Starting point for new fmf jetting!

[gb blaster]

Hey guys I got a real good deal on a fmf gold series. I got it for 30 bucks with a power core 2 silencer because the guy didn't think that he could find a flange. Anyways it's got a little rust but it's good!

My old one had a crack in the expansion chamber so I'm glade I found that out and have a new pipe

Anyways I need to know about where to start on jetting I have a couple ideas but more info wouldn't hurt. I wanna do it with as little plug chops as possible because I get the cops called on me riding in the feild by my house.

Blaster stock with no air box lid. And it has boysen dual stage reeds. I'm at Maryland attitude 21040 is the zip code.



ALSO the silencer isn't packed! Does Brillo pads really work. Just intill I get the packing in its on order. But the flange will be here this week that hasn't even shipped yet!

most start at a 270 fmf recomends a 260 with just the pipe lid on. but a 270 is a solid place to start

FMF = #260
No lid = #280
Foam filter = #290 - #300
32:1 = + one more.

I'm at 300 with the same reeds and pipe with lid off..

We run a 270 with same mods at sea level. Plug is cardboard colr and motor runs at 260 degrees. Every bike is a little different, but you will be between 260-280 depending on elevation and temp.

Alright well that's a lot of difference in option. So of the three jets I have a 280 is the smallest. Would that be a good starting point It seems between 260-280 is the most popular but my blaster is at 240 now with just lid off I guess I'll use the 280 or 300

 

[Wifesblaster]

What is your elevation where you ride?

 

[gb blaster]

Uhm 396 feet above sea level it's in Maryland. It's not that high!

 

[Wifesblaster]

Throw a 280 in there and plug chop. I'd be willing to bet it's dead on on a hair rich. Pm sent fellow Marylander

 

[gb blaster]

Alright well I guess u have some Maryland experience then
