Havent started the bike since rebuild. I already cleaned the carbs new fuel lines and all of that. Gets plenty of spark at wires didn't pull plugs out yet. Any ideas?

 

What kind of rebuild was it?

 

A complete rebuild minus the electrical. But I had gotten the bike started after replacing the ecu and some fuses off a parts bike.

 

just cause this happend to a freind of mine, is the gas on? does it turn over?

 

Yea gas was on turned over fine was just electrical issue I guess like I said I swaped out the ecu from a parts bike and change some fuses and it started right up

 

Spark
ignition (fuel)
compression
Exhaust

The process of an internal combustion engine.

If it is not any of those than you have an electrical problem.
sounds electric since you had it going then it suddenly did not want to fire.

 

air
fuel
correctly timed spark
compression

 

well, if you want to be that way. The book lists this order:
1. Intake
2.Compression
3. power (spark)
4. Exhaust

FOUR STROKE ENGINE PRINCIPLES

 

no fuel?

intake sounds like "air"
