My 1990 Ninja ZX10 is occasionally missing and backfiring. I think I just need my timing adjusted but wanted to post up here for some suggestions.

I recently did a tune up which involved changing the oil, oil filter, plugs, air filter, and fuel filter. I am changing the clutch Monday. Other then timing what else might cause missing and backfiring?

Also if someone could spare some time to teach me how to check/adjust my timing before the next maintaince day (When ever that will be, Hint HINT!!!!) I would really appreciate it (Beer would be on me of course)

I doubt it's the timing.
Maybe ignition related (plugs) or carb settings.
Let me know if you need a hand.

Steve,
The plugs are less than 3 months old, but carb settings could be it. One thing I forgot to mention in the above post was that this bike spent 6 years sitting still (6 months of that outside).

Yes I could use the help, I appreciate the offer. We can talk about Army flying (I have the right guy, you were a cobra driver?). PM me if you can spare some time this week to give me some guidance on carb settings.

One other thing I forgot to mention regarding the timing is that when I first start the bike in the morning or when cold, I have to leave the choke on for a good 5 minutes till it warms up or it will die. During that time I have to increase the idle setting until I can turn off the choke and then turn the idle down to 1200 to 1500 rpm.

Still doubt it's timing.
Might have fouled a plug with that much choke use.
Deff need to look at the carbs...

Timing wouldn't act out all of the sudden like that.

I would check each plug for spark. Another thing is if you have the need for so much gas, maybe you are running "very lean", i.e. an air leak. Check you little manifolds, if they look all crusty, maybe is time for new ones.
