i believe you need to adjust your float hieght.
i think thats what controls your fuel under 3k
i would try to find the stock hieght and go in and reset it.
i dont know a whole lot about carb work, so hopefully some one else here can help.
It could also be chuggy because its low horsepower engine and you are lugging it. Its not a car engine which redlines at 6000 rpm but a bike engine that redlines around 13000 rpm. You drive a car in the middle of the rpm range, which is 3000 and you should ride a bike at the middle also which is 6-7 thousand. It sounds pretty normal what your bike is doing, unless its violently "bucking" then its a problem but if its just pulsing alittle under 3000 then your ok.
When was the last time the carb was cleaned? Friend has 01 ZX6r, that sat for 4 years with gas in it, I cleaned the carbs yellow stuff came oyut bike ran 90% better, his lazy ass still hasn't replaced fuel filter.....to get tip top.
I dont know when the carb was cleaned last. I bought the bike about 5 months ago. Is it easy to clean myself? Could it be done in a day using a standard socket set? Or would I need any specialist tools? - Sorry, but I've never had to do anything like this before!!
Go buy a clymer and read the manual and go by that. Very explanitory and will help alot. Sometimes the manuals cover a couple different years or models but the info is the same just the picutres may be different.
Be extremely careful when unscrewing float bowls, brass screws strip soooo easy. I ended up using a cordless drill with a phillips tip and set the torque to 10, took the screws out butter! I had an extra set of hands hold the carb still, while I unscrewed.
Good one, Also be carefull with all the little orfices (sp?) dont try to clean them with something like a steel wire. You can use copper wire to clean as it is softer then the carb materials. You dont want to scratch or gouge any of the jets or orfices in the carb as they are made to very specific sizes.
ya, make sure you use good tools too. If you dont at least have something at least as good as craftsman you might want to go and buy a screw driver set of that brand. The cheap stuff just doesnt hold the screw head well and will slip causing a stripped out head or a big hole in whatever your screwdriver slips into. Hand, carbs, leg, HEART!! Ok maybe not that bad but you can injure yourself or mess stuff up with poor tools. Do it right use good name brand tools of at least craftsman.
