    Hi I'm replacing the engine in my ninja. does anyone know the tools that would be needed and know of any good step by step instructions. I have the manual but its very disjointed and rather than going through the steps just tells me to refer back to other pages etc. Any help would be really...

    Ninja 300 Parts & Accessories
    I don't know much about engines (slowly learning) so could anyone help? The mechanic says it could be a cracked gasket head or the seal has gone but its a long and expensive process to strip the engine and find out. Anyone have any suggestions? p.s I'm looking at moving to canada in the next 6...

  7. Leak in front of engine, head gasket??

    Ninja 300 Issues and Troubleshooting
    I purchased my bike back in october of this year, about 6400 miles to date. After my last ride I noticed a slight coating of fluid in the front of the engine, I think its an oil/dirt mixture. I wiped it clean and had to put it away for the winter. Images are a little hard to see, but the fluid...
  8. Ninja shutting itself off

    Ninja 300 General Discussion
    Hey everyone, So this has been happening maybe for a month and 1/2. I have not thought to much of it until today. I notice it happening mainly when I leave my condo by the time I get to my first stop sign 1 out of 3 times the engine will shut off. Then I have to switch to neutral and hit the...
  9. Bike taking a bit longer to start

    Ninja 300 Issues and Troubleshooting
    About 1600 kms on the clock. Started doing it at I'd say 600-700 kms. Basically, when the bike is cold (it may be 30°C outside, but the bike hasn't been ridden for the day), it takes a bit longer to start. It was starting really quick when brand new, now it tries to start, then stops and then...

  12. Ninja 300 engine braking

    Ninja 300 General Discussion
    I am wondering about the rough engine braking. Is it normal that a motorcycle brakes that much when going off the throttle for 1mm? Its my first bike and I cant remember, how my msf machine felt like. Even when I roll off the throttle as smooth and slow as I can, the 300 bumps. 6th gear...
  13. Broke Down

    Ninja 300 Issues and Troubleshooting
    So on Friday I rode my new 2014 abs ninja home. Not a problem. Today my friend and I went for a nice Sunday ride and got about 5ks and my engine cut out all of a sudden and my oil light came on. I'm thinking maybe the dealership had put in the wrong oil. Like a lower grade oil. But I'm not too...
