Gear ratio help

A fuel pump makes sense, yes;
a small pulse pump will do nicely;
like a mikuni for example.

but since your engine has an alternator, maybe an electric pump is the easier thing for you,
since you don't need to worry about picking up the vacuum signal from the crank case (which can involve drilling into said crankcase),
instead all you need is some 12V signal from the alternator and a return line to not flood the carb

You can get inline electric pumps that only deliver 2 psi for applications like this, so the pressure isn't high enough to overcome the float.

That sound good I'm going look into that

Yet to test it out, but I have a Kawasaki Mule Fuel Pump.

12V
1 AMP
1-2 PSI
15+ Gallon / Hour

I still plan on using a return line with 1/4 turn valve in the return line.
Not sure it will be needed. Testing will determine I suppose. But it will be easy to close the valve if I need more pressure at the carb. Gravity only provides a few tenths of a psi I think, maybe 0.5 psi? I don't want to hit a bump, and then the float needle not seal shut.

that's true... personally I like flowback lines however,
a popped float, a dull needle or a worn seat and 2psi is enough to make a much bigger mess than necessary
But that might just be me

What is your thought on #35 chains/sprockets vs 428
Was just going to call around Monday to see on custom sprocket prices. A bunch of people seem to use it and it is the size chain and sprocket that came with my axle. The chain is a smaller so my case clearance would be better ?

I use #35 cause its about the best allarounder I could get that was afordable.... its also common... A good ratio has also good clearance with the larger sized (eg. 72t) sprockets...
