch on run
feels like its not getting fuel but I was hoping the stater fluid would of at least kick something over.

Advice please
Greg

try to put a squirt of gas directly into the cylinder through the spark plug hole. I always mix some 2 cycle oil(40:1 ratio) in this gas to give some lube to the cylinder. Maybe 1 teaspoon of gas/oil mix at a time. If the spark is right it should start a bit. That will tell you if it's carb or cylinder issue. Also turn the idle screw clockwise(raise idle) about a 1/3 to 1/2 turn. You can readjust later once bike is running.

For my bike starting I need to, keep the ignition off, full choke, no throttle , kick it over three or four times( not hard just steady to draw fuel). The return kicker to the top, turn ignition on and one almighty kick. If no start, return kick lever to top and repeat hard kick till it starts.I can never give it any throttle while starting.

Thanks for advice, but still nothing
What I have done is poured in a little gas straight to cylinder.
Have sprayed started into carb inlet
I have a spark tester hooked up for testing not for starting attempts. It shows spark, how much i'm not sure but its there and even on an easy kick.
I have never had this motor running as it is new to bike. I know it has a newish wiseco 4797m09700 piston in there. I don't know if this is making it so hard to kick as I don't remember my 85 xt this hard. I can just stand up on it.
I know i might not have the sequence right yet for the decompression release but this is nuts how hard it is to turn over.
I will pull carb again and give a look, it was thoroughly cleaned with new o rings and gasket.
I have gas in the float bowls.
will check float height again
I have another ignition coil I can try as well
When I take spark plug out after trying to start it has a faint gas smell
So many hours in her all ready

Put a couple good squirts of motor oil down the spark plug hole and kick it over slowly a couple times to make sure the cylinder walls are good and coated, then just squirt of gas, put plug back in, slowly push the kick lever down till it hits "the wall". push just hard enough till it passes that spot, get past it barely. Release the lever to allow it to return fully. Now kick it like your trying to shove the lever 2 feet into the ground. If no fire then you have something other than fuel issues. It may not completey start but it should fire and sputter for a bit. And remember, no throttle whatsoever when doing this. After this you may try repeating this whole setup only give it 1/16 of a turn of throttle, just to try.

I will never use starting fluid on gas motors !

I kind of suspect it is cdi . Try tapping it several times with a screwdriver handle.

I checked the ignition coil for power. Now i'm confused. Battery is at 11.7 volts. multimeter with black lead to batt neg, red lead to coil (orange) from CDI side I get no power.
Now with red lead to coil and black lead to batt POSITIVE i get 11.7 volts.
So i shut ignition off and I get 11.7volts as i am making a circuit?
So switch black lead to ignition coil (orange) CDI side, red lead to batt neg and -11.7volts.

Confused, shouldn't i get black lead to batt neg and red lead to coil for power? and wouldn't it be slightly less then just checking battery?

But I am getting spark

I have another cdi and coil. i'll swap each out on their own. Both were from my old running 85 xt but that was now about a dozen years ago.

Plug is new
gas is fresh

THANKS for the advice and help

You can charge battery or buy a new if its not taking charge, 11,7 is to low.
