hey guys, need some help. just installed my esr 409cc cylinder. with the 4mm crank. it came with mikuni tmx 36mm carbs and his pipes , which look like shearer copies. a timing advance plate and 2 k & n filters. with 2 velocity tubes to mount the filters to the carbs. take into consideration that this is a pro x cylinder and the reed intakes are of the cr 250 design. a six bolt pattern. everything bolted on perfect. the problem beingis i cant mount the filters onto the carbs because the pipes are in the way. i have to apply pressue to the carbs and force them inward to put the filters on. if i had out of frame pipes it would be perfect. went from a trinity 2 into 1 setup and this is frustrating. any HELP different carbs etc.. thanks
