I'm about to try a modification on my pair of Keihin FCR 35s and am wondering if anyone else has done this before - and is willing to offer advice.
The slow fuel mixture screw on these is hidden up a vertical hole toward the front of the bowls.
Given that adjustments should be made with engine at operating temp (hot!), fiddling with a screwdriver up these ports is uncomfortable to say the least.
I have bought a couple of "extended" mixture screws from the Australian Keihin agent with the hope that the adjustment can be made as easily as changing the idle speed.
They advised me, however, that they were made for the MX versions of FCRs and that "slight" drilling will be required on my bowls to allow them to fit - it appears that the vertical ports need to be opened by about 0.5mm.
Anyone done this before and have any sage advice?
Cheers
