50mm bore, 35mph, please help

[Pierce ramsay]

ok so here is the scoop
50mm bore poli
9:1 gears
8.5 rollers
28mm V8 exhaust
24mm carb (45,130jets)
ct intake
and i still only go 35-40mph and i cant grab full throttle or she will die and bog out, please help.

one more question, i am premixing 40:1, i took the tube that normaly goes to the carb from the oil pump and screwed a screw in it, she leaks only barley, i want to take my oil tank and make it an extra gas tank with a "T" fitting and combine the gas tank and the oil tank as one tank.
so here is the question Can I Run with a Screw in the oil delivery line? and then connect with gas line????? or is running the oil pump dry BAD?
here is a link to the oil tank becoming a gas tank idea

Your main jet is to big. Try a 120. If your carb has the power jet,disconnect it.up that pilot to a 48 or 50.

running the pump dry is bad, get a hold of vtcycles and get a pump plug for you scoot. and if you can modify you oil tank outlet to accept a fuel fitting then by all means go for it. might want to post a how to after you results have been proven to work.

VT cycles is no longer in business

Scooter assasins has one for close to $25 which is pretty steep. You could make your own out of change for about $3 bucks

the power jet carb has a hose that goes from the float bowl to the mouth of the carb.

ok i have a screw on the top of the carb, is that ok, should i remove it, or should i take the hose off?

[Bear45-70]

This is a powerjet carb. The power jet is the hose from the front top of the float bowl to the top of the air inlet.

[bakaracer]

Disconnect the hose from the top nipple and plug the hose with a screw .

You can purchase vacuum line caps at Autoparts stores and just cap the barbs,too.

[Bear45-70]

Or just force a BB or a small ball bearing into the hose and reconnect it to the nipple.

Consider dropping the needle while you wait for the 122-118-115 mains to arrive.
The pipe is a determinant of the optimal Main size, as is engine displacement and even the Air's Density Altitude.
That said, Flash liked the 118-120 @72cc and PG Long.
