Hi raiders,
I have a 2014 Suzuki df50 with around 20hrs on it. The other night when I took it out crabbing I noticed it was making a strange noise. At idle and in the lower revs, it would make a belt slipping/sucking noise from the front of the motor, near where the cowling cover joins the lower half of the motor.
It wasn't all the time, only intermittent and it did it in neutral and whilst in gear. I could get it to go away sometimes when in neutral if I gave it a quick rev, then backed off. But it would come back. Not sure if it does it at higher revs as the sound of the motor kills it out. Also I couldn't get it to do it when on the mufflers, flushing out the motor. Any ideas???
