I've been fooling around with a solution to the problems I've had with a non standard carb. and manifold on a 150cc GY6. None of the after market carbs. or manifolds seem to fit properly. I've always thought that a downdraft carb. might be the solution to my problems, however it has been hard to find a inexpensive downdraft card. Keihins and Mikunis run in the hundreds of dollars. Excellent carbs. no doubt, but way to much to spend on a GY6.
My answer was in a Yamaha 250 V twin clone. Vento calls it a Pony. It's kinda looks like an old Honda Rebel. A 26mm downdraft Carb. that can be had for less than a 150 bucks and it has an excellerator pump.
I had to make a short manifold by hand to fit it on the engine.
Here's where I mocked it up to see how it would run. This is on my daily driver 155cc, 59mm bore commute scooter.
Here's a short video of it running. It did very well with a 35 pilot and a 120 main jet. My cameras speaker really sucks for audio so all you can hear is the intake sucking air.
I wouldn't waste the cash or the labor on a relatively stock 150cc but if you had it bored and stroked in the 180ish range. You might consider it.
