first time jetting

Recommended Posts

Hello everyone, I'll try to make this as short and sweet as possible. I recently bought a banshee a few months ago, It seemed to be running good but after my first long ride my top end went boom, my guess is that it was always running lean. Now I am waiting on my cylinders to get back to me

but I want to make sure my jets will be on the safe side before I even go to break the engine in. So here are all my specs+ mods, I did already rejet so I just want to make sure I should be in the ballpark and safe to fire/ run the new top end.

 

Exhaust: fmf gold series, powercore2 scilencers.

 

Intake: stock airbox, no lid, prodesign k&n pro flow kit with outerwears pre filter.

 

reeds: boysen carbon fibers with stupid boost

bottle.

 

Elavation: 700 to 800ft

 

riding temps: 70- 85F

 

oil/mix: 93 pump with amsoil interceptor 40/1

 

porting: no

 

Stock carbs w tors delete.

 

Pilot: 30

 

needle: middle clip

 

mains: 280

 

air screw: 1.5 turns out

 

this all sound about right? thanks a lot for your time everyone! I hope to get this damn thing back together and ride it before summer is gone.

Well based on his mods and based on if jets were at stock this was the calculation I got but he did blow it because he was lean, better safe than sorry by going rich but only a plug chock will tell
