98bansh_ Posted June 13, 2005 Report Posted June 13, 2005 I'm new to jetting I was hoping someone could help get me close on my jetting. I got a stock 98 banshee and putting on FMF Gnarlies and a K&N air filter. My elev. is 1400 above sea level and temp. is about 75. also how much of a change in temp before I should change my jetting again? thanks for any help. Quote
endofitall9 Posted June 14, 2005 Report Posted June 14, 2005 Man alot of guys won't answer this question due to the fact it has been posted thousands of times, there is a jetting article at the top of the page and the only way you'll know it needs to be rejetted is the way it is running and by what color your pluggs are........have a good one Quote
dajogejr Posted June 16, 2005 Report Posted June 16, 2005 True...covered time and time again...but, to help get you in the ball park. If it's a K&N and you're keeping the airbox: 260 to 290 Main 27.5 or 30.0 Pilot (25 is stock) If it's a K&N Pod air filter setup (NO airbox, clamp on to carbs) 270 to 310 Main Same Pilots as above. I read the sticky on this forum about jetting...and it go me very, very close on mine....It looks like a lot of reading, but it is great, great info.... Quote
05bansh Posted June 16, 2005 Report Posted June 16, 2005 (edited) Also if you are still using the stock needles you should lower the clips one notch toward the blunt end. Edited June 16, 2005 by 05bansh Quote
Ducman Posted June 16, 2005 Report Posted June 16, 2005 #30 pilots, air screws 2 turn out, needle middle clip, 300 mains for K&N with lid off, 280 for K&N with lid on (snorkel removed). Add 1 main size if it gets below 55 deg add another if below 30 ect. ect., subtract 1 if over 90. Quote
dajogejr Posted June 16, 2005 Report Posted June 16, 2005 You think he needs that rich of a main at 1400 feet still using an air box? I have none with T5s...and I'm at 330s. You definately have a ballpark figure for your jetting now...it's up to you to fine tune it... Quote
97banshee350 Posted June 16, 2005 Report Posted June 16, 2005 i dont want to take over your post but i have similar mods and sea level, i have mukuni 28mm flat body carbs, could i just go to a dealer and get the jets i need or will they not work with the flat body carbs? Quote
dajogejr Posted June 17, 2005 Report Posted June 17, 2005 You can go to the dealer and get the mains, I'd bet. I'm sure the pilots and needles will be different, though.... Quote
98bansh_ Posted June 25, 2005 Author Report Posted June 25, 2005 I jetted my banshee with 260 mains stock pilots and moved the needle clip. Its got alittle stumble on take off but not really that bad and it seems to pull good but seems like its running hot could it be running lean yet? It also takes a few more kicks to start now. All I put on were my FMF Gnarlies and silencers and removed the snorkel. Quote
dajogejr Posted June 25, 2005 Report Posted June 25, 2005 Check your plug to see if it's running lean. And...yes, if it's lean, it's running hot. What pilot did you put in, and what about the air screws. Put your needle back to stock, middle clip, too... Quote
