Cleaned the carbs(weren't really dirty but did anyway) replaced spark plugs definitely needed to be done but the bike still won't start check the battery and starter and they're both good even tried to give if a push start and pop it into gear but when I did that it turned over then died scratching my head here on what to do next might try roll starting it down a hill after that idk any suggestions guys???

 

Make sure you have fuel coming from the petcock, and fuel filter. I would also take a look at the fuel pump make sure that its working properly. Giving a squirt of carb or break clean will help get it to start.

Have you rechecked all vacuum lines, that the carbs are seated in tight?

 

Are the float bowls filling up? My fuel pump went out at 60,000 miles.

Take a plug out and crank the bike to verify that you have a good spark, then spray ether through the carbs and get it fired up!

 

Same thing used to happen to me.

I would go through everything again and see if anything is loose.
Spray some carb cleaner down the air inlets on each carb, theres about 4 little holes that get dirty. Just pop the airbox off and they are right there.
- Also, try closing the choke and starting it.
- Check the petcock, and also pull off the fuel pump and see how your contacts are.

 

ok thanks i'll try thoses today but my bike has less then 9000 miles on it and fuel does come threw the petcock and everything was tight when i checked but ill go over it again

 

Sorry for the late responds but the fuel pump is in working conditions but the fuel filter needs to be replaced and can anyone tell me what would cause the bike to back fire

 

Plug wires on the wrong plugs could cause backfiring.

 

Well i changed the spark plugs and make sure that they were in the right order but maybe the other wires i could of put on wrong the black & white and the blue & yellow ones i believe i put them back in the right place is there any picture of how they should go...

 

are you talking about the wires on the coils, or the actual plug wires? cause the plug wires are just red..

 

The plugs I got I saw them labeled 1-4 but the coil wires I just want to make sure they're in the right place too
