Fitting new drive belt to Yamaha Majesty YP400

SOURCE: V-Belt flashing

Hi carms

Even although you have just had it serviced, the warning light is triggered by the mileage traveled. So if the belt appears to be Ok, then resetting it has to occur at the point when the indicator comes on. Having said that, I understand that scooter belts can weaken (and break) from internal weakening over time (heat and stress) and not just from external wear and measurement. Over the years I have read about belts breaking (other scooter brands & models) from high use and/or mileage even though they still externally measured within spec.

The "service limit" for the Majesty belt is 27mm (shop manual) or 12,500 miles - so to be safe it should all be interpreted as "replace belt upon the soonest of 12,500 miles or 27mm width"

If they have not replaced the belt in your recent service, then you could perhaps return to them to have it done, or reset the idiot light for you. OR you could do it yourself and see how you go.



If you're wondering where the area that the diagram above is indicating, the reset coupler is the white plastic coupler located under the tailpiece where the battery is located. The rubber strap securing the battery holds it in position and it is the only white coupler in the vicinity of the battery. I also read that you need to have the park brake off to perform this exercise.


I got some of this info from a great site dedicated to your bike. Check it out here. Thanks for using FixYa. A FixYa rating is a grewat reward for my time taken to address this with you. Cheers!

Bruce, take a few rough measurements from both engines. Measure at the frame mounting locations. If one location measures 6" and the same location on the other engine measures 7" then obviously there is a swap out problem. If the rough measurements appear to be very close it will likely work. The only way to know for sure is to try the swap. It may be possible to cut and relocate a mount or two to adapt the frame for the new engine. Just be sure the chain lines up with the rear sprocket.
