I fitted a new sensor and my bike does not start at all after fitting. Before I fitted the new sensor, I took it to Truimph and they had it on the dianostics and they told me to fit a new sensor.It also had a problem to start with the old sensor.

    Air temprature sensor on the airbox.Before my bike also had a problem to start, specialy when it is cold.I took it to Truimph and the diagnostic showed that the sensor need to be replaced. It also smells madly fuel when I start the bike.

    Thank you for the advice, and will do it. Strangle, when I push start the bike, it stars, but puff a lot. I will give feedback on your advice.

    What kind of sensor is this? What were the symptoms before and after?

    Many sensors (O2 for instance) you can simply disconnect it and try.

Thanks for your feedback. When you say "It also smells madly fuel when I start the bike." does the bike start?
I'm going to assume not.
I don't know much about Fuel Injection but there is three things motors need to run - compression, fuel and spark. It sounds like you have compression and fuel, so we need to check for spark.
Chances are the plugs are simply fouled with gas. You can simply buy new plugs (esp if they're old) or check the existing ones for spark.
CHECK FOR SPARK The best way is to remove all of the sparkplugs, re-connect them to their wires, rest the threads against a good ground. Turn the motor over and look for a good fat white spark.
If no spark, make sure all 'safety' switches are in a start position (side stand up, neutral, kill switch on etc.)
Good lcuk & let us know!
Be sure to put a dab of neversieze on the sparkplug threads when re-installing.

    Thanks - puffing can be plug-related too!

    Good luck!

Try an auto electrician that does bikes, you can usually fit a relay/booster on starter motors to give it that initial boost, i tend to agree about your mechanics.

What new parts were fitted? Were there the same issues before the parts were fitted? There may be a compression isssue due to a poorly fitted part. This will become evident as the bike becomes warm and parts start to expand with heat.

I bought a new seat for my 1996 Fuji Sagres. The old saddle clamp is too narrow for the new seat rails. Where can I buy a different sized saddle clamp that will fit my bike?

take it to a bike shop and get a new seatpost. bike shops
have manuals that they can check to find a seat post that
fits the bike frame and has the proper size rails to fit your
new saddle.
this is a good time to upgrade the seatpost, you can get one
that is lighter and more adjustable that your old one.

Kick start thinggy on the engine as rounded off

Usually a Honda part will fit those pit bikes. Honda 50-150 cc should fit. Take a file and clean up what you can of the splines on the shaft going into the engine. Fully remove the bolt and nut before removing the kickstarter as the bolt is in a groove to help retain the lever. Refit the new lever and tighten down well......Good luck to you...Tim

No spark

alrighty, I had the same issue with my bike. It took days of tracing the issue with a volt meter and I discovered an intermittent short that would "fry" my coi. This made the bike not start and when I replaced the coil, because I had removed the old coil and moved the wires the issue disappeared for a short time. It is known that SOMETIMES when the coil is mounted the two wiresthat go to the coil somhow get stretched. This over time cause an intermittent short and the coil is rendered "dead". The Fix: 1.get a replacement coil. need 6 inches of #18 wire 3. two aluminum wire splicers and two aluminum circle fittings for the coil posts. 4.take off the old coil. 5.cut back the wires that go to the coil about an inch. 6. using the aluminum splicers splice the wires making them about 3 inches longer. 7.splice in the aluminum circle fittings. 8.mount the new coil. 9. fire the bike up. Enjoy riding.

Flatspot on acc but intemitant

I would look for air leaks downstream of the Turbo. And if you find nothing there my best guess is a bad airflow meter.
