Not question just a heads up/education. I've had many folks say that if a belt has the right OEM number it's the right belt. T'aint so.
Bad Boy belt number 041-5048-00, used on Pups and Lightnings and several others, has been seen on many belts but most are nowhere near spec and most are too short and too "fat". You should be looking for a Narrow 5V belt, 15.8MM (.622in) top width, 14MM (.55in) depth) and 81.1inches long. Invariably the top width non OEMs send is 5/8" top width which makes it ride higher in the the groove(s) and reduces effective length further. They also send belts that are generally barely 80" long (you need a belt measuring tool to tell as it's usually not accurate if you try to measure and adjust for all the factors). You need 81" for some of these belts. And the belt should be a "raw faced" belt, that is, one without a Kevlar cover or some other cover type....those make the belt fatter and inappropriate for the same reason given above.
Now, you don't have to buy a Bad Boy branded belt but you SHOULD be asking the vendor for the exact ( top width can go to .600 inches but length can go a bit less than 81" ) measurements given above. And ask if they used a belt measuring tool. Some will lie and they just get the belt back on their dime. If you have another Bad Boy belt number specified for your machine the best time to get all this data is when it's new or take the measurements from a Bad Boy supplied replacement belt.

Yes the belts has to be a little longer when 5/8 raw edge are used. Remember 5/8 is .625 of an inch.
Also you should replace a Raw Edge (non-clutching) belt with a fabric covered (clutching). Stens sells a 5/8 x 80.5 raw edge and Rotary sells a 5/8 x 80.25 raw edge belt as replacements for the 041-5048-00

Both may be too short. 5/8" top sticks up above the stock sheeve and the effective length thus decreases. The bottom line is the top of the belt should be even with or just below the top level of the sheeve as there is not a lot of room coming off the tension pulley where the belt faces pass. I have no idea why you think a fabric covered grips better than a raw face...exactly backwards. Fabric loads up on oil and gets greasy. Besides, OEM is raw faced.
Just got off the phone with Stens. They have no idea where they got the length of 80.5. No clue. Yet the Bad Boy supplied is just at 81".
