PROBLEM STARTING 1998 KX 500

<< < (2/2)

stock500:
My bike is a beast to start, but if I tip it over until fuel leaks out, stand it back up kick it slow and soft 3 times, make sure the kickstart is at top dead center, and give her hell it never takes more than 2 kicks.  If I turn the fuel on and start kicking I will be there for a while.  The K5 likes a big drink to start.

Danger4u2:
When you remove the float bowl nut keep it upright.  Check for debris in it.  You might have "stuff" in your gas tank.  There is a screen on the petcock inside the tank. It might have a hole.  I had a customer come in as I was typing this.  I noticed you made a post since then.
Any junk in the bowl nut?  Did it flow when you opened the petcock?
I find the K5 hard to kick but not hard to start.  Go with the easy stuff first.  Fresh gas proper mix, clean air filter,  fresh plug at proper gap.....  So If the compression, timing, spark, fuel oil mix, fuel/air mix is correct it should start.

Platypus:
I could be wrong but I thought lean seizure was a possiblity if you run the motor out of gas? 

hughes:
Start by changing the spark plug.

hey fellows,got it going,i did put a new plug in but i dont think the old plug was fouled out.all i did was take the choke off and it started 3 kicks with my left foot! of course on a stand with my right foot on a stool on the right side to support the massive kick.(my right foot bottom has a swollen knot on it and pretty sore even though i wore my boots)man this 500 have some serious compression.i will never run the carb dry again(big mistake!)i called a well known bike shop and asked about a decompression valve and they said they never heard of one on a 2 stroke,they said the 4 strokes have them.these would be great with a decompression valve but i guess if your bike is jetted well and runs fine it should take no more than 3 kicks cold.
