Drturbodiesel Posted March 24, 2013 Report Share Posted March 24, 2013 Finally tore down banshee for top end rebuild. Was bone stock and still ran well was just getting weak on one side 120 and 80 psi comp was reason for tear down. Anyway will be runnin pro lite pistons. Stock porting but will also be addin fmf fattys k&n with pro flow. I'm at 164 feet elevation. I got some 280 mains to start with. But I noticed one reed was not closing by itself like others. So was going to order v force 4 reeds. Is it also a good idea to bump pilot up to 27.5 before I even start it ? Thanks just tryin to get most parts ordered before cylinders come back from maching Quote Link to comment Share on other sites More sharing options...
oldskool Posted March 25, 2013 Report Share Posted March 25, 2013 I would prolly go with the 27.5, but the stock pilot will be fine with your set-up Quote Link to comment Share on other sites More sharing options...
Drturbodiesel Posted March 25, 2013 Author Report Share Posted March 25, 2013 Thanks. I know there is no way to know what's going to be perfect besides trial and error. I just noticed that most of you say to bump up when going to v force reeds. By the way is there any opinions on the v4s yet? I would be fine with stock reeds if I dident have a weak one but the fact that there's no screws in the v force kinda sold me on them.

No a stock pilot won't work. If you are doing a top end and don't have porting....try the Vito's super stock pistons. They add about 7 HP for your combo and act like mild porting.

Drturbodiesel Posted March 25, 2013 Author Report Share Posted March 25, 2013 Ok then. 1says it will 1says it won't. Lol and your rite there's prolly plenty of v force info on here just decided to ask since that the direct reason I asked the pilot jet question. ( and I'm lazy) but anyway I think 27.5 it is. And thanks for recommendations Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 25, 2013 Report Share Posted March 25, 2013 I would definitely start out with the 27.5 maybe, just maybe a set of 30's. With the results I've been seeing on them you will probably be ok on the 27.5 since you're not ported. However you will more then likely have the airscrew almost all the way in.

Drturbodiesel Posted March 25, 2013 Author Report Share Posted March 25, 2013 Thanks. I'm definenently wanna start with 27.5 for baseline Quote Link to comment Share on other sites More sharing options...
oldskool Posted March 25, 2013 Report Share Posted March 25, 2013 Go with what the other two guys are telling you. I'm positive they have way more experience than myself when it comes to jetting a banshee. Quote Link to comment Share on other sites More sharing options...
SpecialEd 05 Posted March 28, 2013 Report Share Posted March 28, 2013 I ran mine for 5 years no problems with stock pilots & 280 mains with Toomey T6's, VF3's and Uni Filter. I had to run with the lid on and snap in vents as it lost a lot of power with the lid off. I decided to do a top end rebuild for the heck of it, still had good compression of 125/125. But now I've jetted to 320 and 27.5 for lid off. Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted March 28, 2013 Report Share Posted March 28, 2013 Go with what the other two guys are telling you. I'm positive they have way more experience than myself when it comes to jetting a banshee. And yet you offer advise that could potentially burn down an engine....WIN!!!

oldskool Posted April 7, 2013 Report Share Posted April 7, 2013 And yet you offer advise that could potentially burn down an engine....WIN!!! Never had any issues with 25 pilots on stock cylinders with T6 pipes and pods, BUT my carbs had air/fuel mixture screws for small adjustments. Put that in your pipe and smoke it!

Drturbodiesel Posted April 8, 2013 Author Report Share Posted April 8, 2013 After gettin mixed replies I think I'm just going to put all stock everything back on it to break in engine and worry about changing everything else at a later date. And that way I know it won't be too lean during break in and ill know how much power just a fresh engine has before I start adding other stuff.then I can see how much pipes jets reeds and filter actually help.

J-Madd Posted April 12, 2013 Report Share Posted April 12, 2013 The Fattys like the 27.5 pilot. If your not running a lid, At least 340s with no lid if your gonna be running WOT in 6th any. Stock pilot is ok with Toomeys. If you can start it with no choke the pilots are at least big enough, if not too big. It may be lean on break in with stock pilots. And for damn sure with stock mains, if that's what you meant. Quote Link to comment Share on other sites More sharing options...
06BCBANSHEE Posted April 12, 2013 Report Share Posted April 12, 2013 same setup as you...def do the 27.5...if u get reeds go up to a 30. im running pretty much the same mods as you at the same elevation. im using 290 mains and a 30 pilot with the vforce 4. if you are gonna use the stock reeds use the 27.5 Quote Link to comment Share on other sites More sharing options...
noonansar Posted April 12, 2013 Report Share Posted April 12, 2013 Im at the same elevation and I run DMC916, open airbox, vf3 reeds, +4 timing. I run 30 pilots and 330 mains in the winter and 27.5 pilots 310 main in the summer. I would definately start with 27.5 pilots and probly around 300 mains. I always try to start rich and work back, much safer that way. Main jets are cheap, buy a bunch of different sizes so you can fine tune.
