I just came in from the garage. The final 2.88 drive gears are out but I don't have a press so I'm trying to figure out how to press the 17/49 gears out and return my final drive to stock. I dread having to go to HF and spend $200 ($158.00 with a coupon) on a press but I tried the brass hammer approach and after beating up the brass hammer pretty bad, the gears haven't budged.
I'm 100% convinced the 17/49 gears are just a bit too much for most upgraded 50cc 4T scoots....even with a 50mm BBK and cam and some other light mods.
You'd have to go stroker and a bit more exotic stuff to get even a 50mm BBK scoot to push these gears on top end (bottom end and mid range is ok kinda)
So, I'm going back to the original final gearing of 14/52 (3.71) and install a brand new belt. I think my drive belt has worn enough to get narrower and that's why my top end has suffered. Common common stuff....I feel like an idiot.
That said, I do think a change to a 3.40 ratio might be good compared to 3.71, at least with a 50mm BBK or above.
I just have to decide if I'm gonna get a bigger hammer and keep whacking....(and possibly damage the gear shaft) or go ahead and plunk down the money for a press. I'm REALLY outta room in my garage is the problem. I gots da money. But then I'll have this big press in there year round, taking up space that I'll probably hardly ever use.
