TQ options for 25hp

[Holmeswilliam86]

Getting done with the gx390 build, mild cam, crank, heavier valve springs, longer rod, slightly shorter piston (sits .05 below) , thin head gasket, ported intake and exhaust. Still waiting to buy a 34mm carb but with no Dino I’m still assuming this will make more than 22hp and looking for options with drive trains.

Thinking a 40 series

But still wondering if there are better options other than a $500 500 series. What are your thoughts?

94c Duster comes to mind that's rated up to 40hp 4 stroke. Itll be close to $400 for the driver and driven.

The 780 would also be one to consider. Perhaps slightly undersized (20hp 4 stroke), but definitely beefier than a 40 series.

Any recommendations on where to buy either one ? Somewhere not over priced

Pricing will be pretty level across the board. GPS or BMI probably the easiest. "Overpriced" is relative. If you're comparing against a Chinese 40 series, they're all going to be "overpriced".

Plan on spending $500+
