I fitted a gates powerlink belt yesterday, 729-17.7-30, and my scooter went to sh**. Hills I would go up at 30mph I dropped to 22-24mph, lost top end, acceleration went real bad, no revs. My stock belt is 729 so I knew it wasnt that.
Took it all apart today and removed the gates powerlink belt to measure it just in case. Guess what, its not 729mm long its only 716mm long? Wtf? It says 729 on it too???
Put in the Nakura 729 belt I had and now its back running ok again. Surely a 729 belt means its 729mm long? Was listed as 729-17.7-30. I just emailed guy to complain and say I want a refund cos its not a 729 long belt he sent me. Just measure all new belts now from now on before I fit them. Had my head scratchin on this till I measured it.
