tried fitting 34mm mikuni flat slides to my power valve motor before i stripped it to send the thing for a race tune . the inlet rubbers are obviously to small but the bowl of the left hand carb fouls the clutch actuator that comes out on top of the gear box . i found a web site who make special inlet rubbers for this job , but i didn't save it and now cannot find it . anybody seen it or know another vendor for such things

I dont know how it would run,but i have seen a bike with the inlets turned upside down with the balance tube at the bottom . I know is sounds odd and it does look od but i did see it on a bike and it was running well.

well spotted , me and my buddy tried turning the carb rubbers as well to see if it fitted , but same as you not sure how it would run . one of my mates who used to race rs 250s said the problem wouldn't be with the carbs as they sit at strange angles on aprillas anyhow . wouldn't fuel slowly build up in the balance pipe over a long time , not sure on this one wish i'd tried it before i stripped the bike

Not sure . Just know i have seen it on a bike thats all , Sounds a bit funny to me . I have a set of 34mm carbs on one of my ypvs 's and they fit. I had to bend the clutch bit down a bit and shave a little of the bottonm of the carb but they fit and run fine .

Yeah.. it's a bit large/ugly. IMO these things are of little real world value..
But Yamas' R&D work claimed 175cc Per Cylinder .. not cross connected!. was the size boost bottle that showed (slight) documentable gains,, so the size is actually closer than the tiny shiny ones
However the PoyU carb boots are 'Just fine' by anyones yardstick.. bit pricey though.
