Changing from race to pump gas??

DASA 865 PV engine currently 220psi.
Can a guy change domes to run pump gas without any carb tuning??

I do it all the time.

I haven't ever done it as I ride mostly stock motors, but here's something to keep in mind. Would you have to make sure to run recreational non ethanol fuel for that to work? In the Midwest most of our gas has 10% ethanol which will lean out the mix if you're switching from race gas. We do have 90 octane recreational fuel available that does not have ethanol in it.

Good point!
I do have access to non ethanol premium fuel though.

I should have said that, I always run non-ethanol 93 as my pump gas.
