wesw Posted December 4, 2003 Report Posted December 4, 2003 need some help i am going to buy my sister a pro design filter for her z 400 for x mas. i was wondering what main jet i should run. i was guessing 2 sizes bigger than stock but hell idont know what stock is any advice Quote
JKJK Posted December 4, 2003 Report Posted December 4, 2003 it all depends on how it was set up at the dealers.if the jetting is correct now ,then 2 sizes up sounds good+adjust the fuel mixture screw.assuming no other mods or changes.i'm from the northeast at see level+my z came stock with a 130 main jet.to optimise her gift i would also get a dyno-jet kit .part #o312 comes with needles,a good assortment of jets,+good instructions so you can really dial it in.

wesw Posted December 4, 2003 Author Report Posted December 4, 2003 whats that kit cost roughly. my bitch is i just cant go ripping bowl off and look athe jet with out her know what is up. well guess we will figure this out on x mas day Quote
bignasty1 Posted December 4, 2003 Report Posted December 4, 2003 my bike had a 130 in it and i'm at about 850 ft above sea level and i yanked the lid and added a 155 along with my k&n i also have a yosh slip on as well tho so you may need another size but go ahead a ditch the lid while you at it nice lil increase in power. jmo.

JKJK Posted December 5, 2003 Report Posted December 5, 2003 the kit i recieved came in a package deal,so i'm guessing around 75.00 money well spent. Quote
wesw Posted December 6, 2003 Author Report Posted December 6, 2003 did you notice more power from the filter or the exhaust. probably put them on together i was wondering. Quote
JKJK Posted December 7, 2003 Report Posted December 7, 2003 first mods to virgin z went like this.pro design billet adpt.k+n with outer ware,pro-c t4 slip on,dyno-jet needles+main 146,3 clip from the blunt end,mixture 3 1/2 turns out.removed snorkel, lid on.gains were obvious,crisper throtel responce+broader power!remove the snorkel get the filter kit,up the jet,+you should notice a slight increase in power,it can only help.
