You own 1998 zx6r will not start just backfires?

Answer 1

I had a very similar problem w/ my 1998 zx6.

My problem was: I'd press the button, it's crank crank backfire.

What I did for testing that figgured it out: Turn off the fuel switch. Leave it over night. Turn on the fuel switch + start immediatly.

If it starts and runs what's happening is your tank is rusty on the inside. The rust clogged your fuel filter and has jammed the needle in the carb open so fuel is pouring into the cylinder. It backfires because when you start it tries to compress the fluid in the cylinder.

Take the tank off, the air filter, and then your carbs. Go get the carbs cleaned, change your oil because the gas will have slipped past the piston rings into the oil. OH and change your spark plugs (somewhat unrelated but since you're there anyway, mine were pretty fouled)

The tank itself: I used the Kreem kit. It's a three step system to take the rust out of the tank then coat the inside to prevent further problems. It's not a very graceful process and if I could go back in time I think I'd try to find out how much a paintshop would charge me to do the work.
