A 70cc with a pipe and CVT tuning and maybe a carb can make a good scoot without a whole bunch of issues. That said, I have to agree with others here that after seeing your other thread, I can't think this is a good idea for you. It will not be a matter of bolting on the BBK, installing the pipe, and then installing rollers/sliders, clutch springs, jets and settings exactly to a spec and riding off happily ever after. We had a hard time just getting you to do things like a compression test or cleaning the CVT. Actually, I don't think either of those was accomplished in however many years that thread went. If you don't want to do that stuff for a stock scoot, don't modify it. It will only get worse.
BTW, I've had that stock muffler that you wanted packed up sitting on my table for almost 2 months now. Last we spoke you were going to get back to me "next week" (in May) with the $15 I was asking to cover shipping. If you don't want it anymore, no worries. I just wanted to know so I could move it back to the shed instead of sitting on my table ready for a shipping label.

I use this scoot mostly daily and for pulling our trailer. What? You mean something like this? Nope, more like this:  Different scoot, but same trailer  Dunno if one can see, but here is a 1996 Honda Bali 100 on the trailer. So a scoot pulled by another scoot.  |

My 2C
Our Vino is stock, except for 3.0x10 tires, and a $60 eBay expansion chamber. A little playing with the variator weights and springs, and it quickly reaches 45 on flat ground (I am 250lbs) I know a Tiny bit of work and 50 would be easily achievable, but I am planning a 70cc kit soon and more tuning.
Doing a BBK is of course a great way to build power, but much over 50 mph means a lot of rpms and short crank life.
But 50 is easy😉

Best and most reliable and pain minimizing way to get 50: if you have 10" wheels, sell it and get a 150; if you have 12" wheels, put a 150 motor in it.

it is possible to get 50 out of a scoot without alot of work but you have to do some. stick a better carb and exhaust on it and it should be able to net 50ish. the zx-r exhaust would be a good exhaust for that. good lower power torque and lower cruising rpms at 50ish. get a malossi overrange or similar variator and you could get a few more mph with smoother acceleration if you have the power for the extra gearing. or get a mild big bore kit to go with new exhaust and car with overrange and be in the 55-60 range top speed if you have the gears for that. stage6 makes a cheap cast kit that says 50cc on it and it pretty reliable and athena makes a 70cc sport kit thats aluminum that lasts forever and has great power. i used both kits for over 5,000 miles the athena i sold used to another member. i had to add gears so the athena kit would stop doing wheelies all the time.

been riding it lateley and have been hitting 40 down hill haha. 35 flat with no wind. but my father in law is the cheif of police in my town and said your average cop isnt going to be able to tell if its a bigger motor or not. so i guess i could go bigger but do not want to spend the summer getting it bored out or swapping motors. just thought i could get a few more mph with some cvt trickery. like differnt rollers or clutch or something along those lines.

"cvt trickery" requires you to get familiar with disassembling and reassembling the CVT. like having the tools so that you can break the torque on the variator/crank assembly and to break the torque on the clutch bell nut. and if you want to delve further into the clutch and torque drive (rear pulley), you will have to learn how to safely remove the clutch nut. I think your CVT probably needs some maintenance. a cheap mod would probably be changing the variator to one that gives better performance. I have only run KELI high speed variators now because of price & availability here at local shops. I like the way it performs for the price of it. |

What are some common maintenance with cvt. I mean obviously the belt but what else can wear out? Do they sell an all in one kit to replace everything? Or better off pieceing it together.

The belt and rollers are the things most often replaced.
I have always just purchase the parts I need individually.

Or better off pieceing it together. belt gets narrower, rollers flat spot, ramp guides wear out or break, torque drive pins in rear pulley wear and wobble, clutch pads wear out, clutch springs fade contra spring loosens. if you really have aspirations of going 50 on your scoot, you should be learning how to uninstall and install these parts. it's tuning the CVT, and that's how it's achieved. |
