270 main to small for this setup

[bbruischart]

I bought a banshee with fattys and turbine cores, with boysen reeds, no airbox, dual k and n. This guy had 270 mains and 11.6 pilots. Are these pilots even for the quad. I bought it right after he installed the new filters but no bigger jets. It popped the next day definite signs of a hot motor.thanks guys. I read the article on jetting already. It sounds like i need 340 and 30s with the needle dropped one for reeds. I live in michigan. 800 feet above sea level. does this sound right.

Don't know what a 11.6 pilot is, stock is 25 and go up from there. Id try 27.5's before jumping right into 30s. Mains could be lean, Im at 800' as well and with pipes and single k&n mine took 340s. That seemed big compared to most but i'd try 300s and do a proper plug chop!

 

Those filters will definately lean the bike out!

Thanks man. the jet seriously says 11.6 on it. I dont know probably why she went.

my mods are in my sig and im running a 260 main right now and mine is perfect. weird because everyone is runng 290 and up, mine just may be weird. just had to comment.

That is wild man this thing went from right to hot and burned up with a change in filters and a 270 jet. Thanks for the input though, Its nice to know that jetting is a science and every quad is different.

[peak-j]

Yeah, I have always wondered why there is that much difference in jetting. I have 280 mains, 25 pilots, and I am at 1000ft. Been running good for about four months now. Never heard of the 11.6 pilots either.

I just put my t-5's on... i put 280 mains, needle on middle clip and 25 pilots (thanks socalinit :thumbsup:) . I also bought 27.5 pilots but it seems to run fine. I have not done a plug chop yet, but it isnt lacking in any power. I also have a k&n air filter with the lid on. I ran it with the lid on because i wasnt going to do a plug chop and i wanted to be safe from running lean. Every bike will most likely have a different need as far as jetting goes... you can only ask other people with the same set up to get a start... and then the tinkering begins

 

edit: im pretty much at sea level... like 30 something feet above

With the pod filters and fattys I'd go with a 27.5 or 30 pilot, and 320 mains

270 may be a bit lean but it shouldnt of popped that quick from the mains. i dont know whats up with youre pilots but i would look there first. maybe thro in a set of 320 mains and 25 pilots. do a plug chop and i bet it will be close.

if its not close, check for air leaks.

Thank you for the input. I bought 330 mains and and i am going to try them. My engine builder is out of town, and im still waiting on my head, I had to have it milled. Hopefully he gets home soon, cause im going wild. Like I said Thanks,

 

Thanks everyone, you have helped me more in 1 week than my local shops could have ever imagined.

With pod filters and T5 pipes, being from Michigan also...I would love to see your plugs after a proper plug chop...

Something is not right with 260 mains, pipes and no air box. I can see a 300 or 310...but 260?

That's what jetting I start out with a stock air filter, with lid and pipes....

 

Either that...or those filters just restrict that much air, and I can't see that being it.

 

27.5 pilot, 330 main to start.....you can fine tune it from there.

The did you actually pull those pilots out of the bottom of the carb...or are those the air jets that are in the carb bell?

[tyguy]

im trying some 290s bc thats as high as i have and ill let you know on how it compares, its deff not lacking in power, i thought it was really low to but thanks dajogejr,youve always got me thinking,

 

not trying to steal the thread, sorry man.

Yeah. turned out im an idiot. I did pull the jet out of the bell. I am used to working on drag cars and the quad tuning is relatively new to me in the last 3 years. I thought that after all i have read the 330 and the 27.5 or 30 would be about right to start. I am going to put in the 27.5 pilots today. Still waiting on my engine guy for the final fire up. Thank you I really needed everyones input.
