ever since i port matched my case to fit a polini kit. it doesnt haul ass anymore.
ive gone thru my set up over and over.
it works best with a 15 bing 92 jet. and im probably hittin low 30s ( before i used to be boosting to 55 with a 4p )
my 4 petal dellorto set with a 19 pbhg 105 main with a 6p gets around the same speed area.
i havent changed my gearing yet. i keep thinkin that there should be enough power going to my kit to get me there after riding a flat mile.
i think im getting braindead from petrol huffin.
BTW ive had this polini for 2 years and gone thru 3 pistons and 5 rings.
could it be time for a new kit?
it still has good compression. and it seems like it will pull when its on my kickstand but as soon as i get on it. i get nothing. my ported stock cylinder pulls harder than this thing.
i ported accorinding to specifications. i noticed the loss of intensity in my polini after i ported . is there some guidelines to follow to set up after to tune it? b4 i got out and grab a new polini?
