There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Tommy, I don't think anyone has done it successfully, with or without a ECM flash.

The Limited comes with 28/79 final drive ratio.
The F3-S and Base model F3 comes with 28/ 89 final drive ratio.
This is true for North American sales models.
I don't know for sure, but it might be possible to install the pulleys and belt from a stock F3-S on the Limited.
It is also possible the different fenders, belt guards, etc would interfere with the larger rear pulley. It might require some modifications to do the swap.
Speedometer would be wrong. Might also run into some other, more serious problems.

The sprockets and belt can be physically installed with out much trouble. The nanny does not approve and the settings in megatech BUDS are as yet unknown. There is a setting for the rear sprocket size but changing this alone does not fix things.
The short answer is that no one, even with an aftermarket tune, as been able to make it work. If you want the large rear sprocket, buy an F3S.

2017 was the last year for the 89 tooth on the F3-T. From 2018 on, the F3-S is the only one with the larger 89 tooth sprocket.
