No link, im just too lazy but you can search "tgb primary gear" or "tgb secondary gear" there is like one for each.
Factory gearing is 11.83 which is 51/10 and 35/15.
I actually messaged Jwhood because I knew he had a TGB he used for parts, about this:
Apparently some TGBs have a 49/11 gear instead of 51/10 but also have a higher gear ratio for the other one.
If I could mix that 49/11 with my 35/15 I could get 10.39 ratio, Perfect!
Let me know if you have any 49/11 gears you could part with!

So I've been looking at the gears wrong this whole time LOL thought I had 5.1 and 2.33 gearing, NOPE finally understand the primary and secondary. I've got 3.4 primary and 3.5 secondary. So a gear up kit will work, I'm looking at this: www.ebay.com/itm/202-1332-INGRANAGGIO-ALLUNGATO-POLINI-SUZUKI-MALAGUTI-ITALJET-/261803800798?pt=LH_DefaultDomain_101&hash=item3cf4b8f8de40/14 is 2.85 and its secondary so will give me 2.85 * 3.4 primary = 9.71 final letting me reach about 61 @9000 (peak power) instead of 50-52@9000. Will I get to 61? I don't know, I know it feels like it runs out of gearing and even though power drops off at 9000 it still has enough power at 9200 to get me to 54mph so who knows how much further it can go? Now I just gotta come up with the money  |

Also according to this diagram:  it seems the gearbox can be taken apart on the CVT side rather than the wheel side? Jwhood is this correct? |

Looks like it. Some of the Mina engines are like that too. You can see one having a gear swap done HERE just in case that's of interest. |

I'm assuming I will need to press the one secondary gear onto the driveshaft, and the other secondary gear onto the primary gear.
How hard would this be?

The large gear has splines in the center in that link you posted. Should slide on judging by that. The other will need the old gear pressed off and new one on. Some people have said gears are a real pain to install. So far the folks that have done Malossi primary gears for the Mina here have said it's rough. Normally it shouldn't be a big deal if you have a press. Some use alternative methods. If you wanna do it easy, take the new gear and the old one to a machine shop and get it done.
What I did for when I try gears on the TaoTao was buy another countershaft, the one in the center. Figured then I could press the stock gear off of it and install the new one. Then if I wanna swap later I can do it without any pressing. TGB gears prob cost more and are harder to find than the 139QMB stuff though so it may not be worth it for you.

My machine shop guy took a couple of measurements and shook his head. Went to the press, scratched his head and then went to his big boy press. He got the job done but he wasn't sure he would. I never measured them but apparently they are tight.

Yes that is correct but if your replacing the shaft coming out wheel side you will need too take off wheel!!I would get the pre-pressed gears stage 6 makes some for Tgb scoots,even some Mina gears will work!!! |
