yea, i posted in the truggy thread in the mt forum, they know their stuff, dunno if they care about a cen mt enough to reply tho.

that 11t really does make it fly tho! instant flippability! i did rescuff both the shoes and the bell tho, it is freaking the diffs out a bit as it squirms around looking for traction .

rounded the head of the 2 speed adjustment grub screw.... gotta get another 2 speed clutch - £10 is the best i have found on ebay so far, from an mt, so the spring might work ok. 2nd is gonna be very frightening i think... will have to wait for the 11/15 ofna/ho bao bell tho. maybe get a 12/16 too, see if it hooks up without flipping so easily. thats if the ofna pinions line up ok, or will they screw onto the cen bell with some mods...? we will see.
