Default low speed needle question. need some opinions

hey everyone, i recently got a new mgt 8.0. the factory suggested setting for the lsp is 5 1/2 turns but it seems to run best and at good temps at 7 1/2 turns out. It pulls great wheelies and shoots out from a stop like a bat out of hell so it can't be to rich. It just seems like 2 full turns seems like a lot past the factory settings. Can this be ok? I read the tuning bible and it does not seem like the lsp is keeping the rpms down from having the carb to open.
thanks
ben

thanks for the input. it just seemed like 2 full turns past factory seemed like a lot when i thought you were supposed to lean both needles after break in.

normally you would. Is your idle gap pretty far open?

Maybe its not broke in yet? Air temp plays a factor in your settings to. If its cold out, you'll have to richen needles.

as far as the idle setting the opening is very small. and it has been pretty cold. yesterday it was mid 40's. i guess i'm not sure if it fully broken in yet either. i am still fairly new at this stuff. the engine has "cleaned out" a couple times. in the instruction book it says that cleaning out is a good characteristic of broken in engine.

If its running good with good smoke, your golden! Mid 40's would explain the richer settings along with being a newer engine.
