hi all..was wondering if anyone had the case of bad fuel milage...on a tank of gas not getting very many kms on it...is there something that needs to fixed...or cleaned....or something else? also it has been hard to start..at times..like it was never gonna start at all..i think this is all linked together thanks

 

Good guess. Your problems might be all related. Check following:
1). Check for fuel contamination by drainin your engine oil.
2). Check choke plungers are REALLY closed when choke **** is at OFF position.
3). Check carb float valves for any sticking.
4). Check function of your 1-way check valve at the fuel tank vent.
5). When engine is not starting (when just clicks and not turning over), remove spark plugs (both) and try to crank. Wear goggles and see what might come out of spark plug holes.
By the way, what gas mileage are you getting?
Good Luck.

 

i notice it getting worst...to me anyway the past few times i used it...but yesturday i noticed it alot...i might of got 50kms...i dunno what the conversion is over to miles.....but thats not very many on a full tank..and i was just using it on the back dirt roads and paths through the woods....i use to get close to 80 or more...im just glad one of my buddies did have extra gas...or id have to be towed out... and they still all had a half a tank....

 

50 Kms is about 31 US miles. Your 650 has a claimed 4.5 gal fuel tank before reserve. Assuming you topped it off before riding and you rode until it ran out of gas, you got 31/4.5=6.9 miles/gal. I don't know how you ride and what condition your bike is, but my 700 gets any where from 15 to 25 miles per gallon depending on how I ride. Do the things I wrote above, and read your plugs as well.
Good Luck.

 

yes my tank was topped off,even shake the bike some to, get the air out to add a lil more..and my bike is in great condtion..as for how i ride,im not a person thats hard on bikes..so i cant see that would be a issue..as for the tips you gave me havent looked yet...

 

Man you have bad fuel milage... I get about 120km plus when pushing it to the limit. Alot of my driving is mixed from fire roads to trails to mud. The way yours sounds it must have the choke stuck half on and flooding itself constantly??? Whats the exhaust look like? Do you shut off your fuel when bike is sitting? Are you running in Low range all time? Must be something? My machine can be tricky at times.. Ya kinda got know when to choke it or not.. and when she idles down from high idle shut choke off.. Try using a tank of High Octane fuel through it and see if you have better milage.. Thats all my bikes ever had.. Hope you find the problem..

 

lol..yeah i know im getting fuel milage...and i also use high test gas..thats all i ever used in all my bikes..on most of my bikes i had i could tell if the choke is stuck on. but i did read somewhere,about a faulty choke cable on the earlier bikes..maybe your right and could be the problem...i shut my gas off when not in use...i hardly ever drive in low gear...i never go anywhere to use it..

 

I have a bad fuel milage too ! I have a p650 2003 (buy in 2005). I can run only about 70-80 km with my Kawi. I think is very bad but i dont have check if i have any problem with my choke. I also turn my air screw (under de carb) 2.5 turn and still running better. If i solve fuel problem i write to you.
Thank for all info on this forum

hey ScoobyGB , i did a few things to mine as mentioned in this thread, as i was getting and still do get bad fuel milage..so im gonna take mine back to the dealer to get it checked out cause mine is real bad....as i just dont use it much this time of year i guess im just delaying it lol.....so let us know how you made out with,or fixed the problem could be something simple im not doing...lata...

 

What kind and size quad do you have?

I get about 85 miles per tank on my P650, and that's riding it hard at high altitude. Don't know about my P700 yet, but it's not as good.
