G14 Engine Swap

procharged93 · 11-04-2019, 06:03 PM

Looking for ideas on what to put in my yamaha G14. Vegas carts doesnt make a kit to put the 625 in there. What have you all done as far as swaps. We use the car to push my racecar at the dragstrip. Looking for a power increase over the stock motor with no governor. Thanks

Vanguard of course.

Vegascarts does do one for their DIY VC 460. I have been racing around in mine since 2014

I havent got any experience assembling a small motor like that.

raydhd · 11-04-2019, 08:08 PM

The other way is buy a honda 390 or some 420 chinese clone and use their install kit. Or can one of your friends involved with your drag car do it ?

How detailed are the directions with the DIY kit.

Save yourself some headaches buy the Vegas install kit and a 440 duromax or a 420 predator or Lifan my 2cents
Or a Vanguard if you don’t mind lifting it 4inchs

The diy instruction in my opinion are very lacking.so much so I called them when I assembled one.i was asking for ring gap specs,rod bolt torque specs,bearing clearances.i got told its just a lawn mower engine specs aren't that important.however that was a couple years ago and maybe they have improved. Also they still are not very hard to assemble.even if you had questions you could ask on here.

The instructions dont look too bad. Ring gap would be ni e to know.

I used the Honda GX 390 ring gap specs which is .20-.40 mm or .01-.02 " s. Also used the honda torque specs for bolts not listed by VC. The honda specs are listed all over the net.
