04 major missfire

[2004limited]

i got a 2004 banshee this is the third time i have had this problem. when i bought the bike it would wun good intermititantly but bad most of the time and was spitting gas out of the right pipe cost 270 to have the carbs rebuilt. ran great for a month. put fmf fatty and power core pro flow kit and k&n jetted myself ran great for about 2 months went on vaccation and had to rejet the bike for elevation and temp diff ran good 2 days then just quit. no acceleration or power. revs good. tore everthing from the heads back off cleaned nothing wrong disconected the tors. finaly took out the choke and tube cleaned then ran great.

 

this time rode for about an hour then started to loose top end checked plugs good. pulled choke and cleaned ran good put gas for another ride and no power at all . pulled both carbs and cleaned everything put together and no power. loaded up and brought it home. took off the trailer and cracked on it first gear ripped good, then second gear on all bog

 

just wondering what the problem could be the carb has been rebuilt every year since new its starting to get expensive

well, did you account for the fuel at the new elevation? if it's a big jump, like 2000' or more, the fuel will change, and you will need to go the other way a few sizes on the jetting, once you put that new fuel in....

Sounds like electrical problem,plug caps, coil,something frayed in harness with bad connection,I cant imagine stock carbs giving you that much trouble,too me there set it and forget it,is there shit in the gas tank

when you pulled the carbs appart did you put the float bowls back on the right carbs? the float bowl with the long brass tube inside it goes on carb with the choke plunger.(left carb)

k this weekend i pulled the reeds left reed stuck open replaced with boysen power reeds same problem

pulled the carbs apart again found that the needle jet was bent brought it back to the people that rebiult it and they said the only way that could happen was during reassymbly and they were the last ones to pull the tops off rebuilt the carbs again and same problem

 

 

it jsut feels like it is loding up real bad and if i feather the throttle i can get the rpms up but if i hammer it runs like crap

 

i got stock tors, fmf gold series fatty with power core, pro flo kit with k&n,

main jet, 280, pilot 25 air screw 2 turns out
