Since nobody responded..... Does anyone know what other Kymco model(s) have the same motor? (If any?) That way I can just cross-reference a more popular model. Also, I did end up finding a 70cc kit, But it's located in the UK. And I'm still not positive this model is an SF10. Anyone?

Okay, So I have some time & cash to roll out and tinker with my 2T Yup 50 again..... Does anyone know what big bore kit is a direct bolt-on? I'm pretty sure it's an SF10 motor? Please correct me if i'm wrong? I see tons of 139qmb kits, but nothing for an SF10. Is the SF10 basically the same as the 139? I've read that these are decent engines? again, correct me if mistaken? I understand that most of you are not familiar with this model as there's not even a section for it on this forum. It's basically the same model as the "Sting", which is the UK version. Thanks

The nut is tight.... Yes, Washer is under shaft nut.... Variator does wiggle slightly. Well, I was planning on purchasing a "Race" variator soon... guess now is the time! Any suggestions? Whats the best size roller weights for a decent trade @ faster take off?

Opened CVT for visual inspection and didnt see anything abnormal.....I didn't take off variator though. Took it for a short ride and it's not doing it anymore.... Could it have possibly been the roller weights jammed? Am now feelin not so confident in long rides.... Way too hot here to be pushin a scoot around!

If I had to guess, I would say it's coming from CVT somewhere. It's funny you mention that, As I did have it apart last weekend to see if drive boss was de-restricted.... well it was, so I put it back together. I've rode about 200 miles since then and all was fine until today...... If the nut came loose, wouldn't it do this at any acceleration then? Why just at 30+? and yeah, It sounds exactly like a weed whacker!

Okay, So took a ride this morning and was hittin 50 riding with the wind. On way back into heavy wind I was riding along @ 40ish when all sudden it started making a winding noise and there was no acceleration. I slowed down and took off again, rode smooth up til 35-40 and started making the noise again and no acceleration. So I babied it back home and figured I would ask the guru's here before I started opening shlt up..... Any idea's?

I'm still @ 47/48 mph after splicing CDI wires..... The same as I was before! It does seem to get there a bit quicker though? Anyways, Thanks for the help. Now off for an evening ride over the bridges

So completely cut light green and splice into darker green? or just splice into light green and splice in darker? I've read all kinds of different approaches now...... Am dizzy!

2001 Yup.... Can someone tell me if this CDI is restricted? And if it is, How to derestrict? I've seen posts regarding other scoots and cutting, then splicing light green into green..... Just want to be sure though. Pic of unit attached

Hey Colourcode..... Is your Yup de-restricted or factory? And how much do you weigh and what's your normal top speed?

Correction: I think it's actually a Honda part number..... And pretty sure Honda use to make Kymco. Either way, That is the correct part# straight out of the Yup Part manual.

Not sure about UK as I'm in the US.... I pretty sure that part number is stock for all bearings of that size, Not just limited to kymco. I have a 2001 Yup and that part# matches both my upper and lower as they're the same size. I know Yamaha and Honda use those too. If you google the number, you can find a dealer that sells them in the UK?
