Freestyle Jetting. FS 48s on 771

[Brian_216]

Can anyone give a starting point for full spec 48s on a 771? It seems everything is for 46s on that motor.

look at that database in the general forum. that database could possibly end questions like this and others.

I got recommended a 130 main, 127.5 pilot on 48 FSs on my 850 SS....

 

[txsuperjetfreak96]

Yeah kinda what i thought

 

[txsuperjetfreak96]

Single carb setup, dnt know if thats to make up the difference or not

 

[Tyrant1919]

Oh , yeah, single carbs go up there. I run a 160m/140p on a single 49FS on my 701 superjet

 

[txsuperjetfreak96]

Ok cool deal

Ok, Ed returned the call and we are on point. safe to start out.

He stated
1.8 Ns
135 main
122.5 pilot
80g spring
23.5 pop off

Going from here and will post in the sticky under carb data base once tuned in and have the final specs

Thanks guys for the input. And thanks ED

Yea checked the database.. Nothing in there for a 771 on dual 48 full specs hence the new thread.

How did this jetting work out? I have a pair of BJ 48's I am thinking about running on my 771.
