Evening. Had the belt changed today on the Dragster 50 at local mc store. Riding home which is 13 mile it doesn't seem to be pulling under load or reaching its top speed. As a example it usually tops out around. 60 on the clock and is struggling to 50 on hills it's down to around 25 rather than 35. It's seems to be revving differently as doesn't seem to want to pull under load. Can these be fitted incorrectly is there anything I can check before I have a major rant tommorrow.
No just the belt. The previous one hadn't snapped I just didn't know when it was last changed. I've just read they take a bit of bedding in as well as they have some form of preservative on them which burns off.
