If everything is modified right & the tune-up is sound. You don't need the pump.

 

We started with a pump on our 1/4 mile 443cc quad & weaned our self off the pump when we had the experience. 1/4 mile & the hillshooting put the greatest demands for fuel delivery.

Are there any needles you recomend

[nito.hernandez1]

Im only gonna be running the 1/8

[nito.hernandez1]

And im on asphalt

[SlowerThanYou]

When we 1st started running asphalt we ran 35 PWKs & they had custom needles. We switched to race gas & to 39/41 PWKs with a DGH needle.

 

When we built the 643cc DMX we converted our 41s to Alky we use the DGH needle, dumps drilled .120, 55 pilots & power jet discharge tubes drilled. Cant's remember the size somewhere around .100. This set-up was only tested on asphalt at the airport for around 400', but has been tested at 300' sand.

 

The bowls are the Boss ones & are the largest I know of.

 

What size PWKs?

[nito.hernandez1]

39 mm

[nito.hernandez1]

[sleeper06]

I run alky pwks gravity fed in the 1/4 with no issue , oversized bowls , one float cut off, .1225 dumps and mains ,4 mil small motor, a few little other mods to the pilot circuit and power jet dump is also drilled but can't remember size

[nito.hernandez1]

K thanks

[nito.hernandez1]

Im gonna measure the dumps main an im also gonna cut off one side of the float for more fuel space to be on safe side also look into the needls situation

[nito.hernandez1]

Mind me this is my first alky bike of my own that im building i bought the carbs already drilled out an was told that they where set up for a basic motor set up meaning not a big boy

[sleeper06]

Well usually u drill carbs to a particular set up not motor to carb so hopefully u don't get screwed by carbs too big for your engine, porting , domes, timing, pipes all come into play , I would send them to fast racing and have them inspected and measured
