kawi ZX7R hard to start after riding.

[IMG]C:\Documents and Settings\Justin\Desktop\My Kawasaki Ninja\0ffe_12.jpg[/IMG] Hi im new to sportbikes and i bought a 93 ZX7R it usually cranks right up at the beginning of the riding day but after about an hr or so of riding if i stop and shut the bike off to go in somewhere when i come out it is very difficult if not impossable to start sometimes. (fuel is on, in run with key onwill try to turn over but not fire up) Please help me i have had this bike for about 4 days now and it is getting very irritating and im tired of hearing sh#% from my wife about it. Any suggestions or comments would be appreciated.

Spark plugs brother. Change em. I can almost guarantee it fires right up.

Also, are you sure your turning the choke off after it is warmed up?

If it's that old you probly dont have an owners manual with it. Look on eBay for a service manual. I'd go with whatever the manual recommends. I use NGK.


Also while you're at it...you might wanna do a complete tune up. Get her in top working order.

I always try to start mine first with out the choke. Usually it fires right up...even after it hasn't ran for several days or a week. Try without...but dont flood it. Hit the button once or twice and if it doesn't fire then choke it.



My bike is a 92 GSXR 750.

Hit up the oil change. Check out the plug wires and coils. Probly a good idea to have valve clearance checked too. As well as fork oil swapped out. There's a lot to do. A service manual will give you a better idea.

well, when i bought the bike in Oct. of last year they said 'they changed the
plugs, wires, oil, filter, fork seals, new rear tire and lubed the chain'. along with a few other things that i can't remember.

other than seeing the new rear tire, i hope they did.

i'll have to check like ya said, marko.

I wouldn't trust them. At the very least I would have changed the oil the minute I got home. And if your chain hasn't been lubed since OCT...you might wanna do that too.

Go to your dealer to get the stuff for the oil change and the plugs.

Are you choking it when you go to re-start it?

What are you doing with the throttle when starting it?
