faulty injectors. try a fuel system cleaner (cheap option, may work) other wise new or refurish injectors

I haven't had a motorcycle in a long time,but all the bikes I remember had the VIN on the frame,where the forks attach(the short tube on the front of the frame that holds the bearings for the front wheel to pivot left or right).This might be a little tough to see on a sport bike,but it should be visible without taking anything apart(so it is easy for the police,DMV,or an inspection station to verify).

you dont its done with engine oil

You can find a free pdf service manual on this site.
I checked and yours is on the list.

Hi and welcome to FixYa,

To my knowledge, 1 3 4 2. Electrically, leftside ignition coil powers sparkplugs 1 & 4, right side ignition coil powers 2 & 4.

Good luck and thank you for using FixYa.

gday there your problem might be that your fuel pump might have stopped running ,these can sieze up running empty ,it may have a blown a fuse ,so that might be something to check ,if not it may be one for the dealer cheers pete

It is better to replace it with a performance version. K&N filters sells them on-line and you will be very pleased with the results. Changing your spark plugs to Denso Iridiums will also provide a little power boost (HP up) and improve fuel economy.

Hello and welcome to Fixya, It can be done, one of our competitor's race teams did it with some pretty drastic modification's. Its definitely a challenge.But seen it accomplished. I could give you there info, they may be able to give you some hints. Let me know, Thanks for using Fixya

does the engine turn over but not start or does it not turn over at all

you should have a header tank some where on the bike you fill this to add water to the rad.

If you mean the bottom of the tank then one goes to the carb and one is just a breather/overflow that gets ran down out of the way and doesn't connect to anything. If you are talking about the carbs then one goes to tank and one goes to the vacuum

Fuel system is clogged,..GARAUNTEED!! Take off the fuel tank,to get to the swirl bowl. Inside the swirl bowl,you will find a fuel filter,which SHOULD be completely white,and most likely,its not! Get a new filter and install it. While you have the tank off,disconnect the injector line,and remove and clean the injector with carb cleaner and pressured air.Put everything back together,and then add an INLINE FILTER to the feed line on the fuel pump which is located on the left hand side,running from the shut off valve,to the fuel pump. These are awesome quads,but the fuel injection system is a pain in the a$$.Good Luck!

They don't go too high on their own, someone has to have maladjusted them
It could be a leaking float, that will amount to the same fault. Or, it might be the choke is stuck on.

Are you out of oil?

Given the year of the bike there are a few things you will need to look over

*Check your break pads for even wear
*Change your break fluid
*Check your clutch lever (it should move about a millimeter before it actatually grabs the clutch)
*That bike has carborators. They need to be cleaned (could be part of problem 1 and 2)
*Check the fuel tank for rust. (there are treatment kits if it is rusted)
*your throttle cable should be lubed with cable lube(part of problem 1)/(when you pull the throttle cable then let go it should snap back closed)
*get higher octain fuel (this will help with problem 2)
