2n1 rejetting

[pitbull2424]

I have banshee with 100 over bore, vforce reeds, a 2n1 carb kit 35mm, 21cc domes, main jet is at 180 and the needle clip in the center spot, pilot size unknown. Bike has just been rebuilt runs strong at the top end but has a very hesitant take off to mid range, I have messed with the jetting up and down and can't figure this one out and I'm blaming this on the 2n1 system. Any suggestions on this one? I am at 5000feet. Also the bike seems to smoke alot more on the left cylinder I'm blaming this on the pilot jet because it's on the left side and I figure the 2n1 just sucks up the left side quicker but I don't know I'm kinda lost with this one. I'm thinking of going back to a two carb set up unless anyone can help me fix this plz. Thanks!

im not a fan of the 2 into 1 and have always been a firm believer in dual carb setups on the banshee. there are people here who use the 2 into 1 though.

 

any idea what size your pilot it?

Sounds like your pilot size is to big. I have this set up on one of my bikes. I'm at sea level with 42 pilot 178 main 4th clip with just a little less then 1/2 turn out.

It works better with low to mid range pipes, like fmf's sst. This is just an idea of jetting at sea level. I don't know about 5000 ft.

looks like i will have to look in to the pilot to see what size it is i now the bike had a 160 main when i got it but seem to me like it was getting hot????

Whats the needle size? Whats the pilot size? Where is the float height set?

Needle size 45 that's all I could see on the slide and needle, pilot size 35, and on the float that is something I have not checked do you think it might be overflowing?

[Snopczynski]

you have to take the needle out to get the size off of it. It should be In Example "EEK"!

Single carb is not your problem. Jetting or settings is the problem. Mess with the air screw and see if that helps
