Pulling When im riding my ninja on the highway or running about 50m.p.h. i can feel my bike pulling back and accelerating a little bit. and ive also noticed that my acceleration is no where near what it was before this problem occured. My bike was running fine the night i put it up, the next morning i took it out and it started this. I put a bottle of octane booster into the tank my last fill up a day before the problem. since ive used that tank up. any ideas on what this may be and solutions is greatly appreciated. Thanks, steven

Hi Robert,

use little bit glue on it .Super glue or lock tight or auto paint drop is ok.
tune up and put little amount glue .it is enough to stop loosing screw.

After u rebuild the carbs and it dont clear it out check ur cdi they are known to do crazy things!

is there any leaks from engine to exhuast

hi there i think your jets are blocked in the carbs , need to strip the carb and cleen the jets and the bowl ect.. hope this helps

Check for moisture in the killer switch unit and spray some contact cleaner or penetrating oil inside the main key switch.Also it would be nice if you check the joints in your harness from the cockpit to the rear brake like.Usually the copper contacts turn into green from the moisture.Use a little bit of lithium grease before you click them back together to prevent moisture go inside again.

Do you have a "RAM AIR" system on that bike, if so that may be what happens when you ride into a headwind. The bike may be running a little lean and with the extra intake pressure goes too lean.

buddy you have to get your bike to an authorized service personnel to tune your air filter and fuel screw since these are like lungs and heart for the bike.any self adjust of these things may lead to unwanted consequences.(mostly get your carb cleaned since even moisture or water wash may caused water to enter the carburettor)

Yes! You will open those things up, and they will probably look pretty clean, but the problem with your carbs is in the Idle circuit - too small for you to see into. If you do a search of carb cleaning or related topics, you'll see that alot of folks with cab problems try to clean their carbs ... only to have to open them up again due to improper cleaning (They are difficult to clean properly, require alot of patience) So, I would suggest that you have them cleaned professionally, or at least buy good carb dip to get them really clean. Spray cans of carb cleaner are worthless. Might as well wash em with dish soap.

Next time it happens, pop the gas cap and see if the problem stops. Can you hear/feel air rushing in when you open the cap? If you can, you have a clogged gascap vent. You can try to take it apart and and clean/fix the one you got, or just buy a new cap.

but im not really feeling the love for it. the main problems i have at the moment are that the front and rear suspension are really soft its ruining my cornering confidence and making the bike uncomfortable to ride. im 20st and 6'5 so there is a lot of me to hustle about. the hagon shock that the previous owner put on there has not adjustment other then preload and im sure the spring rate is miles off what i would need whats a good replacement shock for a guy like me? also the clutch is very heavy with little progression its either on or off so im finding riding in town hard work as well as slipping the clutch in corners. lastly the fuel economy is pretty poor, i only got 93 miles before my low fuel warning light came on. so any suggestions? because at this rate im considering selling it to get something a bit more pedestrian for riding in london like a fazer 1000.,I wasn't feeling the love for my falco for awhile either. For reference, I'm 6'6 and about 250 lbs. Helibars are a must IMO. Also, my level of hate went waaaay down when I installed a smaller (-1) front sprocket. Being able to get the bike into corners at the right revs (and torque) reduced the amount of braking I did, which let the suspension settle down. Toss the stock shock. They're great bikes, you just have to get it set up for you. ,,,
