Tune up my '95 ZX6 44k miles?

Right here's the deal, new and all to the forums.

I bout a 95 ZX6 roughly 3 weeks ago. seems i bit of more than i could chew,
I already had to buy a replacement water pump due to oil leak then set of new tires.

Now im starting to have more problems! the bike is now doing only an average 60-70 miles on a FULL tank which i know someone with a ZX7 will get 160 out of a full tank.

Also the bike will spit, sputter and looses all power when reach anywhere from 90-110mph at 1/4-WOT also i have flat spots at all different intervals in the low, mid and high rpm which only will happen AFTER 3rd gear below that low spots are up to 4,500rpm

The bike has 44k on the clock and the guy never really gave me a straight answer on when it was last serviced so im wondering if i should check all valve clearances, plugs, or air filter!

Really would love your inputs on this!

And you might want to use this when you check / replace your spark plugs.

Thanks for your input! my service manual has something very similar to that with pictures of certain plugs, saying what caused it and what to for in the motor when it occurs!

It sounds to me like you need to do a tuneup alright. when you buy a bike, that is THE FIRST thing you ever do. trust nobody, people lie, if you do it yourself, you can trust it was done and know exactly WHEN it was done.

air filter, oil, oil filter, maybe get the valves adjusted, just get everything in general checked out and put in tune.

thanks alot i knew i was in for a bit of workbut it doesn't bother me that much at all, sure money is tight but the experience in finding the problem, understand why its happend and fix it.

I have been told when rebuild or cleaning the carb to pay particular attention to the pilot jet,

Something else struck to believe to do som possible carb work this morning. I randomly took the left air duct tube off which connects to the airbox and i could smelt slight trace of gas inside, too rich? well i'll keep you guys posted when i start tearing down the bike

Thanks all!

Right time to report!

I have strip down the bike and have found that the aircleaner/ box was clogged and a death field of dead bugs and sort!

Also all plugs were indeed carbon fould cylinder #4 being the worse.

Now i am confused the NGK plugs that were in there were CR9E yet my service manual (for 85-97) it says to use D9EA which one should i really get?

Use what the manual says. the wrong type/heat range will cause problems in some way or another.

Then in that case, I'd go ask the dealer what THEY say is the right plug, usually they've got the right info.

When I did the tune-up on my 95 ZX-6, assuming you're talking about the ZX-6E, I used the CR9E plugs.

I had the same air filter. Did you also get the oil kit for oiling the air filter? If not, K&N makes one that Autozone carries.

I've got (from the sounds of it) the same bike -- '95 ZX6R. She sat dormant in a shed for a year before we bought her, so we replaced tires, battery, spark plugs, oil and most importantly had the carbs re-built. Best thing we could have done for her... she runs like a scalded dog now... 11 years old, and (now) 36,000 miles on her.
