Thank you for pointing that out! I see now that the geometry is indeed completely different. in fact it seems not only the brake assembly but that whole chassis part has been modified ( see the tubing angles, your middle tube goes perpendicular against the rest of the frame, while mine and others go at a slight 30-35º upwards angle. As you say, it is a good thing skyteam keeps developing this bike! For now, I've found the rear brake sufficient, If you manage your expectations around a rear drum design from half a century ago. ;D Also, If you really need to brake hard (I think the name of the game with the Ace is ''anticipation'' ), I've found that engine braking is really a factor with these bikes; go down a couple gears, while aplying front and rear brake, and it bleeds speed surprisingly well for its specs. It certainly would be interesting to try your rear brake configuration and compare!
On an unrelated note, my K&N filter is about to arrive. Along with it im planning on upping the main jet (currently set for the air box; I'm guessing around high 80's value) on to a 95 main. To fully profit from this, I will try to remove the butterfly choke: not only is it a major disruption to airflow, as stroker crazy put it, but I've found out that the whole choker lever assembly is slightly flawed, and the lever that is at the carb doesn't rotate far enough to fully set the choke to the full open position, leaving about 1-1.5mm play, and the choke slightly canted downards.
Crazy, (and anyone else that has removed the choke) is it easy to remove the choke? I see that the choke itself has 2 screws on the inside of the carb to remove the flat bit, but how do you remove the metal bar that rotates the whole thing? On one side of the carb is the choke lever itself, that doesn't have any screws, and on the other side there's just a flat bit of metal, also without screw. I'm thinking of having to push the bar from the flat side with a cylinder and a hammer, but again, I'm not the most mechanically sound person of the bunch. Anyone with more experience know a better way to do it?
PS: photos as soon as i get home from work. It's being a sloooow day here at the legal department. ;D ;D
