jetting mid range phbh, still lean
Posted: Mon Jul 06, 2015 8:42 pm
hi all,
running home tuned suzuki 195, 60mm crank, jl3, 28mm phbh reedspeed cdi. timing advanced knocking back to 17 degrees at 4k rpm. i believe when advanced its at about 23 degrees, will have to recheck which setting im on.
either way, its a bit of a peaky set up which is proving hard to jet in.
currently running 50 pilot,40 slide, av266 with x13 1st clip, 128 mj.
im still running lean in mid range once in the powerband.
i was running x7 needle, couldnt get it past the 2nd clip without it being a pain to ride, and with x13 on 2nd clip its the same, you have to really roll on the throttle as out of the power its boggy.
Im gonna try 2nd clip again tomorrow and drop the main jet, just to see if main is too rich and messing up my mid range.
whats the best way to get the clip position right? i know you can remove main jet, but surely that makes it really rich? or is this wrong due to the jet itself creating greater velocity during venturi?
or is the answer really that this is something i may just have to put up with?
cheers all!
