01 zx9r it feels like its starving for gas between 5 and 8 grand

Is it fuel injected, if its carburated it might need adjusting

1. Sounds like maybe fuel line from gas tank is clogging. Clean gas tank. To check, remove some gas from tank and run it through a paint screen.
2. Replace gas filter regardless.
3. Could also just be water in gas tank. Drain some gas from lowest point of tank (usually the reserve), into glass jar. Water should settle to bottom.

sorry i dont know...

not everytings perfect--theres a clog or weak water pump and the circulation doesnt match the rpm-buy a clymer manual

HAVE YOU CHANGED THE PLUGS AS A FIRST STEP

Could be your crank sensor has gone bad.

You are a new bike rider ... first thing ... don't get mad - don't exceed the speed limit ... I don't care what color your new machine is or how cool you think the girls will think you are while scaring the daylights out of old people and dogs. It is not cool. (insert boys if appropriate)

Due to the nature of this site - I have not seen your other question ... so I cannot comment.

To your questions, there should be a dip stick on the right hand side of the bike. Check it ... don't over fill it. When empty, it will take probably around 2 quarts. Do not depend on using all 5 gallons of your gas before you refill ... best advice I can give you is fill every 100 miles until you get a feel for your mileage. There should be a trip meter on your bike - set it when you fill up with gas. You know about the 'reserve tank'? Never turn the valve to reserve unless you are out of gas. Otherwise, you WILL be out of gas. Pushing a cool motorcycle is not cool.

If you have a tach, there should be a red line on it ... NEVER EXCEED IT ...

is your bike all stock? how many miles on it? sounds like a carb issue. try draining float bowls into clear container so you can see what came out.(water dirt etc)

you are supposed to jet any bike when you put a high performance pipe on it. you can damage valves and rings even with a slip on. i am using a stage 1 dyno jet kit with a yoshi rs3 oval slip on.
