Thanks for the info, everyone!
I have set fuel records on both of my race bikes in the past but just running gas. This year I aim to play and learn with methanol.
If you are having fuel supply problems with gas, you have a LOT of headaches ahead with methanol, although, once set up correctly.
I use a single TM-32 Mikuni on a 250 blown Honda & also had problems with adequate fuel flow, the Mikuni needle & seat cant handle much over 1.5 psi.
The facet type "rattle" pumps bounce the needle off the seat, so I went with a low pressure (5 psi) high flow Mallory electric pump (5 amp draw) & to get around the pressure problem with the Mikuni, adapted a Holley float bowl that feeds into the empty Mikuni bowl
Mikuni float bowls are, in my opinion, too small for methanol use.
You will need to increase your jetting to flow 250% more than gas when using methanol (All flow, not just mains)
