Last run of the year today and the bike was running like a bag of s*@t :smt013
Biggest flat spot imaginable between 3 and 4 thou then like a pulsing effect higher up the range
Thing is , the bikes got a dynojet kit and I just can't get it set up right, at the mo its got the circlip set on the second top notch of the needles and its got 92 main jets.
Does anyone on here have a dynojet kit , and if so , what set-up do you run on.
Also, would old spark plugs have any bearing on this ?
Truth is it just hasn't ever been that happy running with the kit at all......
Done some more adjustments with the pilot air screw and balanced the carbs but it still runs too lean at the top of the rev range, problem is if I drop the needle down a notch it becomes too rich throughout the full range almost unrideable down low..... don't know if the pilot air screw would sort that or not
I feel like I'm almost there, just needs more fettling....
if its too lean at the top, (and rich everywhere else if you raise the needles) id say you need bigger mains, the pilots dont affect anything over about 3k rpm and 1/8th throttle, likewise balancing will only cause/remove secondary vibes in the midrange,
do you have any bigger jets kicking about ?
mine had dynojet #90 mains and was WAY lean even with a clogged stock airfilter, chucked some keihin #105s (stock type, for a given number DJ jets flow more fuel than keihin/stock) in, KnN and took the snorkel out (it obstructs airflow to the KnN which only breathes through its sides unlike the stock filter) and its now "maybe" a tad rich, but not by much, #102/103 probably perfect..
get your mains sorted first, then needles, then concentrate on balancing, and idle mix last.
are you running a stock air filter/airbox ?
you say that if you drop the needle down a notch, it goes rich.. dropping the needles weakens the mixture, assume you mean raising the needle/dropping the clip to third from top ??
