blaster 760 jetting

[QuickMick]

If anyone can help me with my jetting I would appreciate it.

I put a 64U 760 in my blaster.
dual 44 stock
FP limited chamber for blaster
ADA head 38 cc domes 180 psi
no porting pretty much stock

Im at a loss where to start my jetting.
does anyone have something close with a baseline
on my jetting so where I can start??

anyone would be appreciated.

you need to lose the stock carbs and intake. i have tryed and tryed to jet the stock carbs with a factory pipe it dont work. get a set of aftermarket 44's and a r@d manifold (with out the crossover) i have the jetting written down in my shop i will post it later.

some good info but i think i only saw one setup with dual a/m 44's on a 760.

im currently running 120high , 120 low, 2.0 n&s with black spring. it runs well but i'd like to try different jettings to see if i can get some better low end.

with the stock 44s you always have a funny spot at the conversion from the low to mid . i could never get it out. my jetting i fixed that issue and can run w.o.t all daty long.(with after market 44')
i will post it

You have a problem with your carbs or your jetting is off.

Remove the bottom allen screw for the bypass holes and the low speed mixture screws, you'll have deposits blocking these ports.
