Can any one shine a little light on an issue I have with my 650 Burgman 2003. When you take a 90deg corner eg into a side street the motor seams to rev higher but there is not much power to the drive. I have just had a new CVT belt installed and the clutch inspected but the issue is still there. It feels as though the power button goes on automatically. I have to bring the bike nearly to a stop then take off again. Any suggestions would be appreciated.

Anthony, if you have had the engine out to change the CVT belt I'd be checking all electrical and throttle cable routings and connectors to make sure nothing is being stretched/unplugged when the bars are turned a long way from the straight ahead position.

I'd also check the spark plug caps are properly secured.

Good luck, and pity you're not in Victoria as I would be happy to look at it for you.

Thanks Gary, This problem also happened before the engine was out. Sorry for not explaining it better when you lay the bike down to corner into a street this is when it happens not so much as turning the bars. I have also noticed if you press the power button at about 70km and off again it seams to he stuck. Can you explain how the power button works.

Sure sounds like a clutch slippage problem. How was the clutch checked? I would suggest that you do the clutch slipping check as given in the shop manual. The bike may have had the wrong oil installed that contained friction modifiers that can destroy the clutch in short order.

If you don't have an owners manual or a shop manual, I would recommend that you buy both as they will answer almost all your questions and will pay for themselves with the money saved by DIY.

Can you explain how the power button works.

All the power button does is access a different mapping in the ECM for changing the ratio in the CVT. That mapping holds the CVT in a lower ratio for a longer time.

how does the bike behave from a stand still take off, when you open up the throttle, does it rev high or take off normally?

the engine reving high as you take a sharp turn, it could just be a stuck throttle cable, double check it.

educated guess would be on your clutch slipping.... did they take it apart and examine all the plates?

good luck....

Thanks Ken I did they the clutch test by holding the front brake on and throttling and it drags the front wheel without slipping. Hi Buffalo does this switch have anything to with the PPS sensor. Hi LeDude the bike at standing take off sounds fine without any reving but when it revs high after cornering I have to bring the
E bike to a stop to get it to drive off again. Also when you try to press the drive button to manual when slowing down to a corner it flashes and doesn't change. What RPM would be a rough standard traveling at 100km/hr or 60mph. PS I enjoy your YouTube videos.

Not directly. All it does is change the set of computer code the ECM is running.

The PPS still does what it always does. It tells the ECM the position of the pulley face. The ECM uses that information to determine if it needs to move the pulley face to achieve the ratio it wants the CVT to be in. It does that whether it is in power mode or not.
