PLEASE PLEASE Give Advice on Starting Point

[Infamous039]

I picked up a set of 28mm Carbs for my bike. I need some insight on where I should start and get close with jetting them. I need help starting with the mains, pilots, and needle clip. I currently have 150,152,155,158,160,180 mains 48,50,60 Pilots. The weather is about 70-80 degrees in Somerset, NJ.

 

 

Motor Mods:

 

CT Racing Port Job (See pic in Sig)

Cool Head 21cc domes

+4 timing

Rocket Pipes

KN air filter with box no lid

Vforce 3 reeds

Stock Crank

[SAVAGE420]

160 Mains.

 

50 Pilots.

 

Then go from there.

 

Might end up at 158 or so after you check.....

Would the 48 pilots be good, since I have them installed already ????

exactly, 50/160 is great starting point, by buds bike with rockets like a little leaner needle as well.

what mains were in them when u got them?. i have 28mm pwk's myself and bought a bunch of jets,,,pulled the jets and they were 125's,,,the reason being is they use a rich needle requiring a smaller main jet and run like a 60 pilot. apparantly dirt bikes are set up like this so i spent $25 for jets i couldnt use,,,i ended up at 128's,,,,they were out of 127's is where i want it to be,,,,just a thought man...

i would say yes,,,just start at 160 and work your way down

When I got the carbs they have 180 mains and 60 pilots which has to be extremely rich on my motor setup???
