Jeting

[edcadfab]

Hi, i am a new member here, thanks for leting me join. finaly i got my jugs out of th machine shop. My question is were am i as far as jetting. i have a 99' banshee. The bike has 66 mm wiseco pistons, Hot rod crank, cool head with 20 domes, K&N air filters(Box removed) , V-force reeds/spacer, pipes and silencers( unsure of what kind), Curently 400 main jets and 2.8 pilots. I am the 2nd owner so there are somethings about the bike i am unsure of. I am aprox +900 ELV. Will i be able to use the jets that i got now? Do i need to use different ones??

 

 

Thanks

Welcome to the site. I don't know all of too much about the elevation and all that but a 400 main seems way too high. Your pilot should be good as long as you ment a 28 and not 2.8. I sure someone on hear will give you a better idea of what to run. If it helps at all.... I'm running a 96 banshee bored 40 over with a cool headand 19cc domes fmf fattys with turbine core silencers vforce reeds on stock carbs with the air box removed and I'm running a 320 main and 27.5 pilot. Like I said not sure about elevation but I live in Michigan so I'm pretty close to sea level.

Thanks, The previous owner must of put them in. Im sure they are not stock. I never did get to far in jeting. 320 sounds good i guess, im not sure why the other owner put in 400. i did recheck the pilot and it was 28 as there was a nic or somthing on it. would the maker of the pipes and silencers make any difference? I know the pipes are not stock but thats it and the guy i got the bike from is gone far away.lol. I live in michigan to close to manton /lake city .

320 mains sound about right. Try those and do a plug chop and go from there. I have never heard of a 28 pilot though.Then again, I don't know everything.

im not sure why the other owner put in 400.

Maybe because there's an air leak.... Check your manifold and your ummm, boost bottle connects, if you have one.

400 is way to high. In my opinion you should start at like 340 and do a proper plug chop. When jetting you always should start out rich and lean it down. Dont just go by how good it runs because a banshee with a lean condition will run its balls off until it melts down.

Ok so about 320 is the more common answer. so i will start there. as far as the pilot its eaither 2.8 or 28. theres a . or nic, and hard to tell, i tried to take a pic but its way small. im gona open the the other side (carb) and see what i can figure out. I dont have the boost bottle just stock aluminum tubeing. I will go over everything to ensure theres no air leaks. Thank you all for your help

Ok, i got 320 's now. So what about the pilots? i checked the other carb and both pilot jets 2.8 . This could of been why i had so much trouble runing the bike when i first got it till finaly "That Day" when she died. i am not sure my freind works at napa and is into this stuff and said its really weried pilot and most lickly incorect. he said i should start back at stock pilot and go from there. I have been told 27.5 pilot. Is that a good idea?
